BSD.PORT.MK(5)

NAME
bsd.port.mk - ports tree master Makefile fragment

SYNOPSIS
.include <bsd.port.mk>

DESCRIPTION
bsd.port.mk contains the ports(7) tree make(1) framework, in the form of documented public targets, variables and paths.

Identifiers beginning with an underscore are internal-use only and likely to change without notice.

This documentation contains sections covering targets, variables, diagnostics, and filenames, ordered in alphabetic order, followed by a section covering the fake framework, a section explaining flavors and multi-packages, and a section covering the generation of package information.

It ends with sections covering obsolete targets, variables and files, outlining conversion methods from older incarnations of the ports tree or from other BSD variants.

bsd.port.mk also uses quite a few helper scripts which live under ${PORTSDIR}/infrastructure/bin.

Binary package details are mostly covered in pkg_create(1) for the packing-list details, and in pkg_add(1) for the installation semantics.

Common usage such as building every package in the system is covered by ports(7) and bulk(8) instead, with packages(7) providing an overview of the result.

TARGETS

{build,run,all,test}-dir-depends
    Print all dependencies for a port in order to build it, run it, build and run it, or to run regression tests. The output is formatted as package specification pairs, in a form suitable for tsort(1).

full-{build,run,all,test}-depends
    Print all dependencies a package depends upon for building, running, or both, as a list of package names, sorted by dependency order with tsort(1), most dependent port first.

{build,lib,test,run}-depends-list
    Print a list of first level package specifications a port depends as build dependencies, library dependencies, test dependencies or run dependencies.

print-{build,run}-depends
    User convenience target that displays the result of full-{build,run}-depends in a more readable way.

{pre,do,post}-*
    Most standard targets can be specialized according to a given port's needs. If defined, the pre-* hook will be invoked before running the normal action; the do-* hook will be invoked instead of the normal action; the post-* hook will be invoked after the normal action. Specialization hooks exist for build, configure, distpatch, extract, fake, gen, install, patch, test. See individual targets for exceptions.

all-lib-depends-args
    Process the full LIB_DEPENDS list into a form suitable for pkg_create(1), see print-package-args.

build, all
    Default target. Build the port. Essentially invoke

        env -i ${MAKE_ENV} ${MAKE_PROGRAM} ${MAKE_FLAGS} \
        	-f ${MAKE_FILE} ${ALL_TARGET}

check-register
    Introspection target. Verify from the ports tree, without building anything, that the current subpackage will register okay ( see PLIST_REPOSITORY).

check-register-all
    Apply check-register to all subpackages of the current port.

checkpatch
    Check that patches would apply cleanly, but do not modify anything.

checksum
    Compute a sha256(1) digest of ${CHECKSUM_FILES} (files listed in DISTFILES and PATCHFILES) and check it against ${CHECKSUM_FILE}, normally distinfo. In case of a mismatch, running checksum with REFETCH=true will fetch alternative versions of files keyed on their checksum from the OpenBSD main archive site.

clean
    Clean ports contents. By default, it will clean the work directory. It can be invoked as make clean='[depends build bulk work fake flavors dist install sub package packages plist test]'.

    work
        Clean work directory.

    bulk
        Clean bulk cookie.

    build
        Clean the WRKBUILD directory (only useful if SEPARATE_BUILD is set).

    depends
        Recurse into dependencies.

    dist
        Clean distribution files.

    fake
        Clean fake installation directory.

    flavors
        Clean all work directories.

    install
        Uninstall package.

    package
        Remove all copies of package file.

    plist
        Remove registered packing-lists of all subpackages.

    test
        Clean test cookie.

    sub With install or package, clean subpackages as well.

    packages
        Shorthand for ‘sub package’.

    all Shorthand for ‘work flavors packages plist’.

clean-depends
    Shorthand for ‘make clean=depends’.

configure
    Configure the port. By default, configure creates the ${WRKBUILD} directory (see SEPARATE_BUILD), and runs whatever configuration methods are recorded in CONFIGURE_STYLE.

distclean
    Shorthand for ‘make clean=dist’.

distpatch
    Apply distribution patches only. See patch, PATCH_CASES and FIX_CRLF_FILES for details.

dump-vars
    Dump the values of all relevant variables in a port, prepended with the port's FULLPKGPATH.

extract
    Extract the distribution files under ${WRKDIR} (but see EXTRACT_ONLY, FIX_EXTRACT_PERMISSIONS and NO_DEPENDS). Refer to EXTRACT_CASES for a complete description. Do not use pre-extract and do-extract hooks.

fake
    Do a fake port installation, that is, simulate the port installation under ${WRKINST}. There is no do-fake and post-fake hooks. fake actually uses pre-fake, pre-install, do-install and post-install. Override pre-install, do-install, or post-install to change behavior. Do not touch pre-fake unless you really know what you are doing. See THE FAKE FRAMEWORK section below.

fake-wantlib-args
    Check WANTLIB against the list of installed packages and libraries in the ports tree. See print-package-args.

fetch
    Fetch the list of files in DISTFILES and PATCHFILES using ${FETCH_CMD}. Files are normally retrieved from the list of sites in MASTER_SITES.

    Appending ‘:0’ to ‘:9’ to an entry will let ${FETCH_CMD} retrieve from MASTER_SITES0 to MASTER_SITES9 instead. If the rest of the entry parses as ‘filename{url}sufx’ ${FETCH_CMD} will fetch urlsufx instead, but store the result as filenamesufx.

    Transfers in progress are stored as filenamesufx.part and moved after completion.

    The ports framework uses ${DISTDIR}/${DIST_SUBDIR} (aliased to ${FULLDISTDIR}) to save the ports distribution files and patch files.

    If you want to fetch a significant number of distfiles quickly, say all files relevant to a port, dpb -F is more efficient.

    Use of {pre,do,post}-fetch hooks is forbidden, as this would make mirroring of distfiles very complicated.

    See CHECKSUMFILES, DISTDIR, DISTFILES, DIST_SUBDIR, FETCH_CMD, FETCH_MANUALLY, FETCH_SYMLINK_DISTFILES, FULLDISTDIR, MAKESUMFILES, MASTER_SITES, MASTER_SITES0, ..., MASTER_SITES9, PATCHFILES, SUPDISTFILES, REFETCH.

fetch-all
    Like fetch, but also fetches SUPDISTFILES, for use with e.g., makesum.

fix-permissions
    Ensure permissions are correct when using PORTS_PRIVSEP and/or dpb(1).

    If necessary, creates directory DISTDIR owned by FETCH_USER, and creates directories LOCKDIR, PACKAGES_REPOSITORY, PLIST_REPOSITORY and WRKOBJDIR owned by BUILD_USER.

    If these directories already exist, ownership of their contents is modified to conform to PORTS_PRIVSEP and dpb(1) requirements.

gen Generate configure script when needed, either after patching input files, or from scratch for some ports, generally using automake, autoconf, autoreconf and similar GNU tools. This target only has modules (MODxxx_gen) and a do-gen hooks. Then adjust timestamps to avoid regeneration during build ( see REORDER_DEPENDENCIES).

generate-readmes
    Generate READMEs, rc scripts and login.conf.d files from ${PKGDIR} into ${WRKINST}. Run after fake and before package or update-plist. Always rerun, as it is cheap enough.

index
    Top-level target, see ports(7).

install-depends
    Before package installation, install and verify dependencies constructed from RUN_DEPENDS, LIB_DEPENDS, and WANTLIB.

install
    Install the package after building. See the description of THE FAKE FRAMEWORK for the non-intuitive details of the way {pre,do,post}-install hooks are actually used by the ports tree.

install-all
    Install all packages in a multi-packages port.

lib-depends-args
    Filter LIB_DEPENDS to keep only entries required by WANTLIB, and output a list of dependencies suitable for pkg_create(1), see print-package-args.

lib-depends-check
    Verify that the LIB_DEPENDS and WANTLIB are accurate for the port. See port-lib-depends-check, which is quicker.

license-check
    Check that PERMIT_PACKAGE_* settings match: if any dependency has a more restrictive setting, warn about it. This warning is advisory, because the automated license checking cannot figure out which ports were used only for building and did not taint the current port.

lock
    Manually obtain a lock on a given directory. Output must be used to update environment variables. The lock can be released with unlock. Seldom used, see ports(7) for details.

makesum
    Run sha256(1) on ${MAKESUMFILES} that is, files listed in ${DISTFILES}, ${SUPDISTFILES} and ${PATCHFILES}, and store the result in ${CHECKSUM_FILE}, normally distinfo. Also store the lengths of all files for a quick check during fetch.

no-lib-depends-args
    Degenerate form of lib-depends-args that does not do anything. See print-package-args.

no-wantlib-args
    Degenerate form of wantlib-args that does not do anything. See print-package-args.

package
    Build a port package (or packages in a MULTI_PACKAGES case) from the fake installation. Involves creating packaging information from templates (see COMMENT, SUBST_VARS among others) and invoking pkg_create(1) for each package in the MULTI_PACKAGES list. If the repository already contains up-to-date packages, they are not rebuilt. If PLIST_REPOSITORY is set, the resulting packaging information is compared with existing stuff, and saved if new, with loud complaints if it changed without a REVISION bump. Arch-independent packages are created in ${PACKAGE_REPOSITORY}/no-arch, and copied into ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/all as needed. If ${PERMIT_PACKAGE} is set to ‘Yes’, copies built packages into ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/ftp, using hard links if possible.

patch
    Apply distribution and OpenBSD specific patches. Because of historical accident, patch does not follow the exact same scheme other standard targets do. Namely, patch invokes pre-patch (if defined), do-patch, and post-patch, but the default do-patch target invokes distpatch directly. So, if the do-patch target is overridden, it should still begin by calling ‘make distpatch’, before applying OpenBSD specific patches. Accordingly, the exact sequence of hooks is: pre-patch, do-distpatch, post-distpatch, do-patch, post-patch. If ${PATCHDIR} exists, the files described under PATCH_LIST will be applied under WRKDIST.

peek-ftp
    Connect to the first site in MASTER_SITES, in the right directory, and leaves user at ftp(1)'s prompt.

pkglocatedb
    Top-level target, see ports(7).

port-lib-depends-check
    Verify that the LIB_DEPENDS and WANTLIB hold all shared libraries used for every package in the port. See library-specs(7). This makes use of print-plist-with-depends to avoid actually building the packages, it only needs the completion of the fake stage, and thus is quicker than lib-depends-check, unless you already have all binary packages.

port-wantlib-args
    Resolve WANTLIB against the ports tree itself and system libraries, without looking at built or installed packages, and writes a list of options suitable for pkg_create(1). See print-package-args.

prepare
    Before port building, install and verify dependencies constructed from BUILD_DEPENDS, LIB_DEPENDS and WANTLIB. In MULTI_PACKAGES setups, see FLAVORS AND MULTI_PACKAGES.

print-package-args
    Print all dependency-related information that will be passed as parameters to pkg_create(1), e.g., -W wantlib and -P depends lines.

    Those parameters are generated by run-depends-args for RUN_DEPENDENCIES handling, a form of lib-depends-args for LIB_DEPENDS and WANTLIB interaction, and a form of wantlib-args for WANTLIB resolution.

    Variables lib_depends_args and wantlib_args control the exact behavior: lib_depends_args is normally set to lib-depends-args, but will be set to all-lib-depends-args by port-lib-depends-check, in order to have access to the full list of LIB_DEPENDS for figuring out missing WANTLIB. wantlib_args is normally set to wantlib-args but it may be set to port-wantlib-args for introspection purposes, to fake-wantlib-args to avoid some checks, or to no-wantlib-args to avoid expensive WANTLIB checks entirely.

print-update-signature
    Print the update signature, as computed using information from the ports tree, in the same format used for pkg_info(1) -S.

print-plist
    Generate and print a package packing-list from the static information present in the port.

print-plist-all
    Iterate over print-plist for all subpackages in a given port.

print-plist-all-with-depends
    Iterate over print-plist-with-depends for all subpackages in a given port.

print-plist-contents
    Generate and print package contents from the static information present in the port. In contrast with print-plist, the package contents only consists of files, all tagged with category markers such as @file. See pkg_create(1).

print-plist-libs
    Generate and print the list of static and dynamic libraries present in the port. See pkg_create(1).

print-plist-libs-with-depends
    Like print-plist-libs, but slower. It also handles LIB_DEPENDS, RUN_DEPENDS, and WANTLIB, so that the packing-list has complete dependency information.

print-plist-with-depends
    Like print-plist, but slower. It also handles LIB_DEPENDS, RUN_DEPENDS, and WANTLIB, so that the packing-list is complete.

rebuild
    Force rebuild of the port.

regen
    Force rebuilding configure scripts using gen steps.

reinstall
    Force reinstallation of a port, by first cleaning the old installation. Seldom needed, as update will often do the right thing.

repackage
    Rebuild the packages of a port after removing existing packages.

run-depends-args
    Process RUN_DEPENDS and outputs a list of dependencies suitable for pkg_create(1), see print-package-args.

reprepare
    Force running the prepare target again.

retest
    Force running the test target again.

show
    Invoked as make show=name, show the contents of ${name}. Invoked as make show="name1 name2 ...", show the contents of ${name1} ${name2} ..., one variable value per line. Mostly used from recursive makes, or to know the contents of another port's variables without guessing wrongly.

show-debug-info
    Displays the information that was generated by build-debug-info(1).

show-fake-size
    Print the size of ${WRKINST}, in kilobytes. Used by some options of dpb(1), suitable for BULK_TARGETS.

