1314 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1315
1316 Usage: $0 [OPTION]... [VAR=VALUE]...
1317
1318 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1319 VAR=VALUE. See below for descriptions of some of the useful variables.
1320
1321 Defaults for the options are specified in brackets.
1322
1323 Configuration:
1324 -h, --help display this help and exit
1325 --help=short display options specific to this package
1326 --help=recursive display the short help of all the included packages
1327 -V, --version display version information and exit
1328 -q, --quiet, --silent do not print \`checking ...' messages
1329 --cache-file=FILE cache test results in FILE [disabled]
1330 -C, --config-cache alias for \`--cache-file=config.cache'
1331 -n, --no-create do not create output files
1332 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1333
1334 Installation directories:
1335 --prefix=PREFIX install architecture-independent files in PREFIX
1336 [$ac_default_prefix]
1337 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1338 [PREFIX]
1339
1340 By default, \`make install' will install all the files in
1341 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1342 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1343 for instance \`--prefix=\$HOME'.
1344
1345 For better control, use the options below.
1346
1347 Fine tuning of the installation directories:
1348 --bindir=DIR user executables [EPREFIX/bin]
1349 --sbindir=DIR system admin executables [EPREFIX/sbin]
1350 --libexecdir=DIR program executables [EPREFIX/libexec]

1420
1421 Optional Packages:

1434 --with-default-link do not use explicit linker scripts
1435 --with-cpu=CPU select code for CPU variant
1436
1437 Some influential environment variables:
1438 CC C compiler command
1439 CFLAGS C compiler flags
1440 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1441 nonstandard directory <lib dir>
1442 LIBS libraries to pass to the linker, e.g. -l<library>
1443 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1444 you have headers in a nonstandard directory <include dir>
1445 CPP C preprocessor
1446 CXX C++ compiler command
1447 CXXFLAGS C++ compiler flags
1448
1449 Use these variables to override the choices made by `configure' or to help
1450 it to find libraries and programs with nonstandard names/locations.
