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.
Many features require external packages to be installed first.
Get them from ftp://ftp.xemacs.org/pub/xemacs/aux.
Use colons (or quoted spaces) to separate directory names in option
values which are PATHs (i.e. lists of directories).
The results of configure tests are saved in config.log, which is useful
for diagnosing problems.
--help Issue this usage message.
--verbose Accepted but ignored.
--extra-verbose Display more information, useful for debugging.
--compiler=PROG C compiler to use
--xemacs-compiler=PROG compiler to use to compile just the xemacs executable.
If you want to compile XEmacs as C++, use e.g.
`--xemacs-compiler=g++'. This turns on a lot of
--with-gcc (*) Use GCC to compile XEmacs.
--cflags=FLAGS Compiler flags (such as -O); setting this overrides
all default compiler flags except those that control
--cflags-warning=FLAGS Override compiler flags used to control warnings.
Normally, don't set this, as XEmacs already turns on
the maximum safe warning level.
--with-optimization Control whether compilation is optimized.
By default, optimization is on in release versions
and off in beta versions, since it can interfere
with proper stack backtraces.
Override compiler flags used to control optimization.
Only has an effect when optimization is enabled.
Normally, don't set this, as XEmacs will already set
the maximum safe optimization flags appropriate for
the compiler being invoked.
Override compiler flags used to add debugging
information to the executable. Normally, debugging
information is added whenever possible (i.e. unless
optimization is turned on and the compiler does not
permit debugging and optimization simultaneously).
--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
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. Allows you to build
XEmacs in various different ways using the same
--prefix=DIR Install files below DIR. Defaults to `/usr/local'.
--with-prefix=no Don't compile the value of --prefix into the
--with-netinstall Compile in support for installation over the internet.
Only functional on the MS Windows platforms.
You may also control individually where various
parts of XEmacs are installed. 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.
Run-time path-searching options:
--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-prefix=PATH Specify a directory under which packages will
be searched. The directories `xemacs-packages' and
(if MULE support exists) `mule-packages' (along with,
optionally, `site-packages') should exist under this
directory. This is preferred to specifying
`--package-path' directly and is equivalent to
(or the same without `.../mule-packages' if no
MULE support exists)
--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
If PATH has two components, the first is
early, the second is late.
--infopath=PATH Directories to search for Info documents, info dir
and localdir files in case run-time searching
for them fails.
--with-gtk Support GTK on the X Window System. (EXPERIMENTAL)
--with-gnome Support GNOME on the X Window System. (EXPERIMENTAL)
--with-x11 (*) Support the X Window System.
--x-includes=DIR Search for X header files in DIR.
--x-libraries=DIR Search for X libraries in DIR.
--with-msw (*) Support MS Windows as a window system (only under
Cygwin and MinGW). `--with-msw=no' may be needed on
*nix systems with Wine installed.
--with-toolbars=no Don't compile with any toolbar support.
--with-wmcommand=no Compile without realized leader window which will
keep the WM_COMMAND property.
--with-athena=TYPE Use TYPE Athena widgets (xaw, 3d, next, 95, or xpm).
--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.
Lucid menubars are the default.
--with-scrollbars=TYPE Use TYPE scrollbars (lucid, motif, athena, or no).
Lucid scrollbars are the default.
--with-dialogs=TYPE Use TYPE dialog boxes (lucid, motif, athena, or no).
There are no true Lucid dialogs; Motif dialogs will be
used if Motif can be found, else Athena is used.
--with-widgets=TYPE Use TYPE native widgets (lucid, motif, athena, or no).
Other widget types are currently unsupported.
There are no true Lucid widgets; Motif widgets will be
used if Motif can be found, else Athena is used.
--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
--with-xmu=no (*) For those unfortunates whose vendors don't ship Xmu.
--external-widget Compile with external widget support.
TTY (character terminal) options:
--with-tty=no Don't support ttys.
--with-ncurses (*) Use the ncurses library for tty support.
--with-gpm (*) Compile in GPM mouse support for ttys.
--with-xpm (*) Compile with support for XPM images. PRACTICALLY
REQUIRED. Although this library is nonstandard and
a real hassle to build, many basic things (e.g.
toolbars) depend on it, and you will run into
many problems without it.
--with-png (*) Compile with support for PNG images. Recommended
because the images on the About page are not viewable
--with-jpeg (*) Compile with support for JPEG images. Useful if
you are using a mail, news reader, or web browser
in XEmacs, so that JPEG images can be displayed.