show-indexed
    Similar to show. Invoked as make show-indexed=name, show the contents of ${name${SUBPACKAGE}}, or ${name} if the variable name is not SUBPACKAGE dependent.

show-list
    Similar to show. Shows "list-like" variables, one entry per line. Mostly useful as a debugging target, since some internal variables may now exceed ARG_MAX.

show-prepare-results
    Print the list of actual installed packages found out by prepare.

show-prepare-test-results
    Print the list of actual installed packages found out by prepare and test-depends.

show-required-by
    Print the list of pkgpath(7) for all ports that will be affected by the current port changing. Works by walking the list of dependencies, in reverse.

show-run-depends
    Print all running dependencies for a port, one per-line, without duplicates.

subpackage
    Build a port package. Exactly like package, but affects only one single subpackage in multi-packages ports.

show-size
    Print the size of the work directory, in kilobytes. Used by some options of dpb(1), suitable for BULK_TARGETS.

subupdate
    Update an existing installation to a newer package, exactly like update, but affects only one single subpackage in multi-packages ports.

test
    Run regression tests for the port. Essentially depend on a correct build and invoke

        env -i ${ALL_TEST_ENV} ${MAKE_PROGRAM} ${ALL_TEST_FLAGS} \
        	-f ${MAKE_FILE} ${TEST_TARGET} ${TEST_LOG}

    If a port needs some other ports installed to run regression tests, use TEST_DEPENDS. If a port needs special configuration or build options to enable regression testing, define a ‘test’ FLAVOR.

test-depends
    Before running regression tests, Install and verify dependencies constructed from TEST_DEPENDS.

unlock
    Manually release a lock on a given directory. See lock.

update-patches
    Create or update patches for a port, using update-patches(1). See EDIT_PATCHES.

update
    Update an existing installation to a newer package: scan the installation for a package with the same FULLPKGPATH, and update it using ‘pkg_add -r’ if a newer package is available. In multi-packages ports, all relevant packages are updated. See UPDATE_COOKIES_DIR and FORCE_UPDATE as well.

update-or-install
    Update an installed package or perform a fresh installation, by using ‘pkg_add -r’. Handles one single package in multi-packages ports. See UPDATE_COOKIES_DIR and FORCE_UPDATE as well.

update-or-install-all
    Update installed packages or perform a fresh installation, by using ‘pkg_add -r’. Handles all packages in multi-packages ports. See UPDATE_COOKIES_DIR and FORCE_UPDATE as well.

update-plist
    Update the packing-lists for a port, using the fake installation and the existing packing lists, by invoking update-plist(1) with the correct parameters, along with port-specific options ( UPDATE_PLIST_ARGS) and user settings ( UPDATE_PLIST_OPTS). Also see SUBST_VARS for details about the default handling of variable substitution.

verbose-show
    Similar to show, except that it prefixes each value with the variable name, e.g., VAR=value. Also note that it does not show undefined variables, contrary to show which outputs blank lines for these.

wantlib-args
    Call port-wantlib-args and fake-wantlib-args and compare the results, errors out in case of discrepancies. See print-package-args.

VARIABLES
Note that some variables are marked as ‘User settings’, which means that individual ports should not modify them, and that some variables are marked as ‘read-only’, which means that they shouldn't ever be changed. In a MULTI_PACKAGES setup, some variables have settings specific to a given subpackage. See FLAVORS AND MULTI_PACKAGES.

show
    Invoked as make show=name, show the contents of ${name}. Invoked as make show="name1 name2 ...", show the contents of ${name1} ${name2} ..., one variable value per line.

ALL_FAKE_FLAGS
    Flags passed to ${MAKE} invocations during the fake process. Equals ${MAKE_FLAGS} ${DESTDIRNAME}=${WRKINST} ${FAKE_FLAGS}. Read-only.

ALL_TEST_ENV
    Environment passed to test. Equals ${MAKE_ENV} ${TEST_ENV}. Read-only.

ALL_TEST_FLAGS
    Flags passed to ${MAKE} invocations during test. Equals ${MAKE_FLAGS} ${TEST_FLAGS}. Read-only.

ALL_TARGET
    Target used to build software. Default is ‘all’. Can be set to empty, to yield a package's default target.

APM_ARCHS
    Set to the list of apm(4) architectures. Read-only. Use with ONLY_FOR_ARCHS.

ARCH
    Current machine architecture. Read-only.

AUTOCONF
    Location of the autoconf binary if needed. Defaults to autoconf.

AUTOCONF_DIR
    Where to invoke autoconf or autoreconf if ${CONFIGURE_STYLE} includes ‘autoconf’ or ‘autoreconf’, respectively. Defaults to ${WRKSRC}.

AUTOCONF_ENV
    Environment values that should be passed to all runs of autoconf, automake and related tools. Specifically, version numbers and PATH. Automatically set as soon as CONFIGURE_STYLE is gnu or higher.

AUTOCONF_VERSION
    Starting with OpenBSD 3.3, several versions of autoconf may coexist peacefully. The main autoconf script is a shell wrapper in the devel/metaauto package, and similarly for automake. Setting AUTOCONF_VERSION along with CONFIGURE_STYLE set to autoconf is the correct way to specify which one to use. AUTOCONF_VERSION defaults to 2.13. If autoconf must be run manually, MODGNU_AUTOCONF_DEPENDS can be used to specify what packages to depend upon.

AUTOHEADER
    Location of the autoheader binary. Defaults to autoheader.

AUTOMAKE_VERSION
    Several versions of automake may coexist peacefully. AUTOMAKE_VERSION must be set before trying to run automake. Defaults to 1.4.

AUTORECONF
    Location of the autoreconf binary and the arguments it is invoked with. Can be set to ‘autogen.sh’ if such a script is available. Defaults to autoreconf --force --install.

BASE_PKGPATH
    Full pkgpath(7) to the current port, taking flavors into account. See also BUILD_PKGPATH, which also includes pseudo-flavors. Read-only.

BASELOCALSTATEDIR
    User settings. Base location for system-wide state directory. Defaults to ${VARBASE}. See LOCALSTATEDIR.

BASESYSCONFDIR
    User settings. Base location for system-wide configuration files. Defaults to /etc. See SYSCONFDIR.

BATCH
    User settings. Set to ‘Yes’ to avoid ports that require user-interaction. Use in conjunction with INTERACTIVE to simplify bulk-package builds. (See IGNORE).

BE_ARCHS
    Set to the list of big-endian architectures. Read-only. Use with NOT_FOR_ARCHS and ONLY_FOR_ARCHS.

BUILD_DEPENDS
    List of other ports the current port needs to build correctly. Each item has the form ‘[pkgspec:]pkgpath[:target]’. ‘target’ defaults to ‘install’. The package installed must conform to the ‘pkgspec’, which is by default obtained from the dependent ‘pkgpath’ ( see PKGSPEC). If no installation is involved, the infrastructure will still check that the directory would provide a package conforming to the ‘pkgspec’. ‘pkgpath’ is set relative to ${PORTSDIR}, see pkgpath(7) for details. Build dependencies are checked before the extract stage during prepare.

    Build dependencies with a patch, configure or build target will be processed in a subdirectory of the working directory, specifically, in ${WRKDIR}/some/directory, with some/directory the directory part of the ‘pkgpath’.

BUILD_ONCE
    User settings. Defaults to ‘’. Set to ‘Yes’ during bulk builds.

    When BUILD_ONCE is set to ‘Yes’, all PSEUDO_FLAVORS matching ‘no_*’ will be disabled, unless the special pseudo-flavor ‘bootstrap’ is also set.

    This is a bulk build optimisation, automatically set by dpb(1): to avoid rebuilding the same package several times, a full bulk build will strip most ports of pseudo-packages variations that remove subpackages.

    For instance, an individual package may depend on databases/db/v4,no_java,no_tcl, to avoid bringing a jdk in during a quick build. Nevertheless, during a full bulk build, databases/db/v4 will only be built once, as the pseudo-flavor will be automatically removed.

    However, the extra ‘bootstrap’ rule is needed to take build cycles into account. For instance, the x11/gnome/gvfs,-goa subpackage depends on gnome-online-accounts, which in turn requires x11/gnome/gvfs,-main to build (through its dependencies). So x11/gnome/gvfs has PSEUDO_FLAVORS = no_smb no_goa bootstrap and the GNOME build first builds x11/gnome/gvfs,no_smb,no_goa,bootstrap,-main which is later used to rebuild x11/gnome/gvfs.

BUILD_PKGPATH
    Full pkgpath(7) to the current port, taking flavors and pseudo-flavors into account. See also BASE_PKGPATH, which doesn't include pseudo-flavors. Mostly useful to write dependencies for subpackages like this: LIB_DEPENDS-foo=${BUILD_PKGPATH} and avoid starting to build a package with some other flavor combination. See pkgpath(7) on the subject of ‘pkgpath normalisation’. Read-only.

BUILD_PACKAGES
    The actual list of packages that will be built, once architecture problems and pseudo-flavors have been taken into account. See FLAVORS AND MULTI_PACKAGES.

BROKEN
    Define only for broken ports, set to reason the port is broken. See also NO_IGNORE, TRY_BROKEN.

BUILD_USER
    User to switch to when using PORTS_PRIVSEP, defaults to ‘_pbuild’.

BROKEN-<arch>
    Define only for ports broken on a given architecture. Distinct from ONLY_FOR_ARCHS and NOT_FOR_ARCHS, which are used to mark ports for which support for some architectures does not exist at all, or is completely obsolete.

BSD_INSTALL_{PROGRAM,SCRIPT,DATA,MAN}[_DIR]
    Macros passed to make and configure invocations. Set based on corresponding INSTALL_* variables.

BULK
    User settings. If set to ‘Yes’, all successful package builds and installations will clean their working directories, after invoking any targets mentioned in BULK_TARGETS, and commands mentioned in BULK_DO. Can be set on a per-${PKGPATH} basis. For instance, setting BULK_misc/screen=No will override any BULK=Yes passed on the command line. If set to ‘Auto’, it will apply to dependencies, but not to the current port itself. See BULK_COOKIES_DIR. Defaults to ‘Auto’.

BULK_COOKIES_DIR
    User settings. Used to store cookies for successful bulk-package builds, defaults to ${PORTSDIR}/bulk/${MACHINE_ARCH}.

BULK_DO
    Commands to run after each bulk package build before cleaning up the working directory. Empty defaults. Can be set on a per-${PKGPATH} basis, e.g., BULK_DO_${PKGPATH}=...

BULK_FLAGS
    Flags to pass to build each target in BULK_TARGETS.

BULK_TARGETS
    Targets to run after each bulk package build before cleaning up the working directory. Empty defaults. Can be set on a per-${PKGPATH} basis, e.g., BULK_TARGETS_${PKGPATH}=...

BZIP2
    Name of the bzip2 binary.

CATEGORIES
    List of descriptive categories into which this port falls. Mandatory. One entry must match the current pkgpath: devel/gmake must belong to the ‘devel’ category. See link-categories, unlink-categories.

CCACHE_DIR
    Sets the cache directory used when USE_CCACHE is set to yes. Defaults to ${WRKOBJDIR}/.ccache.

CCACHE_ENV
    Sets additional environment variables when USE_CCACHE is set to yes. For instance, to enable verbose logging, set CCACHE_ENV="CCACHE_LOGFILE=/tmp/ccache.log"

CDIAGFLAGS
    Flags appended to CFLAGS if WARNINGS is set.

CFLAGS
    Default flags passed to the compiler for building. Many ports ignore it. See also COPTS, CDIAGFLAGS.

CHECK_LIB_DEPENDS
    User settings. If set to ‘Yes’, every package build will verify that shared libraries are correctly registered. This is essentially the same as running ‘make lib-depends-check’ after each package build. Defaults to ‘’, as this can be a big performance hit.

CHECKSUMFILES
    List of all files that need to be retrieved by fetch, with DIST_SUBDIR prepended and with the master site selection extension removed. Read-only. See also MAKESUMFILES.

CHECKSUM_FILE
    Location for this port's checksums, used by checksum, and makesum. Defaults to distinfo.

CHECKSUM_PACKAGES
    User settings. Choose whether or not to checksum packages while building. Deposits result in ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/cksums/${FULLPKGNAME}.sha256. Can be set to ‘Yes’ to compute a checksum for all packages, or to ‘ftp’ to compute it only for PERMIT_PACKAGE packages. Defaults to ‘no’, which does not compute a checksum at all.

CHOSEN_COMPILER
    Read-only. Compiler suite chosen by the COMPILER mechanism. Set to ‘irrelevant’ to disable COMPILER.

CLEANDEPENDS
    If set to ‘Yes’, the clean target will also clean dependencies. Can be overridden on a per-${PKGPATH} basis, by setting CLEANDEPENDS_${PKGPATH}.

COMMENT
    Short (no more than 60 characters) description of the port, used for the package and the INDEX. It should not start with an uppercase letter unless semantically significant.

COMMENT-foo
    Same as COMMENT but used for sub package -foo in a multi-package setup.

COMMENT-vanilla
    Same as COMMENT but used for a flavored package, if the non-flavored comment is inappropriate.

COMMENT-foo-vanilla
    Same as COMMENT but used for a sub-, flavored package.

COMES_WITH
    The first release where the port was made part of the standard distribution. If the current OpenBSD version is >= this version then a notice will be displayed instead of the port being built.

