1247 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1248
1249 Usage: $0 [OPTION]... [VAR=VALUE]...
1250
1251 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1252 VAR=VALUE.  See below for descriptions of some of the useful variables.
1253
1254 Defaults for the options are specified in brackets.
1255
1256 Configuration:
1257   -h, --help              display this help and exit
1258       --help=short        display options specific to this package
1259       --help=recursive    display the short help of all the included packages
1260   -V, --version           display version information and exit
1261   -q, --quiet, --silent   do not print \`checking...' messages
1262       --cache-file=FILE   cache test results in FILE [disabled]
1263   -C, --config-cache      alias for \`--cache-file=config.cache'
1264   -n, --no-create         do not create output files
1265       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1266
1267 Installation directories:
1268   --prefix=PREFIX         install architecture-independent files in PREFIX
1269                           [$ac_default_prefix]
1270   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1271                           [PREFIX]
1272
1273 By default, \`make install' will install all the files in
1274 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1275 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1276 for instance \`--prefix=\$HOME'.
1277
1278 For better control, use the options below.

1280 Fine tuning of the installation directories:
1281   --bindir=DIR           user executables [EPREFIX/bin]
1282   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1364 Some influential environment variables:
1365   CC          C compiler command
1366   CFLAGS      C compiler flags
1367   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1368               nonstandard directory <lib dir>
1369   LIBS        libraries to pass to the linker, e.g. -l<library>
1370   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1371               you have headers in a nonstandard directory <include dir>
1372   CPP         C preprocessor
1373   CXX         C++ compiler command
1374   CXXFLAGS    C++ compiler flags
