XEmacs / configure.usage

Usage: configure [--OPTION[=VALUE] ...] [CONFIGURATION]

Set compilation and installation parameters for XEmacs, and report.

Note that for most of the following options, you can explicitly enable
them using `--OPTION=yes' and explicitly disable them using `--OPTION=no'.
This is especially useful for auto-detected options.
The option `--without-FEATURE' is a synonym for `--with-FEATURE=no'.

Options marked with a (*) are auto-detected.

Use colons (or quoted spaces) to separate directory names in option
values which are PATHs (i.e. lists of directories).

General options:

--help                  Issue this usage message.
--verbose               Display the results of configure tests.
--extra-verbose         Display even more information, useful for debugging.


Compilation options:

--compiler=prog         C compiler to use.
--with-gcc (*)          Use GCC to compile XEmacs.
--without-gcc           Don't use GCC to compile XEmacs.
--cflags=FLAGS          Compiler flags (such as -O)
--cpp=prog              C preprocessor to use (e.g. /usr/ccs/lib/cpp or cc -E)
--cppflags=FLAGS        C preprocessor flags (e.g. -I/foo or -Dfoo=bar)
--libs=LIBS             Additional libraries (e.g. -lfoo)
--ldflags=FLAGS         Additional linker flags (e.g. -L/foo)
--site-includes=PATH    List of directories to search first for header files.
--site-libraries=PATH   List of directories to search first for libraries.
--site-prefixes=PATH    List of directories to search for include/ and lib/
                        subdirectories, just after 'site-includes' and
                        'site-libraries'.
--site-runtime-libraries=PATH
                        List of ALL directories to search for dynamically
                        linked libraries at run time.
--dynamic=yes           Link dynamically if supported by system.
--dynamic=no            Force static linking on systems where dynamic
                        linking is the default.
--srcdir=DIR            Look for the XEmacs source files in DIR.
                        Works best when using GNU Make.


Installation options:

--prefix=DIR            Install files below DIR.  Defaults to `/usr/local'.
--with-prefix		Compile the value of --prefix into the executable.
                        Defaults to `yes'.
--without-prefix        Don't compile the value of --prefix into the executable.


Window-system options:

--with-x11 (*)          Support the X Window System.
--without-x11           Don't support X.

--x-libraries=DIR       Search for X libraries in DIR.
--without-toolbars      Don't compile with any toolbar support.
--without-wmcommand     Compile without realized leader window which will
                        keep the WM_COMMAND property.
--with-menubars=TYPE    Use TYPE menubars (lucid, motif, or no).  The Lucid
                        widgets emulate Motif (mostly) but are faster.
                        *WARNING*  The Motif menubar is currently broken.
--with-scrollbars=TYPE  Use TYPE scrollbars
                        (lucid, motif, athena, athena3d, or no).
--with-dialogs=TYPE     Use TYPE dialog boxes (motif, athena, athena3d, or no).
                        Lucid menubars and scrollbars are the default.
                        Motif dialog boxes will be used if Motif can be found.
--with-widgets=TYPE     Use TYPE widgets (motif, athena, athena3d, or no).
                        Motif widgets will be used if Motif can be found.
                        Other widget types are currently unsupported.
--with-dragndrop (*)    Compile in the generic drag and drop API. This is
                        automatically added if one of the drag and drop
                        protocols is found (currently CDE, OffiX, MSWindows).
                        *WARNING*  The Drag'n'drop support is under development
                                   and is considered experimental.
--with-cde (*)          Compile in support for CDE drag and drop.
--with-offix (*)        Compile in support for OffiX drag and drop.
                        *WARNING*  If you compile in OffiX, you may not be
                                   able to use multiple X displays success-
                                   fully.  If the two servers are from
                                   different vendors, the results may be
                                   unpredictable.
--without-xmu (*)       For those unfortunates whose vendors don't ship Xmu.
--external-widget       Compile with external widget support.
--with-xpm (*)          Compile with support for XPM files.
                        It is highly recommended that you obtain XPM
                        (version 3.4h or better) if you don't already
                        have it.  Get it from the XEmacs FTP site.
--with-xface (*)        Compile with support for X-Face mail header
                        conversion.  Requires the compface library.
                        Get it from the XEmacs FTP site.
--without-gif           Compile without the built-in support for GIF image
                        conversion.
--with-jpeg (*)         Compile with support for JPEG image conversion.
                        Requires libjpeg from the Independent JPEG Group.
                        Get it from the XEmacs FTP site.
--with-png (*)          Compile with support for PNG image conversion.
                        Requires libpng.  Get it from the XEmacs FTP site.
--with-tiff (*)         Compile with support for TIFF image conversion.
                        Requires Sam Lefflier's libtiff library.
                        Get if from the XEmacs FTP site.


TTY options:

--without-tty           Don't support TTY-s.
--with-ncurses (*)      Use the ncurses library for tty support.
--with-gpm (*)          Compile in support for General Purpose Mouse.