COMPILER
    Select preferred compiler. First element in the list that matches will be chosen.

    base-gcc
        gcc 4.2 compiler from base

    base-clang
        clang compiler from base

    gcc3
        gcc 3 compiler from base

    ports-gcc
        gcc 8 compiler from ports (heeds MODGCC4_ARCHS from the module)

    ports-clang
        clang compiler from ports (heeds MODCLANG_ARCHS from the module)

    The first compiler that matches criteria will be chosen. On clang-based architectures, even though gcc is still compiled in base, ‘base-gcc’ never matches.

    Defaults to base compilers, e.g., ‘base-clang base-gcc gcc3’.

    Common reasons for explicitly setting COMPILER will most often be C++11 support, thread-local-storage support (emulated), atomic operations on some arches, sometimes assembler support, ABI compatibility with dependent/depending ports, or plain old internal compiler errors.

    With COMPILER in effect, MODGCC4_ARCHS and MODCLANG_ARCHS default to ‘${GCC49_ARCHS}’ and ‘${LLVM_ARCHS}’ respectively.

    ONLY_FOR_ARCHS will also be set if applicable.

COMPILER_LANGS
    The value of COMPILER_LANGS will be added to the respective module's supported langs. Defaults to ‘c c++’. Only ‘c’ and ‘c++’ are supported by this mechanism. ‘fortran’ or ‘java’ still need old modules annotations, so that it's possible to select, e.g., ‘gfortran’ from gcc 8 while having clang from base. See also CHOSEN_COMPILER.

COMPILER_LINKS
    Used by bsd.port.mk and compiler MODULES to build scripts in ${WRKDIR}/bin to force setting compiler flags ( -B is required for clang to find ${WRKDIR}/bin/ld as used by USE_WXNEEDED) and call COMPILER_WRAPPER if used.

COMPILER_WRAPPER
    External program used to "wrap" compilers. Populated automatically by USE_CCACHE or can be set explicitly for other purposes (e.g. distcc).

CONFIG_SITE_LIST
    Used when CONFIGURE_STYLE=gnu, or with MODULES += gnu. List of config.site fragments that will speed up gnu-configure, and prevent it from preferring various gnu programs, unless BUILD_DEPENDS explicitly ask for them. Read-only, available for debugging purposes.

CLANG_ARCHS, GCC3_ARCHS, GCC4_ARCHS
    List of architectures using Clang, GCC 3.3.6 or GCC 4.2.1 as the base compiler. Read-only. Use with NOT_FOR_ARCHS or ONLY_FOR_ARCHS to limit ports to architectures where they compile.

CONFIGURE_ARGS
    Arguments to pass to configure script. Defaults are empty, except for GNU-style configure, where prefix and sysconfdir are set.

CONFIGURE_ENV
    Basic environment passed to configure script (path and libtool setup). GNU-style configure adds a lot more variables.

CONFIGURE_SCRIPT
    Set to name of script invoked by the configure target, if appropriate. Should be either an absolute path, or relative to ${WRKSRC}.

CONFIGURE_STYLE
    Set to style of configuration that needs to happen.

    If ‘perl’, assume perl(1)'s ExtUtils::MakeMaker(3p) style. Add ‘modbuild’ to enable Module::Build(3p), ‘modbuild tiny’ to enable Module::Build::Tiny(3p), or ‘modinst’ for Module::Install(3p) style.

    If ‘gnu’, assume GNU configure style. Add ‘dest’ if port does not handle DESTDIR correctly, and needs to be configured to add DESTDIR to prefixes ( see also DESTDIRNAME). Add ‘old’ if port is an older autoconf port that does not recognize --sysconfdir. Add ‘autoconf’ if autoconf needs to be rerun first, but set ‘no-autoheader’ to prevent autoheader from running. Alternatively, add ‘autoreconf’ to rerun autoconf, automake, and related tools to completely regenerate the GNU build framework.

    If ‘imake’, assume port configures using X11 ports Imakefile framework. Add ‘noman’ if port has no man pages the Imakefile should try installing.

    If ‘simple’, there is a configure script, but it does not fit the normal GNU configure conventions.

    Extensions may be defined by specific MODULES. See port-modules(5) for details.

COPTS
    User settings. Supplementary options appended to ${CFLAGS} for building. Since most ports ignore the COPTS convention, they are actually told to use ${CFLAGS} ${COPTS} as CFLAGS.

CXXDIAGFLAGS
    Flags appended to CXXFLAGS if WARNINGS is set.

CXXFLAGS
    Default flags passed to the C++ compiler for building. Many ports ignore it.

CXXOPTS
    User settings. Supplementary options appended to ${CXXFLAGS} for building.

DEBUG_CONFIGURE_ARGS
    Supplementary ${CONFIGURE_ARGS} for enabling the generation of debugging information.

DEBUG_PACKAGES
    List of ${SUBPACKAGES} for which debug packages should be built "on the side". Usually set as DEBUG_PACKAGES=${BUILD_PACKAGES} for packages where debug information is desirable. Note the subpackages with PKG_ARCH=* will automatically be stripped from that list. See THE DEBUG_PACKAGES INFRASTRUCTURE below for details.

DEBUGINFO_ARCHS
    List of archs for which debug information may be provided as extra packages. Normally only amd64 for performance reasons.

DESTDIR
    See DESTDIRNAME.

DESTDIRNAME
    Name of variable to set to ${WRKINST} while faking. Usually DESTDIR. To be used in the rare cases where a port heeds DESTDIR in a few directories and needs to be configured with ‘gnu dest’, so that those few directories do not get in the way.

DISTDIR
    User settings. Directory where all ports distribution files and patchfiles are stashed. Defaults to ${PORTSDIR}/distfiles. Override if distribution files are stored elsewhere. Always use FULLDISTDIR to refer to ports' distribution files location, as it takes an eventual DIST_SUBDIR into account.

DISTFILES
    The main port's distribution files (the actual software source, except for binary-only ports). Will be retrieved from the MASTER_SITES (see fetch), checksummed and extracted (see checksum, extract). DISTFILES normally holds a list of files, possibly with ‘:0’ to ‘:9’ appended to select a different MASTER_SITES.

    Each entry may optionally be of the form ‘filename{url}sufx’ to deal with sites that only offer archives as weird urls, doing the transfer of urlsufx into result file filenamesufx. For instance, if

        DISTFILES = minetest-{minetest/archive/}${V}${EXTRACT_SUFX}

    then fetch will retrieve from url ‘minetest/archive/${V}${EXTRACT_SUFX}’ into ‘minetest-${V}${EXTRACT_SUFX}’.

    If ${DISTFILES} varies depending on FLAVORS or architecture, use SUPDISTFILES to ensure distfiles mirroring and makesum proper operation.

DISTNAME
    Name used to identify the port. See DISTFILES and PKGNAME.

DISTORIG
    Suffix used by distpatch to rename original files. Defaults to .bak.orig. Distinct from .orig to avoid confusing update-patches.

DIST_SUBDIR
    Optional subdirectory of ${DISTDIR} where the current port's distribution files and patchfiles will be located. See target fetch.

DPB Set by the Distributed Ports Builder to only get the information it needs from dump-vars.

DPB_LOCKNAME
    If set, dpb(1) will use this instead of the default PKGPATH- derived name. This feature comes with large restrictions and shouldn't be used unless absolutely necessary. Specifically, it can allow dpb to build several flavors of the same port at the same time, but beware: under MULTI_PACKAGES and PSEUDO_FLAVORS conditions, if some of these packages are identical across flavors, this will not work. This also makes it harder to interact with locks if the names are not obvious.

DPB_PROPERTIES
    Annotations for the Distributed Ports Builder. See dpb(1) for semantics.

DUMMY_PACKAGE
    If defined, bsd.port.mk will provide dummy values for variables mandatory for a minimally functional port. Used by various pieces of the ports tree to perform introspection and get to bsd.port.mk's variables.

ECHO_MSG
    User settings. Used to display ‘===> Configuring for foo’ and similar informative messages. Override to turn off, for instance.

ECHO_REORDER
    User settings. Set it to ‘echo’ to see REORDER_DEPENDENCIES actions. Silent by default.

EDIT_PATCHES
    User settings. If set to ‘’, update-patches will not open changed files in an editor.

EPOCH
    Epoch number of the current package. Used when the port version is changed but the new version is not regarded by packages-specs(7) as being newer. Once added, it cannot be removed or go backwards. Defaults to empty (no need for numbering changes), then numbering starts at 0. Gets automatically incorporated into FULLPKGNAME as ‘v${EPOCH}’ to form a full package-name conforming to packages-specs(7).

ERRORS
    List of errors found while parsing the port's Makefile. Display the errors before making any target, and if any error starts with "Fatal":, do not make anything. For instance:

        .if !defined(COMMENT)
        ERRORS+="Fatal: Missing comment"
        .endif

    Porter can add to ERRORS, for instance to flag erroneous combinations of FLAVORS (but see ONLY_FOR_ARCHS NOT_FOR_ARCHS and BROKEN for other common issues).

EXTRACT_CASES
    In the normal extraction stage (when EXTRACT_ONLY is not empty), this is the contents of a sh(1) case conditional, used to extract files. Fragments are automatically appended to extract the following archives and add the relevant compression tool to BUILD_DEPENDS:

    gzip
        tar.gz, tgz
    tar tar
    archivers/bzip2
        tar.bz2, tbz2, tbz
    archivers/xz
        tar.xz, tar.lzma
    archivers/lzip/lunzip
        tar.lz
    archivers/unzip
        zip
    archivers/zstd
        tar.zst, tar.zstd
    converters/rpm2cpio
        rpm

    Other cases not supported directly in bsd.port.mk can be added, and existing cases can be overridden. For example the following example sets extra conversion flags to unzip, and adds support for rar:

        	*.zip) ${UNZIP} -Laq ${FULLDISTDIR}/$$archive -d ${WRKDIR};; \
        	*.rar) ${LOCALBASE}/bin/unrar x -idq ${DISTDIR}/$$archive;;

EXTRACT_ONLY
    Set to the list of distfiles to actually extract if some distfiles should not be extracted during the do-extract stage. Defaults to all distfiles, can even be set to empty.

EXTRACT_SUFX
    Used to set DISTFILES default value to ${DISTNAME}${EXTRACT_SUFX}. The decompression tool needed will be automatically added as BUILD_DEPENDS. Default value is .tar.gz.

EXTRACT_FILES
    Set to the list of files to actually extract from distfiles. Its content is subject to shell evaluation as part of EXTRACT_CASES and passed as file ... argument to tar(1) or unzip(1), e.g., glob(7) patterns and shell brace expansion may be used. Empty by default to extract all files.

FAKE_FLAGS
    Extra flags passed to ${MAKE_PROGRAM} during the fake invocation. Empty by default. Also see ALL_FAKE_FLAGS.

FAKE_SETUP
    List of environment values normally set during fake invocations. Exposed so that modules may provide their own do-install. Read-only, see THE FAKE FRAMEWORK section for details.

FAKE_TARGET
    Target built by ${MAKE_PROGRAM} on fake invocation. Defaults to ${INSTALL_TARGET}.

FAKEOBJDIR
    User settings. If non empty, used as a base for the fake area. The real fake directory ${WRKINST} is created there. Can be set on a per-${PKGPATH} basis. For instance, setting FAKEOBJDIR_www/mozilla-firefox=/tmp/obj will affect only the mozilla-firefox port.

FETCH_CMD
    User settings. Command used to fetch distribution files for this port. Defaults to ftp(1). Can be used to go through excessively paranoid firewalls. Note that FETCH_CMD should support a few ftp options, chief among them being -C and -o dest, but also -m, -S, -v, -V. Most of these can be no-ops in a FETCH_CMD script, See ${PORTSDIR}/infrastructure/template/fetch_cmd.template for a skeleton script.

FETCH_MANUALLY
    Some ports' distfiles cannot be fetched automatically for licensing reasons. In this case, set FETCH_MANUALLY to a list of strings that will be displayed, one per line, e.g.,

        FETCH_MANUALLY= "You must fetch foo-1.0.tgz"
        FETCH_MANUALLY+="from http://www.fubar.com/ manually,"
        FETCH_MANUALLY+="after reading and agreeing to the license."

    Behaves like IS_INTERACTIVE if some distribution files are missing.

FETCH_PACKAGES
    User settings, defaults to ‘’. Set to pkg_add(1) options. Instruct the package target to download packages missing from the repository from locations in ${PKG_PATH} and place them into ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/cache/, only building them if no suitable packages are found. For instance,

        make FETCH_PACKAGES=

    to use without any options, or

        make FETCH_PACKAGES=-Dsnap

    to use close to release.

FILESDIR
    Location of other files related to the current port. Default: files.

FETCH_USER
    User to use to fetch distfiles when using PORTS_PRIVSEP, defaults to ‘_pfetch’.

FIX_CLEANUP_PERMISSIONS
    If ‘Yes’, restore read, write and directory search permissions for the build user on ${WRKDIR} before running clean. Used for build systems which set paranoid permissions at build time. Defaults to ‘’.

FIX_CRLF_FILES
    Name(s) of files with line endings to correct at the end of distpatch. Sometimes a port will include files with MS-DOS line endings (CR LF). To avoid problems with patches (especially when sent by email) these should be converted to LF. bsd.port.mk changes to WRKDIST before converting files - shell wildcards may be used.

FIX_EXTRACT_PERMISSIONS
    If ‘Yes’, restore contents of ${WRKDIR} to world-readable at the end of extract. Used for some distfile contents which have paranoid permissions for no reason. Defaults to ‘’.

