1346 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1347
1348 Usage: $0 [OPTION]... [VAR=VALUE]...
1349
1350 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1351 VAR=VALUE.  See below for descriptions of some of the useful variables.
1352
1353 Defaults for the options are specified in brackets.
1354
1355 Configuration:
1356   -h, --help              display this help and exit
1357       --help=short        display options specific to this package
1358       --help=recursive    display the short help of all the included packages
1359   -V, --version           display version information and exit
1360   -q, --quiet, --silent   do not print \`checking...' messages
1361       --cache-file=FILE   cache test results in FILE [disabled]
1362   -C, --config-cache      alias for \`--cache-file=config.cache'
1363   -n, --no-create         do not create output files
1364       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1365
1366 Installation directories:
1367   --prefix=PREFIX         install architecture-independent files in PREFIX
1368                           [$ac_default_prefix]
1369   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1370                           [PREFIX]
1371
1372 By default, \`make install' will install all the files in
1373 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1374 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1375 for instance \`--prefix=\$HOME'.
1376
1377 For better control, use the options below.
1378
1379 Fine tuning of the installation directories:
1380   --bindir=DIR            user executables [EPREFIX/bin]
1381   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1477   CPP         C preprocessor
1478   CXX         C++ compiler command
1479   CXXFLAGS    C++ compiler flags
