1313 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1315 Usage: $0 [OPTION]... [VAR=VALUE]...
1317 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1318 VAR=VALUE. See below for descriptions of some of the useful variables.
1320 Defaults for the options are specified in brackets.
1323 -h, --help display this help and exit
1324 --help=short display options specific to this package
1325 --help=recursive display the short help of all the included packages
1326 -V, --version display version information and exit
1327 -q, --quiet, --silent do not print \`checking ...' messages
1328 --cache-file=FILE cache test results in FILE [disabled]
1329 -C, --config-cache alias for \`--cache-file=config.cache'
1330 -n, --no-create do not create output files
1331 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1333 Installation directories:
1334 --prefix=PREFIX install architecture-independent files in PREFIX
1335 [$ac_default_prefix]
1336 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1339 By default, \`make install' will install all the files in
1340 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1341 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1342 for instance \`--prefix=\$HOME'.
1344 For better control, use the options below.
1346 Fine tuning of the installation directories:
1347 --bindir=DIR user executables [EPREFIX/bin]
1348 --sbindir=DIR system admin executables [EPREFIX/sbin]

1431 Some influential environment variables:
1432 CC C compiler command
1433 CFLAGS C compiler flags
1434 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1435 nonstandard directory <lib dir>
1436 LIBS libraries to pass to the linker, e.g. -l<library>
1437 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1438 you have headers in a nonstandard directory <include dir>
1440 CXX C++ compiler command
1441 CXXFLAGS C++ compiler flags
1443 Use these variables to override the choices made by `configure' or to help
1444 it to find libraries and programs with nonstandard names/locations.