FLAVOR
    The port's current options. Set by the user, and tested by the port to activate wanted functionalities.

FLAVORS
    List of all flavors keywords a port may match. Used to sort FLAVOR into a canonical order to build the package name, or to select the packing-list, and as a quick validity check. See also PSEUDO_FLAVORS.

FLAVOR_EXT
    Canonical list of flavors being set for the current build, dash-separated. See FULLPKGNAME.

FORCE_UPDATE
    User settings. If set to ‘Yes’, the update target will always update an installed package, as soon as its signature differs, and all dependencies that install packages will also force an update. If set to ‘hard’, the update target will also update installed packages even when the signature did not change.

FULLDISTDIR
    Complete path to directory where ${DISTFILES} and ${PATCHFILES} will be located, to be used in hand-crafted extraction targets. Read-only.

FULLPKGNAME
    Full name of the created package, taking flavors into account. Defaults to ${PKGNAME}${FLAVOR_EXT}. See also EPOCH and REVISION.

FULLPKGPATH
    Path to the current port's directory, relative to ${PORTSDIR}, including flavors and subpackages. See pkgpath(7).

GH_*
    Support for GitHub-hosted projects. Leave empty for non hosted projects. Yields a suitable default for MASTER_SITES_GITHUB and DISTNAME.

GH_ACCOUNT
    Account name of the GitHub user hosting the project.

GH_COMMIT
    SHA1 commit id to fetch. It is an error to specify ${GH_COMMIT} when ${GH_TAGNAME} is specified.

GH_DISTFILE
    Set by bsd.port.mk to the generated name of the distribution file. This can be useful for ports listing multiple DISTFILES.

GH_PROJECT
    Name of the project on GitHub.

GH_TAGNAME
    Name of the tag to download. Setting ${GH_TAGNAME} to master is invalid and will throw an error. ${WRKDIST} is auto-generated based on the ${GH_TAGNAME} if specified, otherwise ${GH_COMMIT} will be used to generate ${WRKDIST}.

GMAKE
    Location of the GNU make binary, if needed. Defaults to gmake.

HOMEPAGE
    URL to the homepage of the software, if applicable.

IGNORE
    For ignored ports, set to the reasons for which the port is ignored. If non-empty, most common targets that do something (e.g., fetch, build, install ...) will be ignored. See also BATCH, BROKEN, FETCH_MANUALLY, IGNORE_IS_FATAL, IGNORE_SILENT, INTERACTIVE, IS_INTERACTIVE, NOT_FOR_ARCHS, NO_IGNORE, ONLY_FOR_ARCHS.

IGNORE_IS_FATAL
    User settings. If set to ‘Yes’, ignored ports will become fatal errors.

IGNORE_SILENT
    User settings. If set to ‘Yes’, do not print anything when ignoring a port.

INSTALL_DEBUG_PACKAGES
    User settings. Defaults to ‘’. If ‘Yes’, install available debug packages during all install/update targets.

INSTALL_{PROGRAM,SCRIPT,DATA,MAN}[_DIR]
    Macros to use to install a program, a script, data, or a man page (or the corresponding directory), respectively.

INSTALL_TARGET
    Target invoked to install the software, during fake installation. Default is ‘install’.

INTERACTIVE
    User settings. Set to ‘Yes’ to skip all non-interactive ports. Used in conjunction with BATCH to simplify bulk-package builds.

IS_INTERACTIVE
    Set to ‘Yes’ if port needs human interaction to build. Porters should strive to minimize IS_INTERACTIVE ports, by using FLAVORS for multiple choice ports, and by postponing human intervention to package installation time.

LE_ARCHS
    Set to the list of little-endian architectures. Read-only. Use with NOT_FOR_ARCHS and ONLY_FOR_ARCHS.

LIB_DEPENDS
    List of packages used by a port for its library dependencies. Each item has the form ‘[pkgspec:]pkgpath’. Similar to BUILD_DEPENDS and RUN_DEPENDS, but with specific rules: LIB_DEPENDS always turn into BUILD_DEPENDS ( but see FLAVORS AND MULTI PACKAGES).

    LIB_DEPENDS is also used as a run-time dependency, and recorded in the package as such, if any of the libraries mentioned in WANTLIB is a shared library that originates within the dependent port.

    See library-specs(7) for more details.

lib_depends_args
    Controls the behavior of pkg_create(1) related targets, see print-package-args for details.

LIBCXX
    List of standard C++ libraries for the base compiler. Read-only. Use in WANTLIB.

LIBTOOL
    Location of the libtool binary. Default: /usr/bin/libtool.

LIBTOOL_FLAGS
    Arguments to pass to libtool. If USE_LIBTOOL is set, the environment variable LIBTOOL is set to ${LIBTOOL} ${LIBTOOL_FLAGS}.

LLD_EMUL
    As ld.lld(1) does not have a default emulation mode, if it is the linker in-use, LLD_EMUL defaults to the correct option to set the emulation mode; Otherwise, it stays empty. Read-only. Seldom used, as it is only needed to link binary data without using the compiler.

LLVM_ARCHS
    Set to the list of architectures where LLVM/Clang could be used, e.g., via lang/clang port module, see port-modules(5). Read-only. Use with NOT_FOR_ARCHS or ONLY_FOR_ARCHS.

LOCALBASE
    where other ports have already been installed. Default: /usr/local.

LOCALSTATEDIR
    Location for this port's state directory, should always be derived from BASELOCALSTATEDIR, which defaults to /var. Passed to gnu configure scripts.

LOCKDIR
    User settings. Defaults to ${WRKOBJDIR}/locks. If set, points to a local directory common for all instances of concurrent ports builds.

LOCK_CMD
    Expands to a command that will acquire a lock, namely portlock(1). See also ports(7).

LOCK_VERBOSE
    User settings. Defaults to ‘’. Set to ‘Yes’ to show every acquire/release lock operation.

LP64_ARCHS
    Set to the list of 64-bit architectures. Read-only. Use with NOT_FOR_ARCHS.

MAINTAINER
    Email address with full name of the port's maintainer. Defaults to ports@openbsd.org.

MAKE_ENV
    Environment variables passed to make invocations and tests. Sets at least PATH, PREFIX, LOCALBASE, X11BASE, CFLAGS, TRUEPREFIX, DESTDIR, and the BSD_INSTALL_* macros.

MAKE_FLAGS
    Flags used for all make invocations, except for the fake stage, which adds FAKE_FLAGS (see ALL_FAKE_FLAGS) and for the test stage, which adds TEST_FLAGS (see ALL_TEST_FLAGS).

MAKE_FILE
    Name of the Makefile used for ports building. Defaults to Makefile. Used after changing directory to ${WRKBUILD}.

MAKE_JOBS
    Number of jobs to use when building the port, normally passed to MAKE_PROGRAM through PARALLEL_MAKE_FLAGS. Mostly set automatically when DPB_PROPERTIES contains ‘parallel’.

    Note that make(1) still has bugs that may prevent parallel build from working correctly!

MAKE_PROGRAM
    The make program that is used for building the port. Set to ${MAKE} or ${GMAKE} depending on USE_GMAKE. Read-only.

MAKEFILE_LIST
    Introspection variable, see make(1).

MAKESUMFILES
    List of all files that need to be retrieved by fetch-all, with DIST_SUBDIR prepended and with master site selection extension removed. Read-only. See also CHECKSUMFILES.

MASTER_SITE_BACKUP
    User settings. List of sites to try after normal master sites. Normally includes ${MASTER_SITE_OPENBSD} and ${MASTER_SITE_FREEBSD}.

MASTER_SITE_*
    Lists of standard sites to retrieve files from, refer to ${PORTSDIR}/infrastructure/db/network.conf.

MASTER_SITES
    List of primary locations from which distribution files and patchfiles are retrieved. See the fetch target for details. Defaults to ${MASTER_SITES_GITHUB} for GitHub-hosted projects, see GH_*. See ports(7) for user configuration.

MASTER_SITES0, ..., MASTER_SITES9
    Supplementary locations from which distribution files and patchfiles are retrieved.

MESSAGE
    File recorded in the package and displayed during installation. Defaults to ${PKGDIR}/MESSAGE if this file exists. Leave empty if no message is needed.

MISSING_FILES
    When FETCH_MANUALLY is set, MISSING_FILES will contain the list of missing distfiles or patchfiles that need to be fetched manually. Read-only.

MTREE_FILE
    mtree(8) specification used during fake. Replaced by direct use of mkdir(1) now that fake no longer happens as root.

MODGNU_CONFIG_GUESS_DIRS
    If a port uses config.guess outside WRKSRC, the directories containing the other copies must be set here.

MODPERL_ADJ_FILES
    If any files have a Perl shebang line, which needs to be replaced with “#!/usr/bin/perl”, list them in MODPERL_ADJ_FILES. File paths here should be relative to WRKSRC. These files are patched automatically at the end of pre-configure.

MODPERL_BIN_ADJ
    Shell fragment to patch the Perl interpreter path in executable scripts. Used by MODPERL_ADJ_FILES.

MODPERL_BUILD_TARGET
    Normal content of do-build when CONFIGURE_STYLE uses perl. Provided as a separate variable if a port wants to override do-build for its own reasons.

MODPERL_INSTALL_TARGET
    Likewise for do-install.

MODPERL_TEST_TARGET
    Likewise for do-test.

MODPERL_REGEN_PPPORT
    Normally, if ppport.h is present, it will be regenerated using a current version of Devel::PPPort(3p). Set to the filename under ${WRKSRC}, or ‘’ to disable. Defaults to ‘ppport.h’.

MODULES
    External modules mechanism, documented separately. Modules such as ‘imake’ and ‘gnu’ are normally included automatically with the right CONFIGURE_STYLE. Note that it is possible to CONFIGURE_STYLE = simple, MODULES += gnu to just get the effects of CONFIG_SITE and MODGNU_CONFIG_GUESS_DIRS along with the default TEST_TARGET, in case the normal GNU configure script was wrapped in a separate script that takes different arguments. See port-modules(5).

MULTI_PACKAGES
    Set to a list of subpackage extensions for ports that create multiple packages. See FLAVORS AND MULTI_PACKAGES below. Especially read the part about ONLY_FOR_ARCHS when some of the packages only exist for some architectures.

NO_ARCH
    Location for arch-independent packages. Defaults to ‘no-arch’. Normally, packages are generated under ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}, except for packages where PKG_ARCH=*, which end up under ${PACKAGE_REPOSITORY}/${NO_ARCH}.

NOT_FOR_ARCHS
    List of architectures on which this port does not build. See also ONLY_FOR_ARCHS.

NO_BUILD
    Set to ‘Yes’ if port does not need any build stage.

NO_CCACHE
    Set to ‘Yes’ to prevent ccache from being used when building a certain port, even when USE_CCACHE is set.

NO_CHECKSUM
    Set to ‘Yes’ by dpb(1) to avoid checksum entirely, as dpb(1) already deals with checksums internally.

NO_DEPENDS
    User settings. Don't verify build of dependencies. Do not use in any ports Makefile. This is only meant as a user convenience when, e.g., you just want to browse through a given port's source and do not wish to trigger the build of dependencies.

NO_IGNORE
    User settings. If set to ‘Yes’, avoid ignoring a port for the usual reasons. Use, for instance, for fetching all distribution files, or for fixing a broken port. See also IGNORE and TRY_BROKEN.

NO_TEST
    Port does not have any regression tests. Only set to ‘Yes’ for ports with no regression test. It should be left alone for ports with empty regression tests, and for ports with failing tests. That way, if a subsequent update of a port acquires actual regression tests, they will be picked up automatically.

ONLY_FOR_ARCHS
    List of architectures on which this port builds. Can hold both processor-specific information (e.g., powerpc), and more specific model information (e.g., macppc). This is subpackage dependent. Read the corresponding part of FLAVORS AND MULTI_PACKAGES if some subpackages should only be built on some architectures.

OSREV
    Revision number of OpenBSD. Read-only.

PACKAGE_REPOSITORY
    User settings. Location for built packages. Defaults to ${PORTSDIR}/packages. See package for details.

PARALLEL_MAKE_FLAGS
    Used when DPB_PROPERTIES contains ‘parallel’. Flags to pass to MAKE_PROGRAM to yield a parallel build. Defaults to -j${MAKE_JOBS}. Mostly set to empty by ports that use other mechanisms for setting the number of jobs.

PARALLEL_MAKE_JOBS
    User settings. Value of MAKE_JOBS to use when building manually a port with DPB_PROPERTIES containing ‘parallel’. Defaults to the number of online cpus.

PATCH
    Command to use to apply all patches. Defaults to /usr/bin/patch.

PATCHORIG
    Suffix used by patch to rename original files, and update-patches to re-generate ${PATCHDIR}/${PATCH_LIST} by looking for files using this suffix. Defaults to .orig. For a port that already contains .orig files in the ${DISTFILES}, set this to something else, such as .pat.orig. See also distpatch, DISTORIG.

PATCH_CASES
    In the normal distpatch stage (when PATCHFILES is not empty), this is the contents of a case statement, used to apply distribution patches. Fragments are automatically appended to handle gzip'ed, bzip'ed and lzip'ed patches, so that the default case is more or less equivalent to the following shell fragment:

        set -e
        cd ${FULLDISTDIR}
        for patchfile in ${_LIST_PATCHFILES}
        do
            case $$patchfile in
        	*.bz2)
        	  bzip2 -dc $$patchfile | ${PATCH} ${PATCH_DIST_ARGS};;
        	*.lz)
        	  lunzip -c $$patchfile | ${PATCH} ${PATCH_DIST_ARGS};;
        	*.Z|*.gz)
        	  gzcat $$patchfile | ${PATCH} ${PATCH_DIST_ARGS};;
        	*)
        	  ${PATCH} ${PATCH_DIST_ARGS} <$$patchfile;;
            esac
        done

PATCHDIR
    Location for patches applied by the patch target. Default: patches.

