\`configure' configures GNU roff 1.24.0.rc4 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/groff]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-dependency-tracking
                          do not reject slow dependency extractors
  --disable-dependency-tracking
                          speeds up one-time build
  --enable-silent-rules   less verbose build output (undo: "make V=1")
  --disable-silent-rules  verbose build output (undo: "make V=0")
  --disable-largefile     omit support for large files
  --enable-threads={isoc|posix|isoc+posix|windows}

  --disable-threads       build without multithread safety
  --enable-cross-guesses={conservative|risky}
                          specify policy for cross-compilation guesses
  --disable-rpath         do not hardcode runtime library paths
  --enable-groff-allocator
                          enable libgroff's allocator for C++ new/delete
  --enable-year2038       support timestamps after 2038

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-gnulib-prefix=DIR  search for gnulib's runtime data in DIR/share
  --with-x                use the X Window System
  --with-appdefdir=DIR    place X11 application defaults files in DIR
  --with-uchardet={auto|no|yes}
                          build 'preconv' against uchardet library to
                          automatically detect input file encoding
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-libiconv-prefix[=DIR]  search for libiconv in DIR/include and DIR/lib
  --without-libiconv-prefix     don't search for libiconv in includedir and libdir
  --without-urw-fonts     disable support for URW fonts
  --with-urw-fonts-dir=DIR
                          search for URW PostScript Type 1 fonts in DIR
  --with-compatibility-wrappers={check|manual|no|yes}
                          choose whether and how groff compatibility wrappers
                          for vendor-provided non-GNU macro packages are
                          installed. 'check' searches for such packages, and
                          behaves as if 'yes' or 'no' were given, accordingly.
                          'yes' generates compatibility wrappers for the
                          vendor-provided packages to allow their use with
                          groff and related tools. The compatibility wrappers
                          are installed using the vendor-provided names, while
                          their groff implementations are installed with a 'g'
                          prefix. Use of the latter thus requires options of
                          the form '-mg<package>' (example: -mgan). 'no'
                          installs only the groff implementations. 'manual'
                          generates compatibility wrappers for the
                          vendor-provided packages as '<macro>-os'. Use of the
                          latter thus requires options of the form
                          '-m<macro>-os' option (example: -man-os).
  --with-alt-gs=LIST      alternative names for ghostscript executable
  --with-gs=PROG          actual [/path/]name of ghostscript executable

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  XMKMF       Path to xmkmf, Makefile generator for X Window System
  PKG_CONFIG  path to pkg-config utility
  PKG_CONFIG_PATH
              directories to add to pkg-config's search path
  PKG_CONFIG_LIBDIR
              path overriding pkg-config's built-in search path
  UCHARDET_CFLAGS
              C compiler flags for UCHARDET, overriding pkg-config
  UCHARDET_LIBS
              linker flags for UCHARDET, overriding pkg-config
  CXXCPP      C++ preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

# POSIX will say in a future version that running "rm -f" with no argument

# actually supported "in the wild" to an acceptable degree.
# See automake bug#10828.
# To make any issue more visible, cause the running configure to be aborted

Oops!

Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present.  This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>

Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message.  This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.

You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: <https://www.gnu.org/software/coreutils/>.

If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

/* Thanks to Mike Haertel and Jim Avera for this test.
   Here is a matrix of mmap possibilities:
	mmap private not fixed
	mmap private fixed at somewhere currently unmapped
	mmap private fixed at somewhere already mapped
	mmap shared not fixed
	mmap shared fixed at somewhere currently unmapped
	mmap shared fixed at somewhere already mapped
   For private mappings, we should verify that changes cannot be read()
   back from the file, nor mmap's back from the file at a different
   address.  (There have been systems where private was not correctly
   implemented like the infamous i386 svr4.0, and systems where the
   VM page cache was not coherent with the file system buffer cache
   like early versions of FreeBSD and possibly contemporary NetBSD.)
   For shared mappings, we should conversely verify that changes get
   propagated back to all the places they're supposed to be.

   Grep wants private fixed already mapped.
   The main things grep needs to know about mmap are:
   * does it exist and is it safe to write into the mmap'd area
   * how to use it (BSD variants)  */

  groff font description files for the URW fonts, used by the 'gropdf'
  output driver, will not be available.  Use and embedding of fonts from
  the 'U' foundry in PDF documents generated by groff will not be
  possible.

  You can obtain the URW base 35 fonts from their GitHub project.  As of
  this writing (2023-02-15), you can find them in the 'fonts' directory
  of the following archives (choose one).

  You may wish to check for a newer release.

  'gropdf' looks for these fonts in several directories specified in
  font/devpdf/Foundry.in$gs_verbiage.

  You will need to \"make distclean\" and re-run the 'configure' script
  after installing the URW fonts.

  Alternatively, you can pass the option '--with-urw-fonts-dir=DIR'
  to 'configure' to look for them in the directory DIR you specify.
  If found, the 'U' foundry will be available via the '-y' option to
  'gropdf' (accessed via the 'groff' command with the option '-P -y').
