1343 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1344
1345 Usage: $0 [OPTION]... [VAR=VALUE]...
1346
1347 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1348 VAR=VALUE.  See below for descriptions of some of the useful variables.
1349
1350 Defaults for the options are specified in brackets.
1351
1352 Configuration:
1353   -h, --help              display this help and exit
1354       --help=short        display options specific to this package
1355       --help=recursive    display the short help of all the included packages
1356   -V, --version           display version information and exit
1357   -q, --quiet, --silent   do not print \`checking ...' messages
1358       --cache-file=FILE   cache test results in FILE [disabled]
1359   -C, --config-cache      alias for \`--cache-file=config.cache'
1360   -n, --no-create         do not create output files
1361       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1362
1363 Installation directories:
1364   --prefix=PREFIX         install architecture-independent files in PREFIX
1365                           [$ac_default_prefix]
1366   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1367                           [PREFIX]
1368
1369 By default, \`make install' will install all the files in
1370 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1371 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1372 for instance \`--prefix=\$HOME'.
1373
1374 For better control, use the options below.
1375
1376 Fine tuning of the installation directories:
1377   --bindir=DIR            user executables [EPREFIX/bin]
1378   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1379   --libexecdir=DIR        program executables [EPREFIX/libexec]
1380   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1381   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
1382   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]

1462               nonstandard directory <lib dir>
1463   LIBS        libraries to pass to the linker, e.g. -l<library>
1464   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1465               you have headers in a nonstandard directory <include dir>
1466   CPP         C preprocessor
1467   CXX         C++ compiler command
1468   CXXFLAGS    C++ compiler flags