PATCHFILES
    Files to fetch from the master sites like DISTFILES, but serving a different purpose, as they hold distribution patches that will be applied at the patch stage. See also SUPDISTFILES.

PATCH_ARGS
    Full list of options used while applying port's patches.

PATCH_CHECK_ONLY
    Set to ‘Yes’ by the checkpatch target. Don't touch unless the default checkpatch target needs to be redefined. Ideally, user-defined patch subtargets ought to test checkpatch. In practice, they don't.

PATCH_DEBUG
    If set to ‘Yes’, the patch stage will output extra debug information. This is the default.

PATCH_DIST_ARGS
    Full list of options used while applying distribution patches.

PATCH_DIST_STRIP
    Patch option used to strip directory levels while applying distribution patches. Defaults to -p0.

PATCH_LIST
    Wildcard pattern of patches to select under ${PATCHDIR}. Defaults to patch-*. Note that filenames ending in .orig, or ~ are never applied. Note that PATCH_LIST can hold absolute pathnames, for instance to share patches among similar ports:

        PATCH_LIST=${PORTSDIR}/x11/kde/libs2/patches/p-* patch-*

PATCH_STRIP
    Patch option used to strip directory levels while applying port's patches. Defaults to -p0.

PERMIT_DISTFILES, PERMIT_PACKAGE
    Set to ‘Yes’ if the distribution files or the package can be allowed on FTP sites without legal issues. Set to reason not to otherwise. PERMIT_* lines in the Makefile should be preceded with a comment explaining details about licensing and patents issues the port may have. Porters must be very thorough in their checks. In case of doubt, ask.

    If PERMIT_PACKAGE is set to ‘Yes’, PERMIT_DISTFILES will default to ‘Yes’.

PKG_ADD
    User settings. Path to pkg_add(1) command, with possible options.

PKG_ARCH
    Comma-separated list of architectures on which this package may install. Defaults to ${MACHINE_ARCH},${ARCH}. Use * for arch-independent packages.

PKG_ARGS
    Special arguments to pass to pkg_create(1), in addition to the default ones. For mips64 and pic libraries, see THE GENERATION OF PACKAGE INFORMATION.

PKG_CREATE
    User settings. Path to pkg_create(1) command, with possible options.

PKG_CREATE_NO_CHECKS
    Porters switch. Set to ‘Yes’ to avoid checking the ports tree when solving WANTLIB ( see wantlib-args). May result in bogus packages that mix @depends lines obtained from the ports tree with @wantlib lines that come from the installed system. Set to ‘Warn’ to have the differences printed as a warning instead of an error ( the default).

PKG_DBDIR
    User settings. Path to package installation records. Defaults to /var/db/pkg.

PKG_DELETE
    User settings. Path to pkg_delete(1) command, with possible options.

PKG_INFO
    User settings. Path to pkg_info(1) command, with possible options.

PKG_TMPDIR
    See pkg_add(1). Normally points to /var/tmp, as per default.

PORTHOME
    Setting of env variable HOME for most shell invocations. Default will trip ports that try to write into $HOME while building.

PORTPATH
    Path used by most shell invocations. Don't override unless really needed.

PORTSDIR
    Root of the ports tree (default: /usr/ports).

PORTSDIR_PATH
    Path used by dependencies and bsd.port.subdir.mk to look up package specifications. Defaults to ${PORTSDIR}:${PORTSDIR}/mystuff.

PORTS_PRIVSEP
    If set to ‘Yes’, will build ports as BUILD_USER and fetch distfiles as FETCH_USER.

    To work fully, this does require the ports tree to be world-readable, and ${WRKDIR} to be world-readable as well ( update-patches and friends won't work otherwise).

    Meant to use in concert with dpb(1), which uses the same permissions ( see ‘THE SECURITY MODEL OF DPB’ in dpb(1)).

    Basically, BUILD_USER must be able to write into ${WRKOBJDIR}, ${PACKAGE_REPOSITORY}, ${PLIST_REPOSITORY} and FETCH_USER must be able to write into ${DISTDIR}. The directories and permissions can be set correctly using fix-permissions.

    The regular user must be allowed to execute commands as BUILD_USER and FETCH_USER. Running commands as another user can be achieved with doas(1) by setting SUDO=doas in mk.conf(5) and using the following minimal doas.conf(5):

        permit keepenv nopass solene as _pbuild
        permit keepenv nopass solene as _pfetch

    It is reasonably safe to allow your user id to run commands as the BUILD_USER or FETCH_USER and using nopass for these can save a lot of password entry, however it is inadvisable to allow commands like pkg_add(1) to run as root without a password.

    Note that this also means that doas(1) must be configured to work within the chroot created by proot(1).

    As dpb(1) does its own privilege dropping when run as root, it will automatically override PORTS_PRIVSEP.

    User settings, defaults to ‘’.

PKGDIR
    Location for packaging information (packing-list, port description, messages). update-plist may create it. Must be a valid directory. Default: pkg.

PKGFILE
    Full path to the created package for the given subpackage. Read-only.

PKGFILES
    Full path to all created packages. Read-only.

PKGNAME
    Name of the created package. Default is ${DISTNAME}. This does not take flavors into account. See FULLPKGNAME for that. Specific revisions and epoch changes should be handled by REVISION and EPOCH instead.

PKGNAMES
    Read-only. List of all package names generated by the port, with FLAVORS and BUILD_PACKAGES taken into account. Mostly used as ‘make show=PKGNAMES’ to verify that bumped package names are correct.

PKGNAME-foo
    Package name for sub-package foo, if the default value of ${PKGNAME}${SUBPACKAGE} is not appropriate.

PKGPATH
    Path to the current port's directory, relative to ${PORTSDIR}. Read-only.

PKGPATHS
    Read-only. List of all package paths generated by the port, with FLAVORS and MULTI_PACKAGES taken into account. Order matches PKGNAMES exactly.

PKGSPEC
    Default package spec for using this port as a dependency. Defaults to ‘stem-*’, derived from the FULLPKGNAME. Do not override without very good reasons, namely software that coexist as different incompatible versions with the same stem, e.g., already a mess.

PKGSTEM
    Base for the package name without any version number. Used in READMEs file names and actual contents, can be overridden for ports with branches, like php, e.g., PKGSTEM-main = php-5.6

PLIST_DB
    Deprecated, see PLIST_REPOSITORY.

PLIST_REPOSITORY
    User settings. Base directory used to save generated packing-lists, as persistent information. Packing-lists are processed by a script, register-plist(1), which complains when packing-lists change without a REVISION bump. It also knows enough about package version numbers when something in the package or its dependencies goes backward, thus catching EPOCH issues. This directory is never cleaned during normal operation. ‘make clean=plist’ should only ever be used during debugging by port maintainers. Defaults to ${PORTSDIR}/plist ( plists actually get saved into ${PLIST_REPOSITORY}/${MACHINE_ARCH}). If set to empty, will not register anything: very much unsafe.

PORTS_BUILD_XENOCARA_TOO
    EXPERIMENTAL. Set to ‘Yes’ to build xenocara through ports. This is highly experimental and not recommended.

PORTROACH
    Controls the behavior of misc/portroach as documented in detail at http://jasperla.github.io/portroach/docs/portroach-portconfig.txt.

PREFIX
    Base directory for the current port installation. Usually ${LOCALBASE}, though some ports may elect a location under ${VARBASE}, and some multi-package ports may install under several locations. Additionally, firmware files generally install under ${BASESYSCONFDIR}.

PREPARE_CHECK_ONLY
    Build settings. Prevent the prepare stage from installing anything, let it just check dependencies, and handle [:target] dependencies. Mostly used by dpb(1), which already installs everything before running prepare.

PROGRESS_METER
    User settings. Defaults to ‘Yes’. Forces commands like ftp(1) and pkg_create(1) to use their progress-meter even in the absence of a terminal.

PROPERTIES
    List of properties specific to a given machine architecture. Most often obtained through bsd.port.arch.mk(5). These can be checked like this

        .include <bsd.port.arch.mk>
        .if ${PROPERTIES:Mapm}
        # then add build options specific to apm arches
        ...
        .if !${PROPERTIES:Mlp64}
        # build options specific to lp32 arches
        ...

    For MULTI_PACKAGES setup, use of ONLY_FOR_ARCHS-sub and BUILD_PACKAGES is generally preferred (and simpler). Possible properties include

    apm architecture possesses suspend (apm) support.

    be  architecture is big-endian.

    gccN
        gccN architecture.

    le  architecture is little-endian.

    lp64
        lp64 architecture.

    llvm
        there is lang/llvm support on this architecture.

    mono
        there is lang/mono support on this architecture.

PSEUDO_FLAVOR
    List of flavors in FLAVOR that are actually pseudo-flavors. Only for introspection purposes. Read-only.

PSEUDO_FLAVORS
    Extra list of flavors that do not register in package names, but are still used to control build logic, and work directory names. Its only use should be for disabling part of a multi-packages build, for instance:

        FLAVOR=no_gnome make package

    Pseudo-flavors should be named as ‘no_something’ to disable the build of subpackage ‘-something’ ( and possibly some others, by restricting BUILD_PACKAGES). Pseudo-flavors should always be handled through bsd.port.arch.mk(5). A pseudo-flavor can remove several subpackages through the following construct.

        # pseudo-flavor no_gui will also remove gtk and gtk3
        MULTI_PACKAGES = -main -gtk -gtk3 -gui
        # ...
        .include <bsd.port.arch.mk>
        # remove extra build components
        .if !${BUILD_PACKAGES:M-gui}
        BUILD_PACKAGES := ${BUILD_PACKAGES:N-gtk:N-gtk3}
        .endif
        # normal configure setup, e.g.,
        .if ${BUILD_PACKAGES:M-gtk}
        # ...

    Caveat: creation of a separate working directory is mandatory for a pseudo-flavor. If, at a later time, a full build with all subpackages is required, all the work will need to be done again.

    See also BUILD_ONCE.

RCDIR
    Location for daemon startup scripts. Defaults to /etc/rc.d. Do not change.

REFETCH
    User settings. If set to true, checksum will analyze ${CHECKSUM_FILE}, and try retrieving files with the correct checksum off https://ftp.openbsd.org, in the directory /pub/OpenBSD/distfiles/$cipher/$value/$file.

REGISTER_PLIST_OPTS
    User settings. User options added to register-plist(1).

REORDER_DEPENDENCIES
    Points to a list of files that specify inter-dependencies for make(1). If defined, each line of the file is either a comment (starting with #) or a pair of two files: most_recent older. At the end of post-patch, touch(1) will be used to ensure those files are put in the proper order. The files are assumed to be under ${WRKSRC}. The notation /file can be used to ask for a recursive search, e.g., to make sure that all Makefile.in are up to date. See ${PORTSDIR}/infrastructure/mk/automake.dep for an example.

REPORT_PROBLEM
    See ports(7).

REPORT_PROBLEM_LOGFILE
    See ports(7).

REVISION
    Revision number of the current package. Defaults to empty (very first package), then numbering starts at 0. Gets automatically incorporated into FULLPKGNAME as ‘p${REVISION}’ to form a full package-name conforming to packages-specs(7).

RUN_DEPENDS
    Specification of ports this port needs installed to be functional. Same format as LIB_DEPENDS. The corresponding packages will be built right before the install stage, and pkg_add(1) will take care of installing them.

SEPARATE_BUILD
    Many GNU configure ports can be built in a directory distinct from the place they were unpacked. For some specific ports, this is even mandatory. Set to ‘yes’ if this is the case. The ports infrastructure will generate a separate ${WRKBUILD} directory in which the port will be configured and built. Wipe ${WRKBUILD} to start anew, but skipping the extract/patch stage.

SETENV
    Normally set to /usr/bin/env -i. Prepended to every command invocation that requires a clean environment. Do not override.

SHARED_LIBS
    List of shared libraries that the port may build, as a list of the form ‘libname’ ‘libversion’. Used to set variables of the form LIBlibname_VERSION that are then used for substitution by pkg_create(1). The porter is responsible for making sure the port uses those version numbers when shared libraries are built.

    The intent is that the OpenBSD ports system must have control over shared library versions because of global changes that may require bumping the major version of every shared library in the system, or simply because the third party programmers do not understand the rules for shared library versions, thus breaking the update mechanism. For that reason it is advised to set libversion to 0.0 when first importing a port.

    Porters of software using libtool should make sure MAKE_FLAGS get propagated to the libtool invocations. This should be enough in most cases.

SKIPDIR
    See ports(7).

STATIC_PLIST
    Normally set to ‘yes’. Can be set to no for ports that do not have a static plist. Do not change without a very good reason. Note that the only good reason to not have a static plist is for ports such as databases/ports-readmes which actually build a bunch of files depending on the current ports tree. This breaks all introspection mechanisms within the ports tree, including databases/pkglocatedb which will not include that port.

STARTAFTER
    See ports(7).

STARTDIR
    See ports(7).

SUBPACKAGE
    Set to the subpackage suffix when building a package in a multi-package port. Read-only. Used to test for dependencies or to adjust the package name.

