1314 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1315
1316 Usage: $0 [OPTION]... [VAR=VALUE]...
1317
1318 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1319 VAR=VALUE.  See below for descriptions of some of the useful variables.
1320
1321 Defaults for the options are specified in brackets.
1322
1323 Configuration:
1324   -h, --help              display this help and exit
1325       --help=short        display options specific to this package
1326       --help=recursive    display the short help of all the included packages
1327   -V, --version           display version information and exit
1328   -q, --quiet, --silent   do not print \`checking ...' messages
1329       --cache-file=FILE   cache test results in FILE [disabled]
1330   -C, --config-cache      alias for \`--cache-file=config.cache'
1331   -n, --no-create         do not create output files
1332       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1333
1334 Installation directories:
1335   --prefix=PREFIX         install architecture-independent files in PREFIX
1336                           [$ac_default_prefix]
1337   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1338                           [PREFIX]
1339
1340 By default, \`make install' will install all the files in
1341 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1342 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1343 for instance \`--prefix=\$HOME'.
1344
1345 For better control, use the options below.
1346
1347 Fine tuning of the installation directories:
1348   --bindir=DIR            user executables [EPREFIX/bin]
1349   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1434   CFLAGS      C compiler flags
1435   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1436               nonstandard directory <lib dir>
1437   LIBS        libraries to pass to the linker, e.g. -l<library>
1438   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1439               you have headers in a nonstandard directory <include dir>
1440   CPP         C preprocessor
1441   CXX         C++ compiler command
1442   CXXFLAGS    C++ compiler flags
1443
1444 Use these variables to override the choices made by `configure' or to help
1445 it to find libraries and programs with nonstandard names/locations.
