xemacs-21.4 / configure.usage

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

Set compilation and installation parameters for XEmacs, and report.

CONFIGURATION is an optional architecture-vendor-os triple, such as
`sparc-sun-solaris2.7'.  When possible, omit it; configure will detect it.

Conventions for options:
- Boolean options may be explicitly enabled by using `--OPTION=yes' and
  explicitly disabled by using `--OPTION=no'.  `--OPTION' (with no argument)
  is equivalent to `--OPTION=yes'.  `--without-FEATURE' is a synonym for
  `--with-FEATURE=no'.  Denoted `(Bool)' below.
- Enumerated options accept one type from a specified list.  These usually
  accept `--OPTION=no' to disable it entirely, and `--OPTION=yes' often has a
  useful default.  Denoted `(Enum)'.
- Set options accept one or more types from a list of implementations of the
  feature.  All specified implementations will be included.  Prefix a type
  with `no' to disable only that implementation (e.g., `--with-sound=nonas'
  to disable NAS).  The special values `none' and `all' must be first in the
  list if used.  They change the defaults for all types individually from
  autodetect to `no' or `yes' respectively.  `--with-sound=none,native' and
  `--with-sound=noesd,nonas,native' have the same effect.  Denoted `(Set)'.
- Other options have special, option-specific formats.

Options marked with a (*) are auto-detected.  If auto-detected and not
explicitly specified, normally
- Boolean options default to `yes'.
- Enumerated options default to the first detected type in an option-specific
  priority.  Possible defaults are marked with (*) and listed in order.
- Set options default to all detected types.

Some options are provided mainly to disable features which are on by default.
These are indicated by specifying `--OPTION=no'.  Explicitly specifying an
autodetected option which defaults to `yes' makes a failure to detect signal
a fatal configure error.

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

Many features require external packages to be installed.  configure will fail
if an explicitly requested feature depends on an uninstalled package.  On many
Linux systems, you must install -devel versions of the package.

The results of configure tests are saved in config.log, which is useful
for diagnosing problems.  Caching of configure results is disabled.
If successful, configure leaves its status in config.status.  If
unsuccessful after disturbing the status quo, it removes config.status.


General options:

--help                  Issue this usage message.
--verbose               Accepted but ignored.
--extra-verbose         Display more information, useful for debugging.


Compilation options:

--compiler=PROG         C compiler to use
--with-gcc (*)          (Bool) Use GCC to compile XEmacs.
--cflags=FLAGS          Compiler flags (such as `-O')
--cpp=PROG              Set C preprocessor (e.g. `/usr/ccs/lib/cpp', `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 (*)           (Bool) Link dynamically if supported by system.
                        The default is system-dependent.
--srcdir=DIR            Use the XEmacs source files in DIR.  Requires a Make
                        with VPATH; GNU Make is recommended.


Installation options:

--prefix=DIR            Install files below DIR.  Defaults to `/usr/local'.
--with-prefix=no        (Bool) Compile the value of `--prefix' into XEmacs.
--infodir=DIR           Install XEmacs Info manuals and dir in DIR.
--moduledir=DIR         Install dynamic modules in DIR.

You may also specify any of the `path' variables found in Makefile.in.in,
including `--bindir', `--libdir', `--docdir', `--lispdir', `--sitelispdir',
`--datadir', `--mandir' and so on.  These options are DEPRECATED; see INSTALL.


Runtime search path options:

--with-site-modules=no  (Bool) Search directories in the XEmacs hierarchy named
                        `site-modules' before the installed module directories.
--with-site-lisp        (Bool) Search a site-lisp directory in the XEmacs
                        hierarchy before the packaged Lisp.  DEPRECATED.
--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, it is `late'.  With two
                        components, the first is `early', the second is `late'.
--infopath=PATH         Directories to search for Info documents, info dir
                        and localdir files if run-time searching fails.


Window-system options:

--with-gtk              (Bool) Use GTK on the X Window System. (EXPERIMENTAL)
--with-gnome            (Bool) Use GNOME on the X Window System. (EXPERIMENTAL)
--with-x11 (*)          (Bool) 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 (*)          (Bool) 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-wmcommand=no     (Bool) Compile without realized leader window which
                        will keep the WM_COMMAND property.
--with-xmu=no (*)       (Bool) For systems whose vendors don't ship Xmu.


GUI component options:

Select the widget set used to implement components, Lucid, Motif, or Athena.
If `--with-gtk', `--with-gnome', or `--with-msw' are used or implied, treat
component options as Bool.  The `lucid' widgets are a homebrew set, emulating
Motif but faster.  Lucid toolbars, menubars, and scrollbars are implemented
in Xt.  Lucid dialogs and misc widgets wrap and enhance Motif (or Athena if
Motif is not found).  Several enhanced (eg, 3d) Athena libraries may be used,
but the default is the X11R6 `libXaw' (flat) widgets.  Use `--with-athena' to
explicitly specify which library to link against.

