\`configure' configures this package 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]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --x-includes=DIR        X include files are in DIR
  --x-libraries=DIR       X library files are in DIR
  --datarootdir=DIR      read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR          read-only architecture-independent data [DATAROOTDIR]
  --localedir=DIR        locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR           man documentation [DATAROOTDIR/man]
  --docdir=DIR           documentation root [DATAROOTDIR/doc/PACKAGE]
  --htmldir=DIR          html documentation [DOCDIR]
  --dvidir=DIR           dvi documentation [DOCDIR]
  --pdfdir=DIR           pdf documentation [DOCDIR]
  --psdir=DIR            ps documentation [DOCDIR]

X features:
  --x-includes=DIR    X include files are in DIR
  --x-libraries=DIR   X library files are in DIR

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]

Screen locking options:
  --enable-locking        Compile in support for locking the display.
  --disable-locking       Do not allow locking at all.

  --enable-root-passwd	      Allow root passwd to unlock screen.
  --disable-root-passwd       Do not allow that.

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)


Installation options:
  --with-hackdir=DIR      Where to install the hundreds of demo executables.
                          Default: `PREFIX/libexec/xscreensaver/'
  --with-configdir=DIR    Where to install the data files that describe each
                          of the display modes to the GUI.
                          Default: `PREFIX/share/xscreensaver/config/'
  --with-x-app-defaults=DIR
			   Where to install xscreensaver configuration file.

Except where noted, all of the --with options below can also take a
directory argument: for example, `--with-motif=/opt/Motif'.  That would
cause /opt/Motif/include/ to be added to the -I list, and /opt/Motif/lib/
to be added to the -L list, assuming those directories exist.

By default, support for each of these options will be built in, if the
relevant library routines exist.  At run time, they will then be used
only if the X server being used supports them.  Each --with option has
a corresponding --without option, to override building support for them
at all.

Screen blanking and idle-detection options:

  --with-sgi-ext          Include support for the SGI SCREEN_SAVER extension.
  --with-xidle-ext        Include support for the XIDLE extension.
  --with-sgivc-ext        Include support for the SGI-VIDEO-CONTROL extension.
  --with-dpms-ext         Include support for the DPMS extension.
  --with-xinerama-ext     Include support for the XINERAMA extension.
  --with-xf86vmode-ext    Include support for XFree86 virtual screens.
  --with-xf86gamma-ext    Include support for XFree86 gamma fading.
  --with-randr-ext        Include support for the X Resize+Rotate extension.
  --with-proc-interrupts  Include support for consulting the /proc/interrupts
                          file to notice keyboard activity.
  --with-pam              Include support for PAM (Pluggable Auth Modules.)
  --with-pam-service-name=NAME
                          NAME is the name of the PAM service that
                          xscreensaver will authenticate as.
  --with-kerberos         Include support for Kerberos authentication.
  --with-shadow           Include support for shadow password authentication.
  --with-passwd-helper    Include support for an external password
                          verification helper program.
  --with-login-manager    Put a "New Login" button on the unlock dialog that
                          runs a login manager such as gdmflexiserver.

User interface options:

  --with-gtk              Use the Gtk toolkit for the user interface.
  --with-motif            Use the Motif toolkit for the user interface
                          (not recommended.)

Graphics options:

  --with-gl               Build those demos which depend on OpenGL.
  --with-gle              Build those demos which depend on GLE
                          (the OpenGL "extrusion" library.)
  --with-pixbuf           Include support for the GDK-Pixbuf library in some
                          demos, which will make it possible for them to read
                          GIF, JPEG, and PNG files as well.
  --with-xpm              Include support for XPM files in some demos.
                          (Not needed if Pixbuf is used.)
  --with-jpeg             Include support for the JPEG library.
  --with-xshm-ext         Include support for the Shared Memory extension.
  --with-xdbe-ext         Include support for the DOUBLE-BUFFER extension.
  --with-readdisplay      Include support for the XReadDisplay extension.
  --with-image-directory=DIR  By default, some demos may display random images
                          from this directory.
  --with-text-file=FILE   By default, some demos may display this file.
  --with-browser=BROWSER   Specify the browser to show help URL.
  --with-setuid-hacks     Allow some demos to be installed `setuid root'
                          (which is needed in order to ping other hosts.)


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    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  XMKMF       Path to xmkmf, Makefile generator for X Window System

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

# Like AC_TRY_COMPILE, but it uses the already-computed -I directories.

# Like AC_CHECK_LIB, but it uses the already-computed -I and -L directories.
# Use this sparingly; it probably doesn't work very well on X programs.
#


# Like AC_TRY_RUN, but it uses the already-computed -I directories.
# (But not the -L directories!)
#




# Usage: HANDLE_X_PATH_ARG([variable_name],
#                          [--command-line-option],
#                          [descriptive string])
#
# All of the --with options take three forms:
#
#   --with-foo (or --with-foo=yes)
#   --without-foo (or --with-foo=no)
#   --with-foo=/DIR
#
# This function, HANDLE_X_PATH_ARG, deals with the /DIR case.  When it sees
# a directory (string beginning with a slash) it checks to see whether
# /DIR/include and /DIR/lib exist, and adds them to $X_CFLAGS and $X_LIBS

      # The following arcana was gleaned from conversations with
      # Eric Schwartz <erics@col.hp.com>:
      #
      # On HPUX 10.x, the parts of X that HP considers "standard" live in
      # /usr/{include,lib}/X11R6/.  The parts that HP doesn't consider
      # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
      # Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
      # Also, there are symlinks from /usr/include/ and /usr/lib/ into
      # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
      # you don't need any -I or -L arguments.
      #
      # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
      # are the same division as 10.x.  However, there are no symlinks to
      # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
      # arguments are always necessary.
      #
      # However, X11R6 was available on HPUX 9.x as a patch: if that
      # patch was installed, then all of X11R6 went in to
      # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
      #
      # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
      # whether R5 was available as a patch; R6 undoubtedly was not.)
      #
      # So.  We try and use the highest numbered pair of
      # /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
      # that are available.  We do not mix and match different versions
      # of X.
      #
      # Question I still don't know the answer to: (do you?)
      #
      #   * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
      #     /usr/contrib/X11R6/ could be installed as a patch, what was in
      #     that contrib directory?  Did it contain so-called "standard"
      #     X11R6, or did it include Xaw and Xmu as well?  If the former,
      #     where did one find Xaw and Xmu on 9.x R6 systems?  Would this
      #     be a situation where one had to reach into the R5 headers and
      #     libs to find Xmu?  That is, must both R6 and R5 directories
      #     be on the -I and -L lists in that case?

/* 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)  */

#       Checking whether Motif requires -lXpm.
#
#       If this is Motif 2.x, and we have XPM, then link against XPM as well.
#       The deal is, Motif 2.x requires XPM -- but it's a compilation option
#       of the library whether to build the XPM code into libXm, or whether
#       to rely on an external libXm.  So the only way to tell whether XPM is
#       a link-time requirement is to examine libXm.a, which is very
#       difficult to do in an autoconf script.  So... if it's Motif 2.x, we
#       always link against XPM if the XPM lib exists (and this will be a
#       no-op if libXm happens to already have the XPM code in it.)
