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

811an installation prefix other than \`$ac_default_prefix' using \`--prefix',

853  --with-glu-libdir=<libdir> Specify directories to search for the GLU library.
854                          Expects to find <libdir>/libglu.a
855  --with-glu-incdir=<incdir> Specify directories to search for the GLU headers
856  --with-vis-libdir=<libdir> Specify directories to search for the VIS
857                          and headers.  Defaults to \".\".
858                          Expects to find <libdir>/libvis.a
859  --with-local-srcdir=<srcdir> Specify the root directory to search for
860                          source for packages (the PKGS list).
861                          Expects to find, e.g., <srcdir>/tbl/tbl.c
862  --with-bdd=<bddPackage> Specify the BDD library to link against.
863                          Defaults to --with-bdd=cu.
864  --with-comp-mode=<mode> Specify a special compilation mode:
865                          optimize (the default): Produce optimized
866                                code, with symbol table information
867                                if supported on the platform/compiler,
868                                and without asserts.
869                          debug: Produce unoptimized code with symbol table
870                                information and asserts enabled
871                          purify: Unoptimized code linked with purify
872                          quantify: Optimized code without asserts
873                                linked with quantify
874
875Some influential environment variables:
876  CC          C compiler command
877  CFLAGS      C compiler flags
878  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
879              nonstandard directory <lib dir>
880  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
881              headers in a nonstandard directory <include dir>
882  CPP         C preprocessor
883
884Use these variables to override the choices made by `configure' or to help
885it to find libraries and programs with nonstandard names/locations.
