782Usage: $0 [OPTION]... [VAR=VALUE]...
783
784To assign environment variables (e.g., CC, CFLAGS...), specify them as
785VAR=VALUE.  See below for descriptions of some of the useful variables.
786
787Defaults for the options are specified in brackets.
788
789Configuration:
790  -h, --help              display this help and exit
791      --help=short        display options specific to this package
792      --help=recursive    display the short help of all the included packages
793  -V, --version           display version information and exit
794  -q, --quiet, --silent   do not print \`checking...' messages
795      --cache-file=FILE   cache test results in FILE [disabled]
796  -C, --config-cache      alias for \`--cache-file=config.cache'
797  -n, --no-create         do not create output files
798      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

808
809By default, \`make install' will install all the files in
810\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
811an installation prefix other than \`$ac_default_prefix' using \`--prefix',
812for instance \`--prefix=\$HOME'.

855  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
856  --with-local-srcdir=<srcdir> Specify the root directory to search for
857                          source for packages (the PKGS list).
858                          Expects to find, e.g., <srcdir>/array/array.c
859  --with-datasize=<size>  (Default: 67108864.) Specify maximum datasize in
860                          bytes for systems without working getrlimit.
861                          The application may use this value to size some
862                          data structures, but may still try to exceed it.
863  --with-comp-mode=<mode> Specify a special compilation mode:
864                          optimize (the default): Produce optimized
865                                code, with symbol table information
866                                if supported on the platform/compiler,
867                                and without asserts.
868                          debug: Produce unoptimized code with symbol table
869                                information and asserts enabled
870                          purify: Unoptimized code linked with purify
871                          quantify: Optimized code without asserts
872                                linked with quantify
873
874Some influential environment variables:
875  CC          C compiler command
876  CFLAGS      C compiler flags
877  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
878              nonstandard directory <lib dir>
879  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
880              headers in a nonstandard directory <include dir>
881  CPP         C preprocessor
882
883Use these variables to override the choices made by `configure' or to help
884it to find libraries and programs with nonstandard names/locations.
