  <h1>Optional Libraries</h1>

  <p>
    Most external libraries used by XEmacs can be found at the XEmacs
    FTP site: <a href="http://ftp.xemacs.org/pub/xemacs/aux/"
      >http://ftp.xemacs.org/pub/xemacs/aux/</a>.</p>

  <p>
    This page lists programs that are not included in the XEmacs
    distribution, but which are either used by various packages that are
    in the distribution or are enhancements which can be compiled into
    XEmacs.  Where available, ftp sites, web home pages, and configure flags
    (although you should never have to specify library configure flags
    since they are autodetected) are indicated below.</p>

  <p>
    Most of the files listed below contain the sources to these programs,
    and you will have to build them yourself.  However, some binaries are
    available for the Win32 (i.e. native Windows 9x/NT/2000/XP), Cygwin and
    MinGW platforms.</p>

  <h1><a name="section-1.">Windows Binaries:</a></h1>
  <p>
    The <a href="win32">win32</a>
    directory contains binaries for common graphics libraries needed for
    building XEmacs and for zlib, needed to support the PNG library.
    We recommend that you run <a href="win32/optional-libs.exe">
    optional-libs.exe</a>, a self-extracting executable, which will
    install pre-built binaries for all of the optional graphics libraries
    needed by XEmacs, in the correct hierarchy as expected by XEmacs.
    Then just set the <tt>OPTIONAL_LIBRARY_DIR</tt> parameter to the
    appropriate directory in which you installed the libraries (by default,
    <tt>c:\src</tt>).</p>

  <p>
    We no longer provide binaries for CVS, SSH or patch.  If you want these,
    just install <a href="http://www.cygwin.com">Cygwin</a>, which provides
    versions of these and all other common Unix utilities, has an easy
    install program, and is frequently updated.
  </p>

  <h1><a name="section-2.">Cygwin, XFree86 Binaries:</a></h1>
  <p>
    <strong>Cygwin</strong> is a POSIX emulation environment for MS
    Windows.  Development on Cygwin is quite active.  Nearly every major or
    even semi-significant open-source Unix package on earth has been ported
    to Cygwin and is available in pre-built format from the Cygwin website.
    If you are planning on doing any development on XEmacs under Windows
    it's pretty much mandatory to install Cygwin.  Among other things, you
    will undoubtedly need ssh and CVS, and GNU make as well if you want to
    rebuild the XEmacs packages or the web site.</p>

  <p>
    Get Cygwin from <a href="http://www.cygwin.com/">http://www.cygwin.com/
    </a>.  (You will be asked to choose a mirror site; try
    mirrors.rcn.net.) Part of the setup process allows you to install
    XFree86.  Other useful packages to consider are CVS (for access to the
    XEmacs source tree), ssh (needed in conjunction with CVS), make (for
    building the packages or the web site), gcc (for compiling XEmacs under
    Cygwin), png/zlib/Xpm/jpeg/tiff/compface libraries (see below), various
    other libraries (see below; prebuilt versions of most of them exist),
    autoconf (for rebuilding <tt>configure</tt>), TeX (for rebuilding
    certain parts of the package hierarchy), and wget (for rebuilding the
    web site).</p>

  <h1><a name="section-3.">MinGW Binaries:</a></h1>
  <p>
    Get MinGW from <a href="http://www.mingw.org/">http://www.mingw.org/</a>.
    (<strong>MinGW</strong> is a version of GCC that uses
    native Microsoft DLL's instead of requiring a POSIX-emulation DLL,
    as Cygwin does.)</p>

  <p>
    The <a href="http://ftp.xemacs.org/pub/xemacs/aux/mingw">mingw</a>
    directory contains binaries for the graphics libraries (Xpm, png+zlib,
    jpeg, tiff, compface -- remember that gif support is built in) needed
    for building XEmacs using the MinGW compiler.  <strong>NOTE</strong>:
    Many of the binaries are out-of-date.  Compile
    them yourself if possible.</p>

