938 \`configure' configures this package to adapt to many kinds of systems.
940 Usage: $0 [OPTION]... [VAR=VALUE]...
942 To assign environment variables (e.g., CC, CFLAGS...), specify them as
943 VAR=VALUE. See below for descriptions of some of the useful variables.
945 Defaults for the options are specified in brackets.
948 -h, --help display this help and exit
949 --help=short display options specific to this package
950 --help=recursive display the short help of all the included packages
951 -V, --version display version information and exit
952 -q, --quiet, --silent do not print \`checking...' messages
953 --cache-file=FILE cache test results in FILE [disabled]
954 -C, --config-cache alias for \`--cache-file=config.cache'
955 -n, --no-create do not create output files
956 --srcdir=DIR find the sources in DIR [configure dir or \`..']
961 Installation directories:
962 --prefix=PREFIX install architecture-independent files in PREFIX
964 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
967 By default, \`make install' will install all the files in
968 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
969 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
970 for instance \`--prefix=\$HOME'.
972 For better control, use the options below.
974 Fine tuning of the installation directories:
975 --bindir=DIR user executables [EPREFIX/bin]

1108 Some influential environment variables:
1109 CC C compiler command
1110 CFLAGS C compiler flags
1111 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1112 nonstandard directory <lib dir>
1113 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
1114 headers in a nonstandard directory <include dir>
1116 GMPLIBS How to link GMP
1117 GMPINC How to find GMP include files
1119 Use these variables to override the choices made by `configure' or to help
1120 it to find libraries and programs with nonstandard names/locations.
