1285 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1286
1287 Usage: $0 [OPTION]... [VAR=VALUE]...
1288
1289 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1290 VAR=VALUE.  See below for descriptions of some of the useful variables.
1291
1292 Defaults for the options are specified in brackets.
1293
1294 Configuration:
1295   -h, --help              display this help and exit
1296       --help=short        display options specific to this package
1297       --help=recursive    display the short help of all the included packages
1298   -V, --version           display version information and exit
1299   -q, --quiet, --silent   do not print \`checking...' messages
1300       --cache-file=FILE   cache test results in FILE [disabled]
1301   -C, --config-cache      alias for \`--cache-file=config.cache'
1302   -n, --no-create         do not create output files
1303       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1304
1305 Installation directories:
1306   --prefix=PREFIX         install architecture-independent files in PREFIX
1307                           [$ac_default_prefix]
1308   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1309                           [PREFIX]
1310
1311 By default, \`make install' will install all the files in
1312 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1313 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1314 for instance \`--prefix=\$HOME'.
1315
1316 For better control, use the options below.

1319   --bindir=DIR           user executables [EPREFIX/bin]
1320   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1402 Some influential environment variables:
1403   CC          C compiler command
1404   CFLAGS      C compiler flags
1405   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1406               nonstandard directory <lib dir>
1407   LIBS        libraries to pass to the linker, e.g. -l<library>
1408   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1409               you have headers in a nonstandard directory <include dir>
1410   CPP         C preprocessor
1411   CXX         C++ compiler command
1412   CXXFLAGS    C++ compiler flags
