1309 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1311 Usage: $0 [OPTION]... [VAR=VALUE]...
1313 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1314 VAR=VALUE. See below for descriptions of some of the useful variables.
1316 Defaults for the options are specified in brackets.
1319 -h, --help display this help and exit
1320 --help=short display options specific to this package
1321 --help=recursive display the short help of all the included packages
1322 -V, --version display version information and exit
1323 -q, --quiet, --silent do not print \`checking ...' messages
1324 --cache-file=FILE cache test results in FILE [disabled]
1325 -C, --config-cache alias for \`--cache-file=config.cache'
1326 -n, --no-create do not create output files
1327 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1329 Installation directories:
1330 --prefix=PREFIX install architecture-independent files in PREFIX
1331 [$ac_default_prefix]
1332 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1335 By default, \`make install' will install all the files in
1336 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1337 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1338 for instance \`--prefix=\$HOME'.
1340 For better control, use the options below.
1342 Fine tuning of the installation directories:
1343 --bindir=DIR user executables [EPREFIX/bin]
1344 --sbindir=DIR system admin executables [EPREFIX/sbin]

1425 Some influential environment variables:
1426 CC C compiler command
1427 CFLAGS C compiler flags
1428 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1429 nonstandard directory <lib dir>
1430 LIBS libraries to pass to the linker, e.g. -l<library>
1431 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1432 you have headers in a nonstandard directory <include dir>
1434 CXX C++ compiler command
1435 CXXFLAGS C++ compiler flags
1437 Use these variables to override the choices made by `configure' or to help
1438 it to find libraries and programs with nonstandard names/locations.
