1335 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1336
1337 Usage: $0 [OPTION]... [VAR=VALUE]...
1338
1339 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1340 VAR=VALUE.  See below for descriptions of some of the useful variables.
1341
1342 Defaults for the options are specified in brackets.
1343
1344 Configuration:
1345   -h, --help              display this help and exit
1346       --help=short        display options specific to this package
1347       --help=recursive    display the short help of all the included packages
1348   -V, --version           display version information and exit
1349   -q, --quiet, --silent   do not print \`checking ...' messages
1350       --cache-file=FILE   cache test results in FILE [disabled]
1351   -C, --config-cache      alias for \`--cache-file=config.cache'
1352   -n, --no-create         do not create output files
1353       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1354
1355 Installation directories:
1356   --prefix=PREFIX         install architecture-independent files in PREFIX
1357                           [$ac_default_prefix]
1358   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1359                           [PREFIX]
1360
1361 By default, \`make install' will install all the files in
1362 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1363 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1364 for instance \`--prefix=\$HOME'.
1365
1366 For better control, use the options below.
1367
1368 Fine tuning of the installation directories:
1369   --bindir=DIR            user executables [EPREFIX/bin]
1370   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1464   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1465               nonstandard directory <lib dir>
1466   LIBS        libraries to pass to the linker, e.g. -l<library>
1467   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1468               you have headers in a nonstandard directory <include dir>
1469   CPP         C preprocessor
1470   CXX         C++ compiler command
1471   CXXFLAGS    C++ compiler flags
1472
1473 Use these variables to override the choices made by `configure' or to help
1474 it to find libraries and programs with nonstandard names/locations.
