1313 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1314
1315 Usage: $0 [OPTION]... [VAR=VALUE]...
1316
1317 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1318 VAR=VALUE.  See below for descriptions of some of the useful variables.
1319
1320 Defaults for the options are specified in brackets.
1321
1322 Configuration:
1323   -h, --help              display this help and exit
1324       --help=short        display options specific to this package
1325       --help=recursive    display the short help of all the included packages
1326   -V, --version           display version information and exit
1327   -q, --quiet, --silent   do not print \`checking ...' messages
1328       --cache-file=FILE   cache test results in FILE [disabled]
1329   -C, --config-cache      alias for \`--cache-file=config.cache'
1330   -n, --no-create         do not create output files
1331       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1332
1333 Installation directories:
1334   --prefix=PREFIX         install architecture-independent files in PREFIX
1335                           [$ac_default_prefix]
1336   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1337                           [PREFIX]
1338
1339 By default, \`make install' will install all the files in
1340 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1341 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1342 for instance \`--prefix=\$HOME'.
1343
1344 For better control, use the options below.

1347   --bindir=DIR            user executables [EPREFIX/bin]

1433   CFLAGS      C compiler flags
1434   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1435               nonstandard directory <lib dir>
1436   LIBS        libraries to pass to the linker, e.g. -l<library>
1437   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1438               you have headers in a nonstandard directory <include dir>
1439   CPP         C preprocessor
1440   CXX         C++ compiler command
1441   CXXFLAGS    C++ compiler flags
1442
1443 Use these variables to override the choices made by `configure' or to help
1444 it to find libraries and programs with nonstandard names/locations.
