'configure' configures GNU M4 1.4.21 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print 'checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for '--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or '..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc. You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/m4]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

Program names:

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--enable-c++ also build C++ sources
--disable-largefile omit support for large files
--enable-threads={isoc|posix|isoc+posix|windows}
specify multithreading API
--disable-threads build without multithread safety
--enable-gcc-warnings turn on lots of GCC warnings (for developers)
--enable-cross-guesses={conservative|risky}
specify policy for cross-compilation guesses
--disable-assert turn off assertions
--disable-rpath do not hardcode runtime library paths
--enable-changeword enable -W and changeword() builtin
--disable-nls do not use Native Language Support
--enable-year2038 support timestamps after 2038
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-libsigsegv use the GNU libsigsegv library, when present,
instead of the gnulib module 'sigsegv'
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-libsigsegv-prefix[=DIR] search for libsigsegv in DIR/include and DIR/lib
--without-libsigsegv-prefix don't search for libsigsegv in includedir and libdir
--with-gnulib-prefix=DIR search for gnulib's runtime data in DIR/share
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--without-included-regex
don't compile regex; this is the default on systems
with recent-enough versions of the GNU C Library
(use with caution on other systems).
--with-packager String identifying the packager of this software
--with-packager-version Packager-specific version information
--with-packager-bug-reports
Packager info for bug reports (URL/e-mail/...)
--with-syscmd-shell shell used by syscmd [/bin/sh]
--with-dmalloc use dmalloc, as in dmalloc.tar.gz from
@/ftp.antaire.com:antaire/src/dmalloc.
--with-libintl-prefix[=DIR] search for libintl in DIR/include and DIR/lib
--without-libintl-prefix don't search for libintl in includedir and libdir
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
CXX C++ compiler command
CXXFLAGS C++ compiler flags
Use these variables to override the choices made by 'configure' or to help
it to find libraries and programs with nonstandard names/locations.
