1283 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1284
1285 Usage: $0 [OPTION]... [VAR=VALUE]...
1286
1287 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1288 VAR=VALUE.  See below for descriptions of some of the useful variables.
1289
1290 Defaults for the options are specified in brackets.
1291
1292 Configuration:
1293   -h, --help              display this help and exit
1294       --help=short        display options specific to this package
1295       --help=recursive    display the short help of all the included packages
1296   -V, --version           display version information and exit
1297   -q, --quiet, --silent   do not print \`checking...' messages
1298       --cache-file=FILE   cache test results in FILE [disabled]
1299   -C, --config-cache      alias for \`--cache-file=config.cache'
1300   -n, --no-create         do not create output files
1301       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1302
1303 Installation directories:
1304   --prefix=PREFIX         install architecture-independent files in PREFIX
1305                           [$ac_default_prefix]
1306   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1307                           [PREFIX]
1308
1309 By default, \`make install' will install all the files in
1310 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1311 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1312 for instance \`--prefix=\$HOME'.
1313
1314 For better control, use the options below.

1316 Fine tuning of the installation directories:
1317   --bindir=DIR           user executables [EPREFIX/bin]
1318   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1400 Some influential environment variables:
1401   CC          C compiler command
1402   CFLAGS      C compiler flags
1403   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1404               nonstandard directory <lib dir>
1405   LIBS        libraries to pass to the linker, e.g. -l<library>
1406   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1407               you have headers in a nonstandard directory <include dir>
1408   CPP         C preprocessor
1409   CXX         C++ compiler command
1410   CXXFLAGS    C++ compiler flags
