1284 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1285
1286 Usage: $0 [OPTION]... [VAR=VALUE]...
1287
1288 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1289 VAR=VALUE.  See below for descriptions of some of the useful variables.
1290
1291 Defaults for the options are specified in brackets.
1292
1293 Configuration:
1294   -h, --help              display this help and exit
1295       --help=short        display options specific to this package
1296       --help=recursive    display the short help of all the included packages
1297   -V, --version           display version information and exit
1298   -q, --quiet, --silent   do not print \`checking...' messages
1299       --cache-file=FILE   cache test results in FILE [disabled]
1300   -C, --config-cache      alias for \`--cache-file=config.cache'
1301   -n, --no-create         do not create output files
1302       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1303
1304 Installation directories:
1305   --prefix=PREFIX         install architecture-independent files in PREFIX
1306                           [$ac_default_prefix]
1307   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1308                           [PREFIX]
1309
1310 By default, \`make install' will install all the files in
1311 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1312 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1313 for instance \`--prefix=\$HOME'.
1314
1315 For better control, use the options below.

1318   --bindir=DIR           user executables [EPREFIX/bin]
1319   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1401 Some influential environment variables:
1402   CC          C compiler command
1403   CFLAGS      C compiler flags
1404   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1405               nonstandard directory <lib dir>
1406   LIBS        libraries to pass to the linker, e.g. -l<library>
1407   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1408               you have headers in a nonstandard directory <include dir>
1409   CPP         C preprocessor
1410   CXX         C++ compiler command
1411   CXXFLAGS    C++ compiler flags
