1265
1266Usage: $0 [OPTION]... [VAR=VALUE]...
1267
1268To assign environment variables (e.g., CC, CFLAGS...), specify them as
1269VAR=VALUE.  See below for descriptions of some of the useful variables.
1270
1271Defaults for the options are specified in brackets.
1272
1273Configuration:
1274  -h, --help              display this help and exit
1275      --help=short        display options specific to this package
1276      --help=recursive    display the short help of all the included packages
1277  -V, --version           display version information and exit
1278  -q, --quiet, --silent   do not print \`checking ...' messages
1279      --cache-file=FILE   cache test results in FILE [disabled]
1280  -C, --config-cache      alias for \`--cache-file=config.cache'
1281  -n, --no-create         do not create output files
1282      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

1287  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1288                          [PREFIX]
1289
1290By default, \`make install' will install all the files in
1291\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1292an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1293for instance \`--prefix=\$HOME'.

1348  LIBS        libraries to pass to the linker, e.g. -l<library>
1349  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

1351  CPP         C preprocessor
1352  CXX         C++ compiler command
1353  CXXFLAGS    C++ compiler flags
1354  CXXCPP      C++ preprocessor

1356Use these variables to override the choices made by `configure' or to help
