1335 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1337 Usage: $0 [OPTION]... [VAR=VALUE]...
1339 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1340 VAR=VALUE. See below for descriptions of some of the useful variables.
1342 Defaults for the options are specified in brackets.
1345 -h, --help display this help and exit
1346 --help=short display options specific to this package
1347 --help=recursive display the short help of all the included packages
1348 -V, --version display version information and exit
1349 -q, --quiet, --silent do not print \`checking ...' messages
1350 --cache-file=FILE cache test results in FILE [disabled]
1351 -C, --config-cache alias for \`--cache-file=config.cache'
1352 -n, --no-create do not create output files
1353 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1355 Installation directories:
1356 --prefix=PREFIX install architecture-independent files in PREFIX
1357 [$ac_default_prefix]
1358 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1361 By default, \`make install' will install all the files in
1362 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1363 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1364 for instance \`--prefix=\$HOME'.
1366 For better control, use the options below.
1368 Fine tuning of the installation directories:
1369 --bindir=DIR user executables [EPREFIX/bin]
1370 --sbindir=DIR system admin executables [EPREFIX/sbin]

1466 Some influential environment variables:
1467 CC C compiler command
1468 CFLAGS C compiler flags
1469 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1470 nonstandard directory <lib dir>
1471 LIBS libraries to pass to the linker, e.g. -l<library>
1472 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1473 you have headers in a nonstandard directory <include dir>
1475 CXX C++ compiler command
1476 CXXFLAGS C++ compiler flags
1478 Use these variables to override the choices made by `configure' or to help
1479 it to find libraries and programs with nonstandard names/locations.
