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.

Options marked with a (*) are autodetected.

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=XXXX		Specify compiler.  Overrides environment variable CC.
--with-gcc (*)		Use GCC to compile XEmacs.
--with-gcc=no		Don't use GCC to compile XEmacs.
--with-gnu-make		Write the Makefiles to take advantage of
			special features of GNU Make. (GNU Make
			works fine on the Makefiles even without this
			option.  This just allows for simultaneous
			in-place and --srcdir building.)
--cflags=FLAGS		Compiler flags. Overrides environment variable CFLAGS.
--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
			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.
			See also --with-gnu-make.
--const-is-losing=no	Allow the use of const in the source code.
--with-gung		Build with new-style Lisp_Objects.

Installation options:

--prefix=DIR		Install files below DIR.  Defaults to `/usr/local'.

--with-x11 (*)		Support the X Window System.
--with-x11=no		Don't support X.
--x-includes=DIR 	Search for X header files in DIR.
--x-libraries=DIR	Search for X libraries in DIR.
--with-toolbars=no	Don't compile with any toolbar support.
--with-session=no	Compile without realized leader window which will
			keep the WM_COMMAND property. Required for proper
--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-cde (*)		Compile in support for CDE drag and drop.
--with-offix (*)	Compile in support for OffiX drag and drop.
--with-xmu=no (*)	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.
--with-gif (*)		Compile with support for GIF image conversion.
			Requires GifLib 3.1 or greater.  Get it from
			the XEmacs FTP site.
--with-jpeg (*)		Compile with support for JPEG image conversion.
			Requires libjpeg from the Independent JPEG Group.

--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:

--with-tty=no		Don't support TTY-s.
--with-ncurses (*)	Use the ncurses library for tty support.
--with-gpm (*) 		Compile in support for General Purpose Mouse.

--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-kerberos		support Kerberos-authenticated POP
--with-hesiod		support Hesiod to get the POP server host
--with-dnet (*)		Compile with support for DECnet.

                        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-site-lisp        Allow for a site-lisp directory in the XEmacs hierarchy 
			searched before the installation packages.
--package-path=PATH     Directories to search for packages to dump with xemacs.
                        Defaults to
	                Components before the double colon (::) will not
                        be seen at dump time.  They will also show up
                        as the first thing in the various paths.
--infodir=DIR		Directory to install the XEmacs Info manuals and dir in.
    Defaults to: `'.
--infopath=PATH		Directories to search for Info documents, info dir
			and localdir files in case run-time searching

    Defaults to the value of:

Internationalization options:

--with-mule		Compile with Mule (MUlti-Lingual Emacs) support,
			needed to suport 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.)
			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.

Other options:

--puresize=VALUE	Override default amount of space for pure Lisp code.
--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-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
    Defaults to `${statedir}/xemacs/lock'.
--with-system-malloc	Force use of the system malloc, rather than GNU malloc.
--with-debug-malloc	Use the debugging malloc package.

You may also specify any of the `path' variables found in Makefile.in,
including --bindir, --libdir, --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 build process also uses the following environment variables:

CC        C compiler to use (but configure flags take precedence)
CPP       C preprocessor to use (such as /usr/ccs/lib/cpp or cc -E)
CFLAGS    C compiler compilation flags (such as -O)
CPPFLAGS  Compilation flags (such as -I/foo) used only by the preprocessor
LDFLAGS   Additional linker flags (such as -L/foo)
LIBS      Additional libraries (such as -lfoo)

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.
