1339 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1341 Usage: $0 [OPTION]... [VAR=VALUE]...
1343 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1344 VAR=VALUE. See below for descriptions of some of the useful variables.
1346 Defaults for the options are specified in brackets.
1349 -h, --help display this help and exit
1350 --help=short display options specific to this package
1351 --help=recursive display the short help of all the included packages
1352 -V, --version display version information and exit
1353 -q, --quiet, --silent do not print \`checking ...' messages
1354 --cache-file=FILE cache test results in FILE [disabled]
1355 -C, --config-cache alias for \`--cache-file=config.cache'
1356 -n, --no-create do not create output files
1357 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1359 Installation directories:
1360 --prefix=PREFIX install architecture-independent files in PREFIX
1361 [$ac_default_prefix]
1362 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1365 By default, \`make install' will install all the files in
1366 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1367 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1368 for instance \`--prefix=\$HOME'.
1370 For better control, use the options below.
1372 Fine tuning of the installation directories:
1373 --bindir=DIR user executables [EPREFIX/bin]
1374 --sbindir=DIR system admin executables [EPREFIX/sbin]

1470 Some influential environment variables:
1471 CC C compiler command
1472 CFLAGS C compiler flags
1473 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1474 nonstandard directory <lib dir>
1475 LIBS libraries to pass to the linker, e.g. -l<library>
1476 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1477 you have headers in a nonstandard directory <include dir>
1479 CXX C++ compiler command
1480 CXXFLAGS C++ compiler flags
1482 Use these variables to override the choices made by `configure' or to help
