1339 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1340
1341 Usage: $0 [OPTION]... [VAR=VALUE]...
1342
1343 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1344 VAR=VALUE.  See below for descriptions of some of the useful variables.
1345
1346 Defaults for the options are specified in brackets.
1347
1348 Configuration:
1349   -h, --help              display this help and exit
1350       --help=short        display options specific to this package
1351       --help=recursive    display the short help of all the included packages
1352   -V, --version           display version information and exit
1353   -q, --quiet, --silent   do not print \`checking ...' messages
1354       --cache-file=FILE   cache test results in FILE [disabled]
1355   -C, --config-cache      alias for \`--cache-file=config.cache'
1356   -n, --no-create         do not create output files
1357       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1358
1359 Installation directories:
1360   --prefix=PREFIX         install architecture-independent files in PREFIX
1361                           [$ac_default_prefix]
1362   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1363                           [PREFIX]
1364
1365 By default, \`make install' will install all the files in
1366 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1367 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1368 for instance \`--prefix=\$HOME'.
1369
1370 For better control, use the options below.

1372 Fine tuning of the installation directories:
1373   --bindir=DIR            user executables [EPREFIX/bin]

1475   LIBS        libraries to pass to the linker, e.g. -l<library>
1476   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

1478   CPP         C preprocessor
1479   CXX         C++ compiler command
1480   CXXFLAGS    C++ compiler flags
