1317 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.

1319 Usage: $0 [OPTION]... [VAR=VALUE]...
1320
1321 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1322 VAR=VALUE. See below for descriptions of some of the useful variables.
1323
1324 Defaults for the options are specified in brackets.
1325
1326 Configuration:
1327 -h, --help display this help and exit
1328 --help=short display options specific to this package
1329 --help=recursive display the short help of all the included packages
1330 -V, --version display version information and exit
1331 -q, --quiet, --silent do not print \`checking ...' messages
1332 --cache-file=FILE cache test results in FILE [disabled]
1333 -C, --config-cache alias for \`--cache-file=config.cache'
1334 -n, --no-create do not create output files
1335 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1336
1337 Installation directories:
1338 --prefix=PREFIX install architecture-independent files in PREFIX
1339 [$ac_default_prefix]
1340 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1341 [PREFIX]
1342
1343 By default, \`make install' will install all the files in
1344 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1345 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1346 for instance \`--prefix=\$HOME'.
1347
1348 For better control, use the options below.
1349
1350 Fine tuning of the installation directories:
1351 --bindir=DIR user executables [EPREFIX/bin]
1352 --sbindir=DIR system admin executables [EPREFIX/sbin]

1441 --with-default-link do not use explicit linker scripts
1442 --with-cpu=CPU select code for CPU variant
1443
1444 Some influential environment variables:
1445 CC C compiler command
1446 CFLAGS C compiler flags
1447 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1448 nonstandard directory <lib dir>
1449 LIBS libraries to pass to the linker, e.g. -l<library>
1450 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1451 you have headers in a nonstandard directory <include dir>
1452 CPP C preprocessor
1453 CXX C++ compiler command
1454 CXXFLAGS C++ compiler flags
1455
1456 Use these variables to override the choices made by `configure' or to help
1457 it to find libraries and programs with nonstandard names/locations.
