1345 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1347 Usage: $0 [OPTION]... [VAR=VALUE]...
1349 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1350 VAR=VALUE. See below for descriptions of some of the useful variables.
1352 Defaults for the options are specified in brackets.
1354 Configuration:
1355 -h, --help display this help and exit
1356 --help=short display options specific to this package
1357 --help=recursive display the short help of all the included packages
1358 -V, --version display version information and exit
1359 -q, --quiet, --silent do not print \`checking ...' messages
1360 --cache-file=FILE cache test results in FILE [disabled]
1361 -C, --config-cache alias for \`--cache-file=config.cache'
1362 -n, --no-create do not create output files
1363 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1365 Installation directories:
1366 --prefix=PREFIX install architecture-independent files in PREFIX
1367 [$ac_default_prefix]
1368 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1369 [PREFIX]
1371 By default, \`make install' will install all the files in
1372 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1373 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1374 for instance \`--prefix=\$HOME'.
1376 For better control, use the options below.
1378 Fine tuning of the installation directories:
1379 --bindir=DIR user executables [EPREFIX/bin]
1380 --sbindir=DIR system admin executables [EPREFIX/sbin]
1381 --libexecdir=DIR program executables [EPREFIX/libexec]

1484 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1485 nonstandard directory <lib dir>
1486 LIBS libraries to pass to the linker, e.g. -l<library>
1487 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1488 you have headers in a nonstandard directory <include dir>
1489 CPP C preprocessor
1490 CXX C++ compiler command
1491 CXXFLAGS C++ compiler flags
1493 Use these variables to override the choices made by `configure' or to help
1494 it to find libraries and programs with nonstandard names/locations.