SUBST_CMD
    A command that can be used to perform SUBST_VARS substitution on arbitrary files. In normal mode,

        ${SUBST_CMD} file1 file2 ...

    will substitute files in place, creating backup copies of them. In copy mode,

        ${SUBST_CMD} -c src1 dest1 src2 dest2

    will copy files over while performing the substitution, as suitable for copying template files over from ${FILESDIR} to ${PREFIX}, for instance. This uses pkg_subst(1) with suitable parameters. Read-only.

    ${SUBST_CMD} can be used like install(1):
        ${SUBST_CMD} [-g group] [-o owner] [-m mode] file...
    to set file owner, group and/or mode.

    Note that SUBST_CMD is not really appropriate when variables have subpackage variations, like PREFIX or FULLPKGNAME. Use the appropriate SUBST_CMD-sub instead.

SUBST_CMD-sub
    SUBST_CMD with subpackage-dependent semantics, like packing-list substitution. It will substitute the right variable depending on the desired subpackage, e.g., SUBST_CMD-foo will substitute the value of FULLPKGNAME-foo for ${FULLPKGNAME}.

SUBST_DATA, SUBST_MAN, SUBST_PROGRAM
    Specialized versions of SUBST_CMD that use -c and appropriate owner/group/mode for data, manpages and programs respectively.

SUBST_VARS
    Make variables whose values get substituted to create the actual package information. Always holds ARCH, BASE_PKGPATH, FLAVOR_EXT, FULLPKGNAME, HOMEPAGE, LOCALBASE, MACHINE_ARCH, MAINTAINER, PREFIX, PKGSTEM, RCDIR, SYSCONFDIR, TRUEPREFIX, and X11BASE. The special construct ‘${FLAVORS}’ can be used in the packing-list to specify the current list of dash separated flavors the port is compiled with (useful for cross-dependencies in MULTI_PACKAGES). Add other variables as needed.

    TRUEPREFIX is never passed to pkg_create(1) as it is identical to PREFIX.

    By default, update-plist(1) is run with the following options:

        update-plist -i ARCH -i BASE_PKGPATH -i FULLPKGNAME
        -i FULLPKGPATH -i LOCALSTATEDIR -i MACHINE_ARCH
        -s BASE_PKGPATH -s LOCALBASE -s LOCALSTATEDIR -s PREFIX
        -s RCDIR -s SYSCONFDIR -s X11BASE

SUDO
    User settings. If set to doas(1) in mk.conf(5), the ports tree will only invoke root's privileges for the parts that really require it.

SUPDISTFILES
    Supplementary files that need to be retrieved under some specific circumstances. For instance, a port might need architecture-specific files. SUPDISTFILES should hold a list of all distribution files and patchfiles that are not always needed, so that a mirror will be able to grab all files, or that makesum will work. Having an overlap between SUPDISTFILES and DISTFILES, PATCHFILES is admissible, and in fact, expected, as it is much simpler to build an error-free list of files to retrieve in that way. See the xanim port for an example.

SYSCONFDIR
    Location for this port's configuration files, should always be derived from BASESYSCONFDIR, which defaults to /etc. Passed to gnu configure scripts and substituted in packing-lists.

TAR Name of the tar binary.

TARGETS
    Read-only. Set to the list of special targets for a port ( {pre,do,post}-* and module hooks). Used by introspection tools such as the sqlports package.

TEMPLATES
    Base location for the templates used in the readmes target. User settings. Defaults to ${PORTSDIR}/infrastructure/templates.

TEST_DEPENDS
    See BUILD_DEPENDS for specification. Test dependencies are only checked if the test stage is invoked.

TEST_ENV
    Additional environment variables passed to tests. Empty by default.

TEST_FLAGS
    Extra flags passed to ${MAKE_PROGRAM} to run the regression tests. Empty by default.

TEST_IS_INTERACTIVE
    Set to ‘Yes’ if port needs human interaction to run its tests, or set to ‘X11’ if the tests need an active X11 display to work.

TEST_LOG
    Command used to log the results of regression tests to TEST_LOGFILE. Read-only.

TEST_LOGFILE
    Log file containing the results of regression tests.

TEST_TARGET
    Target to run regression tests. Defaults to ‘regress’, except for ‘perl’ and ‘gnu’ CONFIGURE_STYLE, which default to ‘test’ and ‘check’, respectively.

TRUEPREFIX
    Read-only. Mostly the same as ${PREFIX}, except it never gets ${DESTDIR} prepended during fake. Refer to THE FAKE FRAMEWORK section for details.

TRY_BROKEN
    User settings. If set to ‘Yes’, don't set IGNORE for BROKEN ports, so that we will attempt to build them.

UNLOCK_CMD
    User settings. If set, expands to a command that will release a lock. This lock will reside in ${LOCKDIR}.

UNMESSAGE
    File recorded in the package and displayed during deinstallation. Defaults to ${PKGDIR}/UNMESSAGE if this file exists. Leave empty if no message is needed.

UNZIP
    Name of the unzip binary.

UPDATE_COOKIES_DIR
    User settings. Used to store cookies for package updates and defaults to ${PORTSDIR}/update/${MACHINE_ARCH}. If set to empty, will revert to a file under ${WRKDIR}.

UPDATE_PLIST_ARGS
    Tweaks to update-plist(1) behavior for some specific ports, such as variable handling.

UPDATE_PLIST_OPTS
    User settings. User options added to update-plist(1), mostly -v for now.

USE_CCACHE
    User settings. Set to ‘Yes’ to use ccache when building ports. Sets up the build environment so that it is used.

USE_GMAKE
    Set to ‘Yes’ if GNU make (${GMAKE}) is needed for correct behavior of this port.

USE_GROFF
    Set to ‘Yes’ to use groff to build manpages. This sets groff as a build dependency, and also tells pkg_create(1) to format manpages behind the scene using groff while building packages.

USE_LIBTOOL
    Defaults to ‘Yes’. Set to ‘gnu’ if the base libtool(1) is insufficient and GNU libtool is required. Set to ‘’ to disable the use of libtool(1) entirely; this should not be set under normal circumstances. Adds dependencies if necessary, and passes LIBTOOL environment variable to scripts invocations.

    Many ports using GNU autoconf need an m4 file from the GNU libtool package but otherwise work with base libtool(1). In those cases do not set USE_LIBTOOL, instead just set BUILD_DEPENDS = devel/libtool.

USE_LLD
    Set to ‘Yes’ or ‘’ to force the use of ld.lld(1) ( as opposed to bfd's ld(1)). Defaults to the appropriate value for the current architecture ( see LLD_ARCHS in bsd.port.arch.mk(5)).

USE_MFS
    Set to ‘Yes’ to build ports under an MFS filesystem (see mount_mfs(8)). Mostly for use by dpb(1) and not intended to be a user setting. See WRKOBJDIR_MFS for configuration.

USE_WXNEEDED
    If set to ‘Yes’, writes a wrapper script to ${WRKDIR}/bin/ld in patch to request that the linker adds an PT_OPENBSD_WXNEEDED ELF section. Use when a port requires memory mappings that are both executable and writable and cannot be modified to avoid this.

USE_X11
    Normally, presence of ${X11BASE} is enforced by default for building ports. But there is an experimental way to hook the xenocara build into dpb(1), which requires knowing whether a port requires X11 to already be there.

    The infrastructure mostly sets USE_X11 automatically based on WANTLIB values, there are a few ports (about 20) that require X11 components without any library telltale.

VARBASE
    User settings. Base location for ports that install stuff outside of ${LOCALBASE}. Defaults to /var.

WANTLIB
    List of library specifications that a package will need. May include system and X11 libraries. See library-specs(7) for more details.

    As a special extension, WANTLIB may include absolute paths, e.g., ${LOCALBASE}/lib/expat=4 to distinguish between base libraries and port libraries. Use with caution, this is very seldom needed.

wantlib_args
    Controls the behavior of pkg_create(1) related targets, see print-package-args for details.

WARNINGS
    User settings. If set to ‘Yes’, add CDIAGFLAGS to CFLAGS and CXXDIAGFLAGS to CXXFLAGS.

WRKBUILD
    Subdirectory of ${WRKDIR} where the actual build occurs. Defaults to ${WRKSRC}, unless SEPARATE_BUILD is involved, in which case it is set to an appropriate value.

WRKCONF
    Subdirectory of ${WRKDIR} where the actual configure set occurs. Defaults to ${WRKBUILD}.

WRKDIR
    Location where all port activity occurs. Apart from the actual port, may hold all kinds of cookies that checkpoint the port's build. Read-only. Note that WRKDIR may be a symbolic link. During ports building, ${WRKDIR}/bin is put at the front of the PATH.

WRKDIR_LINKNAME
    Name of a symbolic link to create within the port directory which will point to the port's ${WRKDIR}. Deprecated.

WRKDIST
    Subdirectory of ${WRKDIR} in which the distribution files normally unpack. Base for all patches. Defaults to ${WRKDIR}/${DISTNAME}. Note that WRKDIST may be a symbolic link, if set to ${WRKDIR}.

WRKSRC
    Subdirectory of ${WRKDIR} where the actual source is. Base for configuration (default: ${WRKDIST}). Note that WRKSRC may be a symbolic link, if set to ${WRKDIR}.

WRKINST
    Subdirectory of ${WRKDIR} where port normally installs (see the fake target).

WRKOBJDIR
    Used as a base for the actual port working directory. Defaults to ${PORTSDIR}/pobj. The real working directory ${WRKDIR} is created there. Can be set on a per-${PKGPATH} basis. For instance, setting WRKOBJDIR_www/mozilla=/tmp/obj will affect only the mozilla port. If explicitly unset (WRKOBJDIR=), the working directory is created within the port directory.

WRKOBJDIR_MFS
    Alternate location for the port working directory. The intent is to use an MFS based filesystem for small ports with dpb(1). Active when USE_MFS is ‘Yes’. Defaults to /tmp/pobj.

X11BASE
    Where X11 has been installed. Default: /usr/X11R6.

XAUTHORITY
    Points to a suitable authority file for X11 interactive regression tests. Defaults to ${HOME}/.Xauthority.

XMKMF
    Invocation of xmkmf for a CONFIGURE_STYLE=imake port. Defaults to xmkmf -a -DPorts. The -DPorts is specific to OpenBSD and is always appended.

YACC
    Name of yacc program to pass to GNU-configure, defaults to yacc. GNU-configure would always try to use bison otherwise, which leads to unreproducible builds. Set to bison if needed.

DIAGNOSTICS
Note that some of these messages are actually emitted by some other external commands, but grouped here for convenience: easier to look for in dpb(1)'s logs.

/bin/sh: cd .../pkg - No such file or directory Emitted during generate-readmes. ${PKGDIR} must point to an existing directory, so that bsd.port.mk can be certain there are no MESSAGEs or other files pertinent to the package.

Discovered old directory in ... This message comes from update-plist(1). A directory was found in the packing-list file mentioned in the diagnostic. That directory line used to be needed but is no longer, because it's now accounted for through dependencies. Indicates the old directory has been removed.

Error: change in plist between ... Error message comes from register-plist(1).

Error: duplicate item in packing-list Error message comes from pkg_create(1), and will result from incorrect packing-lists, such as including several fragments with the same file, or having incorrect PKG_ARGS-sub.

Error: Libraries in packing-lists...and libraries from installed packages don't match The ports tree and the installed packages are out-of-sync. Mixing library information from both sources might produce packages that can't be installed elsewhere. Cleanest fix is to update the out-of-date source (e.g., update the ports tree, or build and install new packages). Developers may use PKG_CREATE_NO_CHECKS instead, assuming they understand the implications. See print-package-args (wantlib-args) for details.

Fatal: can't flavor a SUBDIR A dependency mentions top_subdir,flavor. Flavor would then be ignored, as it is only applied to individual ports.

Fatal: can't subpackage a SUBDIR A dependency mentions top_subdir,-sub. Subpackage would then be ignored, as it is only applied to individual ports.

Fatal: flavor should never start with a digit This would utterly confuse pkg_add(1). See packages-specs(7).

Fatal: inclusion of <file> from <file> bsd.port.mk or bsd.port.subdir.mk has been included from a MODULE or from Makefile.inc, resulting in a double inclusion. This would lead to weird results, such as PKG_ARGS being defined twice.

Fatal: SUBPACKAGES should always begin with -: <offending list> That is the only way to differentiate between FLAVOR and SUBPACKAGE in pkgpath(7) specifications.

Fatal: building ports requires correctly installed X11 All file sets of the base OS, including xenocara, must be installed before building ports.

Fatal: /usr/local/lib/X11/app-defaults should exist and be a symlink /usr/local/lib/X11/app-defaults is distributed as a symlink in the xshare*.tgz file set. If xenocara was not fully installed before packages were added, it may have been created as a directory instead.

Fatal: the licensing info for <pkgname> is incomplete... Every port must have explicit defines of all PERMIT_* values.

Fatal: Use 'env FLAVOR=flavor make' instead Arguments specified after make(1) are hardcoded for all recursive sub-makes, and very difficult to override. Thus, FLAVOR must be specified in the environment instead.

Fatal: Use 'env SUBPACKAGE=-sub make' instead Arguments specified after make(1) are hardcoded for all recursive sub-makes, and very difficult to override. Thus, SUBPACKAGE must be specified in the environment instead.

ldconfig: <dir>: No such file or directory Usually produced by pkg_add(1) running ldconfig(8). Some tools such as GNU libtool will add directories living under ${WRKINST} to the shared library path during the fake stage. Of course, ldconfig(8) will later complain after the directory no longer exists. The bogus tool should be fixed to conform to OpenBSD usage.

