BUILD(1)

NAME
build - build SUSE Linux RPMs in a chroot environment

SYNOPSIS
build [--clean|--no-init] [--repo dir_or_url] [--repo...] [--root buildroot] [recipefile]
build --help
build --verify

DESCRIPTION
build is a tool to build binary packages in a safe and reproducible way. The default is to build in a chroot sandbox, but build also supports building in a virtual machine for better security.

If a recipe file is specified on the command line, build will use this file and all other files in the directory for building the package. If no recipe argument is provided, build will search the current directory for a file.

The build tool understands the following recipe file types:

spec
    A specfile used to generate rpms.

src.rpm
    A source rpm, which will be unpacked for the build.

kiwi
    A kiwi config file used to generate a kiwi image.

dsc A dsc file used to generate Debian binary packages.

PKGBUILD
    A file used to generate Arch Linux binary packages.

build.collax
    A shell script used to generate a Collax binary package.

OPTIONS

--clean
    Remove the build system and reinitialize it from scratch.

--no-init
    Skip the build system initialization and start with build immediately.

--repo dir_or_url
    Either a directory containing binary packages (optionally with repository metadata), or a url pointing to some remote repository. Multiple --repo options can be used so create a specific repository layering. Note that packages are searched in the specified repository order, i.e. the first repository containing a package with a specific name wins regardless of the version. As a special form, 'zypp://reponame' can be used to specify a system repository. 'zypp://' selects all enabled system repositories. This is also the default if BUILD_RPMS is not set and no --rpms or --repo option is used.

--dist distribution
    Set the distribution. If this option is not given, build tries to guess the distribution by looking at the available packages. The specified distribution can either be a string like "11.2" or "sles9", "debian7", or the pathname of the build configuration to use.

--root buildroot
    Specifies where the build system is set up. Overrides the BUILD_ROOT enviroment variable.

--help
    Print a short help text.

--norootforbuild
    Force building with user abuild. Otherwise, build searches the recipe file for a "needsrootforbuild" hint to decide what user to use.

--list-state
    list packages that would be used to create a fresh build root. Does not create the build root or perform a build.

--rpms path1:path2:path3...
    Where build can find the packages needed to create the build system. This option overrides the BUILD_RPMS environment variable. This option is deprecated, use --repo instead.

--arch arch1:arch2:arch3...
    What architectures to select from the RPMs. build automatically sets this to a sensible value for your host if you do not specify this option so you should almost never need it.

RPM BUILD SPECIFIC OPTIONS

--useusedforbuild
    Tell build not to do dependency expansion, but to extract the list of packages to install from "# usedforbuild" lines or, if none are found, from all "BuildRequires" lines. This option is useful if you want to re-build a package from a srcrpm with exactly the same packages used for the srcrpm build.

--stage
    Pass a stage option to rpmbuild. The default is -ba.

--target
    Call rpmbuild with a target option. This can be used for cross building.

--verify
    Verify the files in an existing build system.

VIRTUAL MACHINE SPECIFIC OPTIONS

--xen --kvm --uml --qemu --emulator --zvm --lxc
    Sets a specific vm type.

--vm-type type
    As above.

--vm-disk file
    Specifies the location of the disk image to use. If this option is not given, buildroot.img is used (e.g. /var/tmp/build-root.img).

--vm-disk-size size_in_mb
    Specify the size of the disk image to create.

--vm-disk-filesystem type
    Sets the filesystem type to use when creating the disk image. The default is to use the ext3 filesystem.

--vm-swap file
    Specifies the location of the swap file to use. If this option is not given, buildroot.swap is used (e.g. /var/tmp/build-root.swap).

--vm-swap-size size_in_mb
    Specify the size of the swap file to create.

--vm-memory size_in_mb
    Sets the desired memory size of the virtual machine.

--vm-kernel kernel_file
    Set a specific kernel to boot in the virtual machine.

--vm-initrd initrd_file
    Set a specific kernel to boot in the virtual machine.

--vm-disk-clean
    Force the recreation of the disk image.

--vm-telnet PORT
    Is forwarding PORT to a telnet session inside of the VM. Specify also needed extra packages via -x parameter, usually: --vm-telnet 1234 -x telnet-server -x net-tools
       And connect from the host via: telnet localhost 1234
       NOTE: The telnet server gets started after all packages got installed.

RECIPE FILE OPTIONS
The build command interprets some special control comments in the recipe file:

# norootforbuild
# needsrootforbuild
    build uses either user root or user abuild in the build system to do the build. For non-SUSE distros as well as since SUSE 10.2, the default build user is abuild. For 10.2 and before, the default build user is root. These two flags in the spec file allow to deviate from the defaults and force-set the build user to abuild and root (for # norootforbuild and # needsrootforbuild respectively.

# needsbinariesforbuild
    provide the binary rpms that have been used to set up the build root in /.build.binaries within the build root.

ENVIRONMENT

BUILD_ROOT
    The directory where build should install the chrooted build system. "/var/tmp/build-root" is used by default. See the --root option.

BUILD_RPMS
    This can be used instead of the --rpms option. Deprecated.

BUILD_RPM_BUILD_STAGE
    The rpm build stage (-ba, -bb, ...). This is just passed through to rpm, check the rpm manpage for a complete list and descriptions. "-ba" is the default. You should probably use the --stage option instead.
