1348 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1350 Usage: $0 [OPTION]... [VAR=VALUE]...
1352 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1353 VAR=VALUE. See below for descriptions of some of the useful variables.
1355 Defaults for the options are specified in brackets.
1358 -h, --help display this help and exit
1359 --help=short display options specific to this package
1360 --help=recursive display the short help of all the included packages
1361 -V, --version display version information and exit
1362 -q, --quiet, --silent do not print \`checking ...' messages
1363 --cache-file=FILE cache test results in FILE [disabled]
1364 -C, --config-cache alias for \`--cache-file=config.cache'
1365 -n, --no-create do not create output files
1366 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1368 Installation directories:
1369 --prefix=PREFIX install architecture-independent files in PREFIX
1370 [$ac_default_prefix]
1371 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1374 By default, \`make install' will install all the files in
1375 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1376 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1377 for instance \`--prefix=\$HOME'.
1379 For better control, use the options below.

1490 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1491 nonstandard directory <lib dir>
1492 LIBS libraries to pass to the linker, e.g. -l<library>
1493 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1494 you have headers in a nonstandard directory <include dir>
1496 CXX C++ compiler command
1497 CXXFLAGS C++ compiler flags
1499 Use these variables to override the choices made by `configure' or to help
1500 it to find libraries and programs with nonstandard names/locations.