LIB_DEPENDS <spec> not needed for <FULLPKGPATH> There doesn't seem to be any WANTLIB to match the given LIB_DEPENDS. Thus, the LIB_DEPENDS won't turn into a @depends line in the created package. This is often because of confusion between LIB_DEPENDS and RUN_DEPENDS: RUN_DEPENDS is needed for dlopen'd libraries.

Might be intentional sometimes, if some compile flavors create static binaries, for instance. Also, will happen for multi-packages, where one sets LIB_DEPENDS to have a given build dependency (and corresponding WANTLIB for a given SUBPACKAGE).

See print-package-args (lib-depends-args) for details.

Warning: FULLPKGNAME-sub defined but not FULLPKGPATH-sub FULLPKGNAME-sub has been explicitly defined by the port, instead of relying on the default, but no value of FULLPKGPATH-sub has been given. This is often an error.

Warning: no debug-info in ... Port uses DEBUG_PACKAGES so the build-debug-info(1) script expects debug information on all binaries and libraries. Most probably, the build machinery for that specific port omitted -g somewhere, or it runs strips during fake anyway. It can also occur if DEBUG_PACKAGES includes subpackages with no files holding debug info.

Warning: symlink(s) point to non existent file. Warning message comes from pkg_create(1). The symlink resides in the fake area, under ${WRKINST}. This is only a warning because the symlink may point to a run-time dependency, which obviously won't exist under ${WRKINST} at the time ‘make package’ is run.

Warning: @option no-default-conflict with no @conflict Warning message comes from pkg_create(1). Most packages that waive "default-conflict" will have explicit conflict markers instead. Otherwise, the package will only conflict with the exact same version, with some possible REVISION bumps. Any other version or FLAVOR won't conflict. This is generally an error, apart from very few ports like devel/autoconf/*.

groff produced empty result for <manpage>... Warning message comes from pkg_create(1). Manpages are automatically formatted with groff(1) if USE_GROFF is set. The above message denotes an actual problem while formatting the page, which should be addressed. In the meantime, pkg_create(1) still produces a package, but leaves the manpage unformatted, in the hope that something will be able to make sense of it.

FILES

../Makefile.inc
    Common Makefile fragment for a set of ports, included automatically.

/cdrom/distfiles
    Default path to a CD-ROM (or other media) full of distribution files.

${PORTSDIR}/distfiles
    Default setup of ${DISTDIR}.

${DISTDIR}
    Cache of all distribution files.

distinfo
    Checksum file. Holds the output of cksum(1), using sha256(1) for the port's ${DISTFILES} and ${PATCHFILES}, as well as the sizes of these files.

    Extra directory used to store local ports before committing them. All depend targets will normally look there after the normal lookup fails. See PORTSDIR_PATH.

THE FAKE FRAMEWORK
The fake target is used to install the port in a private directory first, ready for packaging by the package target, so that the actual installation will use the package.

Essentially, fake invokes a real install process after tweaking a few variables.

fake first creates a skeleton tree under ${WRKINST}, using mkdir(1) -p.

A pre-fake target may be used to complete that skeleton tree. For instance, a few ports may need supplementary stuff to be present (as it would be installed if the port's dependencies were present).

If {pre,do,post}-install overrides are present, they are used with some important changes, listed in FAKE_SETUP:

    TRUEPREFIX=${PREFIX}
    PREFIX=${WRKINST}${PREFIX}
    ${DESTDIRNAME}=${WRKINST}

Essentially, old install targets work transparently, except for a need to change PREFIX to TRUEPREFIX for symbolic links and similar path lookups. Specific traditional post install work can be simply removed, as it will be taken care of by the package itself (for instance, ldconfig, or texinfo's install-info).

If no do-install override is present, the port is installed using

    env -i ${MAKE_ENV} ${FAKE_SETUP} ${MAKE_PROGRAM} ${ALL_FAKE_FLAGS} -f ${MAKE_FILE} ${FAKE_TARGET}

Note that this does set both PREFIX and ${DESTDIRNAME}. If a port's Makefile both heeds ${DESTDIRNAME}, and references PREFIX explicitly, FAKE_FLAGS may rectify the problem by setting PREFIX=${PREFIX} (which will do the right thing, since ${PREFIX} is a make(1) construct which will not be seen by the shell).

${FAKE_FLAGS} is used to set variables on make(1) command line, which will override the port Makefile contents. Thus, a port that mentions DESTDIR= does not need any patch to work with fake.

Files such as ${PKGDIR}/README* or ${PKGDIR}/*.rc get copied to ${WRKINST} right after the end of fake, during generate-readmes (see the FILES section above for details).

THE DEBUG_PACKAGES INFRASTRUCTURE
If DEBUG_PACKAGES is not empty, debug packages will be built "on the side". Since debug information is usually large, this is controlled on a per-arch basis with DEBUGINFO_ARCHS controlling the behavior (set to amd64 by default).

During the normal package target , build-debug-info(1) will be invoked to deduce debug packing-lists from the normal packing-lists, and some extra makefile rules will be invoked to set aside the debug information.

Then each normal package will have a "shadow" debug-* package built alongside it, with the exact same package signature, except it will also be tied closely with the normal package.

Figuring out what files contain debug information is entirely achieved through @bin, @lib, @so and @static-lib annotations in the base packing-lists.

Debug packages will be produced for all subpackages in DEBUG_PACKAGES. Usually, the heuristics of trimming arch-independent packages from BUILD_PACKAGES is enough. In case this still produces empty debug packages, the DEBUG_PACKAGES list should be produced manually.

The actual debug packages are not registered through register-plist(1) since the information was automatically generated.

debug package names and debug package filenames are added to PKGNAMES and PKGFILES respectively for introspection purpose.

egdb(1) from ports can read debug information from a separate file, as long as the original ELF file was annotated with a debuginfo link.

That feature is used to set debug information on the side, in .debug/ subdirectories alongside the normal binaries, shared objects and shared libraries.

For static libraries, the information can't be separated, instead the full static library with debug information is provided in the .debug/ subdirectory, while the normal static library gets stripped.

FLAVORS AND MULTI_PACKAGES
Starting with OpenBSD 2.7, each port can generate distinct packages through two orthogonal mechanisms: FLAVORS and MULTI_PACKAGES.

The current MULTI_PACKAGES mechanism was introduced after OpenBSD 4.0.

The arch-dependent part was refined after OpenBSD 5.0.

If a port can be compiled with several options, these options should be turned into FLAVORS. The port maintainer will set FLAVORS to be the list of possible options in the Makefile. When building the port, the package builder will set FLAVOR='option1 option2...' to build a specific flavor of the port. The Makefile should test the value of FLAVOR as follows:

    FLAVOR?=
    .if ${FLAVOR:Moption1}
    # what to do if option1
    .endif
    .if ${FLAVOR:Moption2}
    # what to do if option2
    .endif

bsd.port.mk takes care of a few details, such as generating a distinct work directory for each flavor, or creating a FULLPKGNAME by adding a dash separated list of flavors to the base package name. The order in which FLAVOR is specified does not matter: this dash separated list will be reordered to match the ordering of FLAVORS.

It is an error to specify an option in FLAVOR that does not appear in FLAVORS, to prevent misspellings.

In bulk package building, flavors can be specified as a comma separated list after the package directory, e.g., SUBDIR+=vim,no_x11 ( see pkgpath(7))

Finally, package information will use templates with the canonical package extension if they are available: if FLAVOR='option1 option2' and both COMMENT and COMMENT-option1-option2 are available, COMMENT-option1-option2 will be used.

If one build of a port can generate several distinct packages, set MULTI_PACKAGES accordingly. Each extension of a MULTI_PACKAGES name should start with a dash, so that they cannot be confused with FLAVORS. In dependency checking and bulk builds, a subpackage can be specified after a comma, e.g., SUBDIR+=quake,-server. MULTI_PACKAGES only affects the actual package building step.

If MULTI_PACKAGES is set, the packaging stage happens once for every subpackage, using subpackage-specific variables. For instance, if MULTI_PACKAGES=-main -lib -server, PKG_ARCH-main, PKG_ARCH-lib and PKG_ARCH-server will be used for the subpackages respectively called FULLPKGNAME-main, FULLPKGNAME-lib and FULLPKGNAME-server.

All package information is also derived from templates with SUBPACKAGE appended. In the preceding example, the packing-list template for FULLPKGNAME-lib must be in PLIST-lib.

The following variables are subpackage dependent: COMMENT, PKG_ARCH, PERMIT_PACKAGE, PKGFILE, PKGNAME, PKGSTEM, FULLPKGNAME, REVISION, EPOCH, FULLPKGPATH, RUN_DEPENDS, WANTLIB, LIB_DEPENDS, IGNORE, ONLY_FOR_ARCHS, NOT_FOR_ARCHS, PKG_ARGS, PREFIX, CATEGORIES, MESSAGE, UNMESSAGE, DESCR, PLIST, STATIC_PLIST, PKGSPEC.

The usual non-MULTI_PACKAGES variables are simply used as default values for all subpackages. So, if you set PKG_ARCH=* PKG_ARCH-main=i386 then PKG_ARCH-lib and PKG_ARCH-server will both be ‘*’.

WANTLIB and LIB_DEPENDS are special. At the beginning of the build, during prepare, all build dependencies will be checked, which includes LIB_DEPENDS, WANTLIB for every subpackage. As an exception, any LIB_DEPENDS-sub that references the current port will be ignored as a build dependency, in order to avoid recursion.

FULLPKGPATH and FULLPKGNAME are special as well. If PKGNAME is <stem>-<version>, then PKGNAME-sub will be set to <stem>-sub-<version> by default, except for PKGNAME-main which has PKGNAME as a default. Normally, FULLPKGPATH-sub is automatically set to the right value, but in very rare cases, one may need to override the default: for instance, if one specific subpackage is not affected by flavor settings that affect other subpackages, e.g., for include files packs, then the flavoring part of the fullpkgpath may need to be dropped.

In terms of using the port, quite a few targets will have a subpackage specific subtarget: invoking package is the same as invoking subpackage for all subpackages, invoking install-all is the same as invoking install for all subpackages, and invoking update is the same as invoking subupdate for all subpackages.

ONLY_FOR_ARCHS and NOT_FOR_ARCHS interact with MULTI_PACKAGES and IGNORE. The infrastructure will automatically filter subpackages that are not suitable for the current architecture. Thus, MULTI_PACKAGES should always list all subpackages, even things not buildable on the current architecture, for indexing purposes.

Starting with OpenBSD 5.1, bsd.port.arch.mk(5) should be used to simplify the handling of MULTI_PACKAGES in arch-dependent setups:

Make sure MULTI_PACKAGES, ONLY_FOR_ARCHS*, and PSEUDO_FLAVORS are defined correctly, then

    .include <bsd.port.arch.mk>

This will compute BUILD_PACKAGES, the list of actual subpackages to build with the current setup, by taking arch constraints and pseudo-flavors into account. Then test BUILD_PACKAGES to set up the right configuration, e.g., to check if SUBPACKAGE -mono should be built:

    .if ${BUILD_PACKAGES:M-mono}

The lang/gcc/8 or print/poppler ports should provide examples of proper use.

Note that dpb(1) will break if all subpackages are not properly listed.

THE GENERATION OF PACKAGE INFORMATION
Starting after OpenBSD 4.1 all package information is processed directly by pkg_create(1) from templates in ${PKG_DIR}.

•   If not overridden by the user, determine which set of templates to use, depending on the current SUBPACKAGE and FLAVOR information. Set PLIST${SUBPACKAGE}, DESCR${SUBPACKAGE}, COMMENT${SUBPACKAGE}, MESSAGE${SUBPACKAGE}, UNMESSAGE${SUBPACKAGE} accordingly.
•   Generate the actual DESCR, and if needed, MESSAGE, UNMESSAGE, from the templates in ${DESCR}, ${MESSAGE}, ${UNMESSAGE}, by substituting the variables in ${SUBST_VARS}, and by substituting ${FLAVORS} with the canonical flavor extension for this port, e.g., if FLAVORS=no_map gfx qt2, if FLAVOR=gfx no_map, this is ‘-no_map-gfx’.
•   Generate the actual packing-list from the template ${PLIST}, by inserting fragments and applying the same variable substitutions as other package information.

Note that ${COMMENT} is currently not substituted.

To avoid substitution, variables can be escaped as follows: $\{PREFIX}

If FLAVORS lists flv, then constructs such as the line %%flv%% or !%%flv%% in the packing-list template trigger the inclusion of ${PKGDIR}/PFRAG.flv${SUBPACKAGE} or ${PKGDIR}/PFRAG.no-flv${SUBPACKAGE}. Other fragments can be defined by simply adding -Dfrag=1 or -Dfrag=0 to PKG_ARGS.

If libraries are built using bsd.lib.mk, special care should be taken for mips64* architectures, which do not ever build *pic.a files (all mips code is pic already). bsd.port.mk automatically adds -Dno_mips64=1 or -Dno_mips64=0 to PKG_ARGS, and the porter only needs to provide the appropriate fragment.

pkg_add(1) now calls ldconfig(8) directly, provided dynamic libraries have been annotated with @lib libthingy.so.5.0. Adding new directories to the dynamic loader cache has been deprecated. It is often better to let libraries be visible as a link under ${LOCALBASE}. Having a separate directory is enough to trick ld(1) into grabbing the right version. Libraries used only for dlopen(3) do not need to be visible. Some programs will prefer to use rpath to find their own libraries.

