1334 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1335
1336 Usage: $0 [OPTION]... [VAR=VALUE]...
1337
1338 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1339 VAR=VALUE.  See below for descriptions of some of the useful variables.
1340
1341 Defaults for the options are specified in brackets.
1342
1343 Configuration:
1344   -h, --help              display this help and exit
1345       --help=short        display options specific to this package
1346       --help=recursive    display the short help of all the included packages
1347   -V, --version           display version information and exit
1348   -q, --quiet, --silent   do not print \`checking ...' messages
1349       --cache-file=FILE   cache test results in FILE [disabled]
1350   -C, --config-cache      alias for \`--cache-file=config.cache'
1351   -n, --no-create         do not create output files
1352       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1353
1354 Installation directories:
1355   --prefix=PREFIX         install architecture-independent files in PREFIX
1356                           [$ac_default_prefix]
1357   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1358                           [PREFIX]
1359
1360 By default, \`make install' will install all the files in
1361 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1362 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1363 for instance \`--prefix=\$HOME'.
1364
1365 For better control, use the options below.
1366
1367 Fine tuning of the installation directories:
1368   --bindir=DIR            user executables [EPREFIX/bin]
1369   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1462   CFLAGS      C compiler flags
1463   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1464               nonstandard directory <lib dir>
1465   LIBS        libraries to pass to the linker, e.g. -l<library>
1466   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1467               you have headers in a nonstandard directory <include dir>
1468   CPP         C preprocessor
1469   CXX         C++ compiler command
1470   CXXFLAGS    C++ compiler flags
1471
1472 Use these variables to override the choices made by `configure' or to help
1473 it to find libraries and programs with nonstandard names/locations.
