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

1084 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a

1088 CXX C++ compiler command
1089 CXXFLAGS C++ compiler flags
1091 CXXCPP C++ preprocessor
