935 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
937 Usage: $0 [OPTION]... [VAR=VALUE]...
939 To assign environment variables (e.g., CC, CFLAGS...), specify them as
940 VAR=VALUE. See below for descriptions of some of the useful variables.
942 Defaults for the options are specified in brackets.
945 -h, --help display this help and exit
946 --help=short display options specific to this package
947 --help=recursive display the short help of all the included packages
948 -V, --version display version information and exit
949 -q, --quiet, --silent do not print \`checking...' messages
950 --cache-file=FILE cache test results in FILE [disabled]
951 -C, --config-cache alias for \`--cache-file=config.cache'
952 -n, --no-create do not create output files
953 --srcdir=DIR find the sources in DIR [configure dir or \`..']
958 Installation directories:
959 --prefix=PREFIX install architecture-independent files in PREFIX
961 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
964 By default, \`make install' will install all the files in
965 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
966 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
967 for instance \`--prefix=\$HOME'.
969 For better control, use the options below.
971 Fine tuning of the installation directories:
972 --bindir=DIR user executables [EPREFIX/bin]
973 --sbindir=DIR system admin executables [EPREFIX/sbin]
974 --libexecdir=DIR program executables [EPREFIX/libexec]
975 --datadir=DIR read-only architecture-independent data [PREFIX/share]
976 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
977 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
978 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
979 --libdir=DIR object code libraries [EPREFIX/lib]
980 --includedir=DIR C header files [PREFIX/include]
981 --oldincludedir=DIR C header files for non-gcc [/usr/include]
982 --infodir=DIR info documentation [PREFIX/info]
983 --mandir=DIR man documentation [PREFIX/man]
989 --program-prefix=PREFIX prepend PREFIX to installed program names
990 --program-suffix=SUFFIX append SUFFIX to installed program names
991 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
994 --build=BUILD configure for building on BUILD [guessed]
995 --host=HOST cross-compile to build programs to run on HOST [BUILD]
996 --target=TARGET configure for building compilers for TARGET [HOST]