Additional features:

--with-tooltalk (*)     Support the ToolTalk IPC protocol.
--with-workshop         Support the Sun WorkShop (formerly Sparcworks)
                        development environment.
--with-socks            Compile with support for SOCKS (an Internet proxy).
--with-database=TYPE (*) Compile with database support.  Valid types are
                        `no' or a comma-separated list of one or more
                        of `berkdb' and either `dbm' or `gnudbm'.
--with-sound=native (*) Compile with native sound support.
--with-sound=nas        Compile with network sound support.
--with-sound=both       Compile with native and network sound support.
--native-sound-lib=LIB  Native sound support library.  Needed on Suns
                        with --with-sound=both because both sound libraries
                        are called libaudio.
--with-pop              support POP for mail retrieval
--with-kerberos         support Kerberos-authenticated POP
--with-hesiod           support Hesiod to get the POP server host
--with-dnet (*)         Compile with support for DECnet.
--with-ldap (*)         Compile with support for the LDAP protocol (requires
                        installed LDAP libraries on the system).
--mail-locking=TYPE (*) Specify the locking to be used by movemail to prevent
                        concurrent updates of mail spool files. Valid types
                        are `lockf', `flock', and `file'.
--with-modules		Compile in experimental support for dynamically
			loaded libraries (Dynamic Shared Objects).
--with-site-lisp=yes    Allow for a site-lisp directory in the XEmacs hierarchy
                        searched before the installation packages.
--with-site-modules=no  Disable site-modules directory in the XEmacs hierarchy,
                        which is searched before the installation modules.
--package-path=PATH     Directories to search for packages to dump with xemacs.
                        PATH splits into three parts separated by double
                        colons (::), an early, a late, and a last part,
                        corresponding to their position in the various
                        system paths:  The early part is always first,
                        the late part somewhere in the middle, and the
                        last part at the very back.
                        Only the late part gets seen at dump time.
                        If PATH has only one component, that component
                        is late.
                        If PATH has two components, the first is
                        early, the second is late.
--infodir=DIR           Directory to install XEmacs Info manuals and dir in.
--infopath=PATH         Directories to search for Info documents, info dir
                        and localdir files in case run-time searching
                        for them fails.
--moduledir=DIR         Directory to install dynamic modules in.

Internationalization options:

--with-mule             Compile with Mule (MUlti-Lingual Emacs) support,
                        needed to support non-Latin-1 (including Asian)
                        languages.
--with-xim=xlib         Compile with support for X input methods,
--with-xim=motif (*)    Used in conjunction with Mule support.
                        Use either raw Xlib to provide XIM support, or
                        the Motif XmIm* routines (when available).
                        NOTE:  On some systems bugs in X11's XIM support
                        will cause XEmacs to crash, so by default,
                        no XIM support is compiled in, unless running
                        on Solaris and the XmIm* routines are detected.
--with-canna (*)        Compile with support for Canna (a Japanese input method
                        used in conjunction with Mule support).
--with-wnn (*)          Compile with support for WNN (a multi-language input
                        method used in conjunction with Mule support).
--with-wnn6 (*)         Compile with support for the comercial package WNN
                        version 6
--with-i18n3            Compile with I18N level 3 (support for message
                        translation).  This doesn't currently work.
--with-xfs              Compile with XFontSet support for bilingual menubar.
                        Can't use this option with --with-xim=motif or xlib.
                        And should have --with-menubars=lucid.


Debugging options:

--debug                 Compile with support for debugging XEmacs.
                        (Causes code-size increase and little loss of speed.)
--error-checking=TYPE[,TYPE]...
                        Compile with internal error-checking added.
                        Causes noticeable loss of speed.  Valid types
                        are extents, bufpos, malloc, gc, typecheck.
--error-checking=none   Disable all internal error-checking (the default).
--error-checking=all    Enable all internal error-checking.
--memory-usage-stats    Compile with additional code to allow you to
                        determine what XEmacs's memory is being used
                        for.  Causes a small code increase but no loss
                        of speed.  Normally enabled when --debug is given.
--no-doc-file           Don't rebuild the DOC file unless it's explicitly
                        deleted.  Only use during development. (It speeds
                        up the compile-run-test cycle.)
--use-union-type        Enable or disable use of a union, instead of an
                        int, for the fundamental Lisp_Object type; this
                        provides stricter type-checking.  Only works with
                        some systems and compilers.
--with-quantify         Add support for performance debugging using Quantify.
--with-purify           Add support for memory debugging using Purify.


Other options:

--rel-alloc             Use the relocating allocator (default for this option
                        is system-dependent).
--with-dlmalloc         Control usage of Doug Lea malloc on systems that have
                        it in the standard C library (default is to use it if
                        it is available).
--with-system-malloc    Force use of the system malloc, rather than GNU malloc.
--with-debug-malloc     Use the debugging malloc package.
--with-clash-detection  Use lock files to detect multiple edits of the same
                        file.  The default is to not do clash detection.
--lockdir=DIR           The directory to put clash detection files in, such as
                        `/var/lock/emacs'.
                        Defaults to `${statedir}/xemacs/lock'.

You may also specify any of the `path' variables found in Makefile.in,
including --bindir, --libdir, --docdir, --lispdir, --sitelispdir,
--datadir, --infodir, --mandir and so on.  Note that we recommend
against explicitly setting any of these variables.  See the INSTALL
file for a complete list plus the reasons we advise not changing them.

If successful, configure leaves its status in config.status.  If
unsuccessful after disturbing the status quo, it removes config.status.

The configure script also recognizes some environment variables, each
of which is equivalent to a corresponding configure flag.  A specified
configure flag always overrides the environment variable.

envvar      configure flag
-----       --------------
CC          --compiler
CPP         --cpp
CFLAGS      --cflags
CPPFLAGS    --cppflags
LDFLAGS     --ldflags
LIBS        --libs
LD_RUN_PATH --site-runtime-libraries

For more details on the install process, consult the INSTALL file.
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