--with-tiff (*) Compile with support for TIFF images. Possibly
useful, for the same reason as JPEG images.
--with-xface (*) Compile with support for X-Face mail headers.
Requires the compface package. Of doubtful
--with-gif=no Compile without the (builtin) support for GIF images.
--with-sound=TYPE[,TYPE[,...]] (*) Compile with sound support.
Valid types are `native', `nas' and `esd'.
Prefix a type with 'no' to disable.
The first type can be `none' or `all'. `none' means
`nonative,nonas,noesd'. `all' means `native,nas,esd'.
Later options override earlier ones for the same TYPE.
The default is to autodetect all sound support except
for ESD which defaults to off.
--native-sound-lib=LIB Native sound support library. Needed on Suns
with `--with-sound=native,nas' because both sound
libraries are called libaudio.
--with-mule Compile with Mule (MUlti-Lingual Emacs) support,
needed to support non-Latin-1 (including Asian)
--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 commercial package Wnn6.
--with-i18n3 Compile with I18N level 3 (support for message
translation). This doesn't currently work.
--with-xfs Compile with XFontSet support for internationalized
menubar. Incompatible with `--with-xim=motif'.
`--with-menubars=lucid' (the default) is desirable.
Turns on by default auto-detection of end-of-line type
when reading a file. Applies to those platforms where
auto-detection is off by default (non-Mule Unix). Has
no effect otherwise.
Disable use of lock files to detect multiple edits
of the same file.
--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-ldap (*) Compile with support for the LDAP protocol.
--with-postgresql (*) Compile with support for the PostgreSQL RDBMS.
--mail-locking=TYPE (*) Specify the locking to be used by movemail to prevent
concurrent updates of mail spool files. Valid types
are `lockf', `flock', `file', `dot' (same as `file'),
`locking', `mmdf' and `pop' (equivalent to
--with-pop Support POP for mail retrieval.
--with-kerberos Support Kerberos-authenticated POP.
--with-hesiod Support Hesiod to get the POP server host.
--with-tooltalk (*) Support the ToolTalk IPC protocol.
--with-socks Compile with support for SOCKS (an Internet proxy).
--with-dnet (*) Compile with support for DECnet.
--with-ipv6-cname Try IPv6 information first when canonicalizing host
names. This option has no effect unless system
supports getaddrinfo(3) and getnameinfo(3).
Memory allocation options:
--rel-alloc Use the relocating allocator (default for this option
--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.
Emacs Lisp options:
--use-number-lib=TYPE Compile in support for bignums, ratios, or bigfloats
using library support. TYPE must be one of "gmp"
(for GNU MP), "mp" (for BSD MP), or "no" (disabled).
--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.
--quick-build Speed up the build cycle by leaving out steps where
XEmacs will still work (more or less) without them.
Potentially dangerous if you don't know what you're
doing. This (1) doesn't garbage-collect after loading
each file during dumping, (2) doesn't
automatically rebuild the DOC file (remove it by hand
to get it rebuilt), (3) Removes config.h, lisp.h and
associated files from the dependency lists, so changes
to these files don't automatically cause all .c files
to be rebuilt.
--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. WARNING: This has
a tendency to trigger compiler bugs, especially in
combination with other features that increase the
complexity of expressions, for example `--with-mule'
and `--error-checking=all'. Crashes have been
observed with union type in combination with the
two options just mentioned under various versions of
GCC as well as MSVC++ 6.0. Furthermore, many
debuggers have problems (i.e. bugs) dealing with
unions, and even for those that don't, debugging can
be inconvenient because of no syntax for entering a
union. We recommend `--use-union-type' *ONLY* for
testing purposes, not for production builds. If you
are using `-use-union-type' and get some weird
crash, try redoing without union type.
--with-quantify Add support for performance debugging using Quantify.
--with-purify Add support for memory debugging using Purify.
--with-workshop Support the Sun WorkShop (formerly Sparcworks)
--pdump New, portable, relocatable dumper. Currently works
quite well, somewhere in beta-to-late-beta, we
might say. (Infamous for being the former
and-your-wife-leaves-you" portable dumper.)
--dump-in-exec Put the dump image into the executable (enabled by
default for `pdump', not enabled by default in
combination with `mc-alloc'.
--use-kkcc Enable the use of new GC algorithms. (EXPERIMENTAL)
--mc-alloc Enable the new allocator. (EXPERIMENTAL)
--with-modules (*) Compile in experimental support for dynamically
loaded libraries (Dynamic Shared Objects).
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. Configure
flags take precedence over environment variables, if both are specified.