--with-toolbars=no      (Bool) Don't compile with any toolbar support.
--with-menubars=TYPE    (Enum) Types: `lucid'(*), `motif', or `no'.
                        *WARNING*  The Motif menubar is currently broken.
--with-scrollbars=TYPE  (Enum) Types: `lucid'(*), `motif', `athena', or `no'.
--with-dialogs=TYPE     (Enum) Types: `lucid'(*), `motif', `athena', or `no'.
--with-widgets=TYPE     (Enum) Types: `lucid', `motif', `athena', or `no'(*).
--with-athena=TYPE      (Enum) Link with the TYPE Athena library.  Types:
                        `xaw' [flat], `3d', `next', `95', or `xpm'.
--with-dragndrop (*)    Support generic drag and drop API. (EXPERIMENTAL)
--with-cde              Support CDE drag and drop API (requires dragndrop).
--with-offix            Support OffiX drag and drop API (requires dragndrop).
                        *WARNING*  OffiX support may interfere with use of
                        multiple X displays.  If the two servers are from
                        different vendors, the results may be unpredictable.


TTY (character terminal) options:

--with-tty=no           Don't support ttys.
--with-ncurses (*)      Use the ncurses library for tty support.
--with-gpm (*)          Support the GPM mouse library for ttys.


Image options:

--with-xpm (*)          Support XPM images.  Toolbars depend on it.
--with-png (*)          Support PNG images.  Strongly recommended.
--with-jpeg (*)         Support JPEG images.
--with-tiff (*)         Support TIFF images.
--with-xface (*)        Support X-Face mail headers.  Requires libcompface.
--with-gif=no           Omit the (builtin) support for GIF images.


Sound options:

--with-sound=TYPES (*)  (Set) Compile with sound support.
                        Types: `native', `nas' and `esd'.
                        Defaults to `noesd', the others are autodetected.
--native-sound-lib=LIB  Native sound support library.  Needed on Suns
                        with `--with-sound=native,nas' because both sound
                        libraries are called libaudio.


Database options:

--with-database=TYPES (*)  (Set) Support key:value databases.
                        Types: `berkdb', `dbm', or `gnudbm'.  `dbm' and
                        `gnudbm' are incompatible with each other.
--with-ldap (*)         (Bool) Support the LDAP protocol.
--with-postgresql (*)   (Bool) Support the PostgreSQL RDBMS.


Mail options:

--mail-locking=TYPE (*) (Enum) Specify the locking method used by movemail.

--with-kerberos         (Bool) Support Kerberos-authenticated POP.
--with-hesiod           (Bool) Support Hesiod to get the POP server host.


Internationalization options:

--with-mule             (Bool) Support non-Latin-1 (including Asian) languages.
--with-xim=TYPE         (Enum) Support X Input Method protocol.  Types:
                        `motif'(*), `xlib', `no'.  Requires Mule.
--with-canna (*)        (Bool) Support the Canna input method.  Requires Mule.
--with-wnn (*)          (Bool) Support the Wnn input methods.  Requires Mule.
--with-wnn6 (*)         (Bool) Support the commercial version of Wnn.
--with-xfs              (Bool) Support internationalized menubar via XFontSets.
                        `--with-menubars=lucid' (the default) is desirable.
                        Incompatible with `--with-xim=motif'.


Additional features:

--with-workshop         (Bool) Support the Sun WorkShop (formerly Sparcworks)
                        development environment.
--with-tooltalk (*)     (Bool) Support the ToolTalk IPC protocol.

--with-dnet (*)         (Bool) Support DECnet.
--with-netinstall       (Bool) Support installation over the internet.
                        Only functional on MS Windows platforms.
--with-ipv6-cname       (Bool) IPv6-ly correct host name canonicalization.
                        IPv6 is always supported if detected; this option
                        prevents blocking and unwanted dialup for CNAME lookup.
--external-widget       (Bool) Export XEmacs as a text widget. (EXPERIMENTAL)
--with-modules (*)      (Bool) Support for dynamically loaded libraries
                        (Dynamic Shared Objects). (EXPERIMENTAL)
--pdump                 (Bool) Somewhat experimental portable dumper.
--with-file-coding      (Bool) Support detection and translation of newline
                        conventions.  Default:  `yes' on Windows, `no' on Unix.
--with-clash-detection=no  (Bool) Detect other instances editing the same file.


Memory allocation options:

--rel-alloc             (Bool) Use the relocating allocator (default for this
                        option is system-dependent).
--with-dlmalloc=no      (Bool) Don't use Doug Lea malloc on systems that have
                        it in the standard C library.
--with-system-malloc    (Bool) Use the system malloc, instead of GNU malloc.
--with-debug-malloc     (Bool) Use the debugging malloc package.
--use-regex-malloc=no   (Bool) Use malloc (not alloca) for regex fail stack.
                        Setting this to 'no' allows crashes - it may be
                        impossible to detect stack exhaustion, and your
                        XEmacs will crash.


Debugging options:

--debug                 (Bool) Compile with support for debugging XEmacs.
                        (Causes code-size increase and little loss of speed.)
--memory-usage-stats    (Bool) 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.
--error-checking=TYPES  (Set) Compile with internal error-checking added.
                        Causes noticeable loss of speed.  Types: `bufpos',
                        `byte-code', `extents', `gc', `glyphs', `malloc', and
                        `typecheck'.  The default value is `none'.
--use-union-type        (Bool) Define Lisp_Object as a union, not an int.
                        Use for strict _static_ type-checking.  Implicated in
                        system-dependent, hard-to-debug crashes.  See PROBLEMS.
                        Do NOT use in production builds.
--no-doc-file           (Bool) Don't rebuild the DOC file unless it's missing.
                        Only use during development.
--quick-build           (Bool) Don't GC when dumping.  Implies `--no-doc-file'.
--with-quantify         (Bool) Support performance debugging using Quantify.
--with-purify           (Bool) Support memory debugging using Purify.


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.
