1288 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1289
1290 Usage: $0 [OPTION]... [VAR=VALUE]...
1291
1292 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1293 VAR=VALUE.  See below for descriptions of some of the useful variables.
1294
1295 Defaults for the options are specified in brackets.
1296
1297 Configuration:
1298   -h, --help              display this help and exit
1299       --help=short        display options specific to this package
1300       --help=recursive    display the short help of all the included packages
1301   -V, --version           display version information and exit
1302   -q, --quiet, --silent   do not print \`checking...' messages
1303       --cache-file=FILE   cache test results in FILE [disabled]
1304   -C, --config-cache      alias for \`--cache-file=config.cache'
1305   -n, --no-create         do not create output files
1306       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1307
1308 Installation directories:
1309   --prefix=PREFIX         install architecture-independent files in PREFIX
1310                           [$ac_default_prefix]
1311   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1312                           [PREFIX]
1313
1314 By default, \`make install' will install all the files in
1315 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1316 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1317 for instance \`--prefix=\$HOME'.
1318
1319 For better control, use the options below.

1322   --bindir=DIR           user executables [EPREFIX/bin]
1323   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1410 Some influential environment variables:
1411   CC          C compiler command
1412   CFLAGS      C compiler flags
1413   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1414               nonstandard directory <lib dir>
1415   LIBS        libraries to pass to the linker, e.g. -l<library>
1416   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if

1419   CXX         C++ compiler command
1420   CXXFLAGS    C++ compiler flags