The special update-plist target does a fairly good job of automatically generating the packing-list information.

If PLIST_REPOSITORY points to a directory, all packing-lists from packages generated by pkg_create(1) during the package stage are saved in ${PLIST_REPOSITORY}/${MACHINE_ARCH} by a script: ${PORTSDIR}/infrastructure/bin/register-plist. This script strips some irrelevant information and normalizes the packing-list somehow, and compares it to existing information, looking for relevant changes. Since a package name must always be changed when the packing-list changes, any attempt to replace a packing-list of a given name with a different packing-list will be flagged as an error.

In MULTI_PACKAGES mode, there must be separate COMMENT, DESCR, and PLIST templates for each SUBPACKAGE (and optional distinct MESSAGE, UNMESSAGE files in a similar way). This contrasts with the FLAVORS situation, where all these files will automatically default to the non-flavor version if there is no flavor-specific file around.

OBSOLETE TARGETS

addsum
    Used for direct fiddling with distinfo, made obsolete by the correct use of SUPDISTFILES.

cdrom-packages, ftp-packages
    Links are now created during the package target.

depends-list
    Renamed into full-build-depends.

describe
    Printed a one-line index entry of the port. dump-vars provides much more accurate information, and the indexing role has been taken over by the sqlports and portslist packages.

{build,run,lib}-depends
    The dependency mechanism now meshes BUILD_DEPENDS, LIB_DEPENDS, RUN_DEPENDS, WANTLIB and MULTI_PACKAGES. Refer to prepare, install-depends, test-depends.

{pre,do}-extract
    Don't override. Set EXTRACT_ONLY to nothing and override post-extract instead.

{pre,do,post}-fetch
    These prevented bulk mechanisms from running properly.

{pre,do,post}-package
    There is no port that requires special treatment during packaging, as {pre,do,post}-install should take care of every necessity.

fetch-list, mirror-distfiles, fetch-makefile, mirror-maker, mirror-maker-fetch
    Use dpb -F instead, see mirroring-ports(7).

obj Starting with OpenBSD 3.3, using WRKOBJDIR no longer creates a symlink between the current directory and a subdirectory of ${WRKOBJDIR}, so obj is no longer applicable.

print-depends
    Use print-build-depends and print-run-depends instead.

print-depends-list
    Renamed into print-build-depends.

print-package-depends
    Renamed into print-run-depends.

print-package-signature
    Renamed into print-update-signature.

readme, readmes
    replaced by the databases/ports-readmes port, using the Template Toolkit ( textproc/p5-Template) instead of hand-coded substitutions.

OBSOLETE VARIABLES

BIN_PACKAGES
    Old user settings. The infrastructure always trusts the repository to contain correct packages. So, if the package name did not change and if it exists in the repository, it will not be rebuilt without manual user action.

CATn
    List of formatted manpages, per section.

CATPREFIX
    Location for storing formatted manpages. Derived directly from PREFIX.

CDROM_PACKAGES
    Old user settings. Base location where packages suitable for a CD-ROM would be placed.

COMMENT
    Used to be the name of the comment file for a package. It now holds the comment itself. Some magic has been put in to allow for a seamless transition.

CONFIGURE_SHARED
    Used to default to --enable-shared or --disable-shared, depending on whether the architecture supported shared libraries.

DESCR_SRC
    From NetBSD. This is DESCR. OpenBSD does not give a specific name to the generated file. It is not recommended to try to access it directly.

EXTRACT_AFTER_ARGS
    Was used to cobble together the normal extraction command, as ${EXTRACT_CMD} ${EXTRACT_BEFORE_ARGS} ${EXTRACT_AFTER_ARGS}. Use EXTRACT_CASES instead.

EXTRACT_BEFORE_ARGS
    Likewise, use EXTRACT_CASES instead.

EXTRACT_CMD
    Likewise, use EXTRACT_CASES instead.

FETCH_BEFORE_ARGS, FETCH_AFTER_ARGS
    Set FETCH_CMD to point to a script that does any required special treatment instead.

FETCH_DEPENDS
    Used to specify dependencies that were needed to fetch files. It is much easier to mirror locally weird distribution files.

FTP_PACKAGES
    User settings. Base location where packages suitable for FTP (see PERMIT_PACKAGE) will be placed. Now hardwired to ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/ftp.

GNU_CONFIGURE
    Use CONFIGURE_STYLE instead.

HAS_CONFIGURE
    Use CONFIGURE_STYLE instead.

IGNOREFILES
    Set to the list of files that can't be checksummed. All uses of it have led to postponing the correct action: talking to the software authors and getting them to provide versioned archives.

MANn
    List of unformatted manpages, per section.

MANPREFIX
    Location for storing unformatted manpages. Derived directly from PREFIX.

MASTERDIR
    From FreeBSD. Used to organize a collection of ports that share most files. OpenBSD uses a single port with flavors or multi-packages to produce package variations instead.

MASTER_SITE_SUBDIR
    Contents were used to replace ‘%SUBDIR%’ in all MASTER_SITES variables. Since ‘%SUBDIR%’ almost always occur at the end of the directory, the simpler ${VARIABLE:=subdir/} construct is now used instead ( taken from NetBSD).

MD5_FILE
    Use CHECKSUM_FILE instead.

MIRROR_DISTFILE
    Use PERMIT_DISTFILES to determine which files can be mirrored instead. See mirroring-ports(7).

NEED_VERSION
    Used to set a requirement on a specific revision of bsd.port.mk needed by a port. No longer needed as bsd.port.mk should always be kept up to date.

NO_CONFIGURE
    If ${CONFIGURE_SCRIPT} does not exist, no automatic configuration will be done anyway.

NO_DESCRIBE
    Describe was killed ages ago.

NO_EXTRACT
    Set EXTRACT_ONLY= instead.

NO_INSTALL_MANPAGES
    Use CONFIGURE_STYLE instead.

NO_MTREE
    Starting with OpenBSD 2.7, the operating system installation script runs the /usr/local specification globally, instead of embedding it in each package. So packages no longer record an mtree(8) specification. Use an explicit ‘@exec’ command if needed.

NO_PACKAGE
    All ports should generate a package, preferably before install.

NO_PATCH
    The absence of a patches directory does the same. Use PATCHDIR and PATCH_LIST if patches need to be changed dynamically.

NO_SHARED_ARCHS
    Used to be set to the list of platforms that did not support shared libraries. No such architectures remain.

NO_SHARED_LIBS
    Used to be set to ‘Yes’ if platform did not support shared libraries.

NO_WRKDIR
    All ports should have a working directory, as this is necessary to store cookies and keep state.

NO_WRKSUBDIR
    The same functionality is obtained by setting WRKDIST=${WRKDIR}.

NOCLEANDEPENDS
    Use CLEANDEPENDS instead.

NOMANCOMPRESS
    FreeBSD ships with compressed man pages, and uses this variable to control that behavior.

OBJMACHINE
    Starting with OpenBSD 3.3, setting WRKOBJDIR creates the whole WRKDIR hierarchy under ${WRKOBJDIR}, so OBJMACHINE is no longer useful.

OLD_WRKDIR_NAME
    Used to be a base name for WRKDIR in the old scheme without WRKOBJDIR.

OPSYS
    The operating system. This ports tree is only used on OpenBSD.

OPSYS_VER
    Use OSREV instead.

PACKAGES
    Base location for packages built, everything is based on PACKAGE_REPOSITORY now.

PACKAGING
    Used to be set during package creation, so that the port would test it to tweak some settings at this point. All its effects are now achieved through MULTI_PACKAGES.

PATCH_SITES
    PATCHFILES used to be retrieved from a separate site list. For greater flexibility, all files are now retrieved from MASTER_SITES, MASTER_SITES0, ..., MASTER_SITES9, using a ‘:0’ to ‘:9’ extension to the file name, e.g.,

        PATCHFILES=foo.diff.gz
        PATCH_SITES=ftp://ftp.zoinx.org/pub/

    becomes

        PATCHFILES=foo.diff.gz:0
        MASTER_SITES0=ftp://ftp.zoinx.org/pub/

PERMIT_DISTFILES_CDROM, PERMIT_DISTFILES_FTP, PERMIT_PACKAGE_CDROM, PERMIT_PACKAGE_FTP
    The OpenBSD project no longer produces CD-ROMs, so the PERMIT_*_CDROM variables were dropped, and PERMIT_DISTFILES_FTP / PERMIT_PACKAGE_FTP were shortened to PERMIT_DISTFILES / PERMIT_PACKAGE.

PKG_CMD
    Replaced by PKG_CREATE.

PKGREPOSITORY
    Old user settings. See PACKAGE_REPOSITORY.

PKGREPOSITORYBASE
    Old user settings. See PACKAGE_REPOSITORY.

PLIST_SRC
    From NetBSD. This is PLIST. OpenBSD does not give a specific name to the generated file. It is not recommended to try to access them directly.

PKGNAME
    Used to refer to the full package name, has been superseded by FULLPKGNAME-foo, for SUBPACKAGE -foo. PKGNAME now holds the package name, not taking multi-packages or flavors into account. Most ports are not concerned by this change.

PLIST_SUBST
    From NetBSD and FreeBSD. Use SUBST_VARS instead. OpenBSD does not allow general substitutions of the form VAR=value, but uses only a list of variables instead. Most package files gets transformed, instead of only the packing-list.

PREFERRED_CIPHERS
    Allowing user change of cryptographic digest is dangerous.

RECURSIVE_FETCH_LIST
    No longer needed with modern mirroring-ports(7).

RESTRICTED
    Port has cryptographic issues. OpenBSD focuses on PERMIT_PACKAGE instead.

SED_PLIST
    Old pipeline for creating packing-lists at the ports level. Necessary functionality has been integrated directly into pkg_create(1).

SIGNING_PARAMETERS
    Old user settings. There is no longer any benefit to signing packages during creation.

SCRIPTDIR
    Old location for scripts related to the current port. There is no reason for the semantic distinction, use FILESDIR for those.

SCRIPTS_ENV
    Used to contain the environment for invoking various scripts. CONFIGURE_ENV and MAKE_ENV are enough.

SHARED_ONLY
    Had to be set to ‘Yes’ if port could only be built on architectures with shared libraries.

USE_AUTOCONF
    Use CONFIGURE_STYLE instead.

USE_BZIP2
    The framework will automatically detect the presence of .tar.bz2 files to extract. See also BZIP2, EXTRACT_CASES, and EXTRACT_SUFX.

USE_IMAKE
    Use CONFIGURE_STYLE instead.

USE_ZIP
    The framework will automatically detect the presence of .zip files to extract. See also ZIP, EXTRACT_CASES, and EXTRACT_SUFX.

VARNAME
    Use make show=name instead of make show VARNAME=name.

WRKPKG
    Directory used to build package information from the templates under ${PKGDIR}. This information is now built on the fly by pkg_create(1).

OBSOLETE FILES

{files,patches,pkg}.${ARCH}
    Offensive to introspection, makes it impossible to build a decent sqlports on a given arch. Hasn't been used for a long time, and there are lots of mechanisms such as PKG_ARGS and fragment substitution, or PATCH_LIST to achieve similar results.

Makefile.${ARCH}
    Likewise, offensive to introspection too.

${FILESDIR}/md5
    Renamed to distinfo to match other BSD, and save directories.

${SCRIPTDIR}/{pre,do,post}-*
    Identical functionality can be obtained through a {pre,do,post}-* target, invoking the script manually if necessary.

${SCRIPTDIR}/configure
    No longer invoked automatically. Just inline the instructions in do-configure in the Makefile, or put the script in ${FILESDIR} and invoke it.

${PKGDIR}/COMMENT
    Use COMMENT variable instead.

${PKGDIR}/DEINSTALL*
    Use @unexec annotations in the packing-list instead.

${PKGDIR}/INSTALL*
    Use @exec annotations in the packing-list instead.

${PKGDIR}/PLIST.{noshared,no-shared,shared}
    Packaging list fragments to handle platforms that did not support shared libraries.

${PKGDIR}/PLIST.sed
    Use PLIST directly. Until revision 1.295, bsd.port.mk did not substitute variables in the packing-list unless this special form was used.

${PKGDIR}/REQ*
    Old requirement script. Was mostly unused anyway.

/usr/share/mk/bsd.port.mk
    Original location of bsd.port.mk. The current file lives under ${PORTSDIR}/infrastructure/mk/bsd.port.mk, whereas /usr/share/mk/bsd.port.mk is just a stub.

{scripts,files,patches}.${OPSYS}
    The OpenBSD ports tree focuses on robustness, not on being portable to other operating systems. In any case, portability should not need to depend on operating system dependent patches.

/usr/local/etc
    Used by FreeBSD to marshall system configuration files. All OpenBSD system configuration files are located in /etc, or in a subdirectory of /etc.

HISTORY
The ports mechanism originally came from FreeBSD. A lot of additions were taken from NetBSD over the seminal years.

Since 1998, the framework has been systematically cleaned-up and reorganized to remove bugs. New features have been carefully introduced, trying hard to avoid inconsistencies.

FLAVORS, MULTI_PACKAGES, SEPARATE_BUILD and FAKE are OpenBSD improvements. Most recent additions do not come from another BSD.

BUGS AND LIMITATIONS
LOCALBASE, X11BASE, BASESYSCONFDIR, VARBASE and PREFIX are not heeded consistently. Using anything but the default values has not been heavily tested. Some ports may not build if you change them.
