1332 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1333
1334 Usage: $0 [OPTION]... [VAR=VALUE]...
1335
1336 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1337 VAR=VALUE.  See below for descriptions of some of the useful variables.
1338
1339 Defaults for the options are specified in brackets.
1340
1341 Configuration:
1342   -h, --help              display this help and exit
1343       --help=short        display options specific to this package
1344       --help=recursive    display the short help of all the included packages
1345   -V, --version           display version information and exit
1346   -q, --quiet, --silent   do not print \`checking ...' messages
1347       --cache-file=FILE   cache test results in FILE [disabled]
1348   -C, --config-cache      alias for \`--cache-file=config.cache'
1349   -n, --no-create         do not create output files
1350       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1351
1352 Installation directories:
1353   --prefix=PREFIX         install architecture-independent files in PREFIX
1354                           [$ac_default_prefix]
1355   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1356                           [PREFIX]
1357
1358 By default, \`make install' will install all the files in
1359 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1360 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1361 for instance \`--prefix=\$HOME'.
1362
1363 For better control, use the options below.
1364
1365 Fine tuning of the installation directories:
1366   --bindir=DIR            user executables [EPREFIX/bin]

1460   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1461               nonstandard directory <lib dir>
1462   LIBS        libraries to pass to the linker, e.g. -l<library>
1463   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

1465   CPP         C preprocessor
1466   CXX         C++ compiler command
1467   CXXFLAGS    C++ compiler flags
1468
1469 Use these variables to override the choices made by `configure' or to help
1470 it to find libraries and programs with nonstandard names/locations.
