1321 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1322
1323 Usage: $0 [OPTION]... [VAR=VALUE]...
1324
1325 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1326 VAR=VALUE.  See below for descriptions of some of the useful variables.
1327
1328 Defaults for the options are specified in brackets.
1329
1330 Configuration:
1331   -h, --help              display this help and exit
1332       --help=short        display options specific to this package
1333       --help=recursive    display the short help of all the included packages
1334   -V, --version           display version information and exit
1335   -q, --quiet, --silent   do not print \`checking ...' messages
1336       --cache-file=FILE   cache test results in FILE [disabled]
1337   -C, --config-cache      alias for \`--cache-file=config.cache'
1338   -n, --no-create         do not create output files
1339       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1340
1341 Installation directories:
1342   --prefix=PREFIX         install architecture-independent files in PREFIX
1343                           [$ac_default_prefix]
1344   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1345                           [PREFIX]
1346
1347 By default, \`make install' will install all the files in
1348 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1349 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1350 for instance \`--prefix=\$HOME'.
1351
1352 For better control, use the options below.

1446   CFLAGS      C compiler flags
1447   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1448               nonstandard directory <lib dir>
1449   LIBS        libraries to pass to the linker, e.g. -l<library>
1450   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1451               you have headers in a nonstandard directory <include dir>
1452   CPP         C preprocessor
1453   CXX         C++ compiler command
1454   CXXFLAGS    C++ compiler flags
1455
1456 Use these variables to override the choices made by `configure' or to help
1457 it to find libraries and programs with nonstandard names/locations.
