789 \`configure' configures this package to adapt to many kinds of systems.
791 Usage: $0 [OPTION]... [VAR=VALUE]...
793 To assign environment variables (e.g., CC, CFLAGS...), specify them as
794 VAR=VALUE. See below for descriptions of some of the useful variables.
796 Defaults for the options are specified in brackets.
799 -h, --help display this help and exit
800 --help=short display options specific to this package
801 --help=recursive display the short help of all the included packages
802 -V, --version display version information and exit
803 -q, --quiet, --silent do not print \`checking...' messages
804 --cache-file=FILE cache test results in FILE [disabled]
805 -C, --config-cache alias for \`--cache-file=config.cache'
806 -n, --no-create do not create output files
807 --srcdir=DIR find the sources in DIR [configure dir or \`..']
812 Installation directories:
813 --prefix=PREFIX install architecture-independent files in PREFIX
815 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
818 By default, \`make install' will install all the files in
819 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
820 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
821 for instance \`--prefix=\$HOME'.
823 For better control, use the options below.
825 Fine tuning of the installation directories:
826 --bindir=DIR user executables [EPREFIX/bin]
827 --sbindir=DIR system admin executables [EPREFIX/sbin]
828 --libexecdir=DIR program executables [EPREFIX/libexec]

835 --oldincludedir=DIR C header files for non-gcc [/usr/include]
836 --infodir=DIR info documentation [PREFIX/info]
837 --mandir=DIR man documentation [PREFIX/man]
843 --program-prefix=PREFIX prepend PREFIX to installed program names
844 --program-suffix=SUFFIX append SUFFIX to installed program names
845 --program-transform-name=PROGRAM run sed PROGRAM on installed program names

931 Some influential environment variables:
932 CC C compiler command
933 CFLAGS C compiler flags
934 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
935 nonstandard directory <lib dir>
936 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
937 headers in a nonstandard directory <include dir>
939 GMPLIBS How to link GMP
940 GMPINC How to find GMP include files
942 Use these variables to override the choices made by `configure' or to help
943 it to find libraries and programs with nonstandard names/locations.