  <h1><a name="section-4.">Image Format Libraries:</a></h1>

  <p>
    The <strong>XPM</strong> image format library
    <strong>(virtually mandatory when building XEmacs)</strong><br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/xpm-3.4k.tar.gz">xpm-3.4k.tar.gz</a><br />

    configure flag: <tt>--with-xpm</tt></p>

  <p>
    The <strong>PNG</strong> image format library
    <strong>(strongly encouraged when building XEmacs)</strong><br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/libpng-1.2.8-config.tar.gz">libpng-1.2.8-config.tar.gz</a><br />

    configure flag: <tt>--with-png</tt></p>

  <p>
    The <strong>ZLIB</strong> compression library <strong>(strongly
    encouraged when building XEmacs)</strong> is used by the PNG library.
    A GZIP coding system is also available, in XEmacs 21.5 and onward.<br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/zlib-1.2.3.tar.gz">zlib-1.2.3.tar.gz</a><br />
    <a href="http://www.zlib.net/">http://www.zlib.net/</a><br />
    configure flag: <tt>--with-zlib</tt></p>

  <p>

    (useful when building XEmacs)<br />
    <a href="http://downloads.sourceforge.net/giflib/giflib-4.1.6.tar.gz">giflib-4.1.6.tar.gz</a><br />
    <a href="http://sourceforge.net/projects/giflib/">http://sourceforge.net/projects/giflib/</a><br />
    configure flag: <tt>--with-gif</tt></p>

  <p>
    The <strong>TIFF</strong> image format library
    (not especially important when building XEmacs)<br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/tiff-3.7.3.tar.gz">tiff-3.7.3.tar.gz</a><br />
    <a href="http://www.remotesensing.org/libtiff/">http://www.remotesensing.org/libtiff/</a><br />
    configure flag: <tt>--with-tiff</tt></p>

  <p>
    <strong>compface</strong> (not especially important when building XEmacs)
    is an old library for viewing X-Faces in messages.
    It is not really being maintained, but still works.
    The version of this library at xemacs.org
    includes the <tt>xbm2xface.pl</tt> script, written by stig@hackvan.com,
    which may be useful when generating your own xface.<br />

  <h1><a name="section-5.">X-Windows Widget Sets:</a></h1>

  <p>
    <strong>GTK+</strong> is a modern widget set for X Windows.
    XEmacs still requires GTK+ v1, although support for GTK+ v2 is planned.

    <a href="http://www.gtk.org/">http://www.gtk.org/</a><br />
    configure flag: <tt>--with-gtk</tt></p>

  <p>
    <strong>Xaw3d</strong> is designed to be a drop-in replacement for the
    Athena widget library that `looks cooler'.<br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/Xaw3d-1.5.tar.gz">Xaw3d-1.5.tar.gz</a><br />

    configure flag: <tt>--with-athena=3d</tt></p>

  <p>
    <strong>OpenMotif</strong> is the free release of Motif, a standard widget
    set for X Windows.<br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/openmotif2.1.30pl5.tar.gz">openmotif2.1.30pl5.tar.gz</a><br />
    <a href="http://www.opengroup.org/openmotif/">http://www.opengroup.org/openmotif/</a><br />
    configure flag: <tt>--with-scrollbars=motif,--with-dialogs=motif,--with-widgets=motif,--with-xim=motif</tt><br />
  (We <strong>don't</strong> currently recommend compiling with Motif menubars,
  as they are probably broken.  They were broken awhile ago and no one has
  tried to fix them.)</p>

  <p>
    <strong>LessTif</strong> is a library that is compatible with Motif, dating back from the days before Motif was free and still actively developed.<br />
    <a href="http://ftp.xemacs.org/pub/xemacs/aux/lesstif-0.94.4.tar.gz">lesstif-0.94.4.tar.gz</a><br />
    <a href="http://www.lesstif.org/">http://www.lesstif.org/</a><br />
    configure flag: <tt>--with-scrollbars=motif,--with-dialogs=motif,--with-widgets=motif</tt><br />
  (Same caveats apply for menubars as with OpenMotif.  Also LessTif didn't use
    to work with XIM; this may have changed.)</p>

  <h1><a name="section-6.">Other Multimedia:</a></h1>
  <p>
