\`configure' configures GNU Emacs 29.0.90 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]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --disable-ns-self-contained
                          disable self contained build under NeXTstep
  --enable-locallisppath=PATH
                          directories Emacs should search for lisp files
                          specific to this site
  --enable-checking[=LIST]
                          enable expensive checks. With LIST, enable only
                          specific categories of checks. Categories are:
                          all,yes,no. Flags are: stringbytes, stringoverrun,
                          stringfreelist, structs, glyphs
  --enable-profiling      build emacs with low-level, gprof profiling support.
                          Mainly useful for debugging Emacs itself. May not
                          work on all platforms. Stops profiler.el working.
  --enable-autodepend     automatically generate dependencies to .h-files.
                          Requires gcc, enabled if found.
  --enable-gtk-deprecation-warnings
                          Show Gtk+/Gdk deprecation warnings for Gtk+ >= 3.0
  --disable-build-details Make the build more deterministic by omitting host
                          names, time stamps, etc. from the output.
  --disable-largefile     omit support for large files
  --disable-year2038      omit support for timestamps past the year 2038
  --enable-gcc-warnings[=TYPE]
                          control generation of GCC warnings. The TYPE 'yes'
                          means to fail if any warnings are issued;
                          'warn-only' means issue warnings without failing
                          (default for developer builds); 'no' means disable
                          warnings (default for non-developer builds).
  --enable-check-lisp-object-type
                          Enable compile time checks for the Lisp_Object data
                          type, which can catch some bugs during development.
  --enable-link-time-optimization
                          build with link-time optimization (experimental; see
                          INSTALL)
  --disable-silent-rules  verbose build output (undo: "make V=0")
  --enable-cross-guesses={conservative|risky}
                          specify policy for cross-compilation guesses
  --disable-acl           do not support ACLs

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --without-all           omit almost all features and build small executable
                          with minimal dependencies
  --with-mailutils        rely on GNU Mailutils, so that the --without-pop
                          through --with-mailhost options are irrelevant; this
                          is the default if GNU Mailutils is installed
  --with-pop              Support POP mail retrieval if Emacs movemail is used
                          (not recommended, as Emacs movemail POP is
                          insecure). This is the default only on native
                          MS-Windows.
  --with-kerberos         support Kerberos-authenticated POP
  --with-kerberos5        support Kerberos version 5 authenticated POP
  --with-hesiod           support Hesiod to get the POP server host
  --with-mail-unlink      unlink, rather than empty, mail spool after reading
  --with-mailhost=HOSTNAME
                          string giving default POP mail host
  --with-sound=VALUE      compile with sound support (VALUE one of: yes, alsa,
                          oss, bsd-ossaudio, no; default yes). Only for
                          GNU/Linux, FreeBSD, NetBSD, MinGW, Cygwin.
  --with-pdumper=VALUE    enable pdumper support unconditionally ('yes', 'no',
                          or 'auto': default 'auto')
  --with-unexec=VALUE     enable unexec support unconditionally ('yes', 'no',
                          or 'auto': default 'auto')
  --with-dumping=VALUE    kind of dumping to use for initial Emacs build
                          (VALUE one of: pdumper, unexec, none; default
                          pdumper)
  --with-x-toolkit=KIT    use an X toolkit (KIT one of: yes or gtk, gtk2,
                          gtk3, lucid or athena, motif, no)
  --with-wide-int         prefer wide Emacs integers (typically 62-bit); on
                          32-bit hosts, this allows buffer and string size up
                          to 2GB, at the cost of 10% to 30% slowdown of Lisp
                          interpreter and larger memory footprint

  --without-xim           at runtime, default X11 XIM to off
  --without-xdbe          don't use X11 double buffering support
  --with-ns               use Nextstep (macOS Cocoa or GNUstep) windowing
                          system. On by default on macOS.
  --with-w32              use native MS Windows GUI in a Cygwin build
  --with-pgtk             use GTK to support window systems other than X
  --without-gpm           don't use -lgpm for mouse support on a GNU/Linux
                          console
  --without-dbus          don't compile with D-Bus support

  --with-small-ja-dic     generate a smaller-size Japanese dictionary
  --with-file-notification=LIB
                          use a file notification library (LIB one of: yes,
                          inotify, kqueue, gfile, w32, no)
  --with-xwidgets         enable use of xwidgets in Emacs buffers (requires
                          gtk3 or macOS Cocoa)
  --with-be-app           enable use of Haiku's Application Kit as a window

                          user for shared game score files. An argument
                          prefixed by ':' specifies a group instead.
  --with-gnustep-conf=FILENAME
                          name of GNUstep configuration file to use on systems
                          where the command 'gnustep-config' does not work;
                          default $GNUSTEP_CONFIG_FILE, or
                          /etc/GNUstep/GNUstep.conf
  --with-native-compilation[=TYPE]
                          compile with Emacs Lisp native compiler support. The
                          TYPE 'yes' (or empty) means to enable it and compile
                          natively preloaded Lisp files; 'no' means to disable
                          it; 'aot' will make the build process compile all
                          the Lisp files in the tree natively ahead of time.
                          (This will usually be quite slow.)
  --with-x                use the X Window System
  --without-libgmp        do not use the GNU Multiple Precision (GMP) library;
                          this is the default on systems lacking libgmp.
  --without-included-regex
                          don't compile regex; this is the default on systems
                          with recent-enough versions of the GNU C Library
                          (use with caution on other systems).

/* 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)  */
