1316 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.

1318 Usage: $0 [OPTION]... [VAR=VALUE]...
1319
1320 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1321 VAR=VALUE. See below for descriptions of some of the useful variables.
1322
1323 Defaults for the options are specified in brackets.
1324
1325 Configuration:
1326 -h, --help display this help and exit
1327 --help=short display options specific to this package
1328 --help=recursive display the short help of all the included packages
1329 -V, --version display version information and exit
1330 -q, --quiet, --silent do not print \`checking ...' messages
1331 --cache-file=FILE cache test results in FILE [disabled]
1332 -C, --config-cache alias for \`--cache-file=config.cache'
1333 -n, --no-create do not create output files
1334 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1335
1336 Installation directories:
1337 --prefix=PREFIX install architecture-independent files in PREFIX
1338 [$ac_default_prefix]
1339 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1340 [PREFIX]
1341
1342 By default, \`make install' will install all the files in
1343 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1344 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1345 for instance \`--prefix=\$HOME'.
1346
1347 For better control, use the options below.
1348
1349 Fine tuning of the installation directories:
1350 --bindir=DIR user executables [EPREFIX/bin]
1351 --sbindir=DIR system admin executables [EPREFIX/sbin]

1440 --with-default-link do not use explicit linker scripts
1441 --with-cpu=CPU select code for CPU variant
1442
1443 Some influential environment variables:
1444 CC C compiler command
1445 CFLAGS C compiler flags
1446 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1447 nonstandard directory <lib dir>
1448 LIBS libraries to pass to the linker, e.g. -l<library>
1449 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1450 you have headers in a nonstandard directory <include dir>
1451 CPP C preprocessor
1452 CXX C++ compiler command
1453 CXXFLAGS C++ compiler flags
1454
1455 Use these variables to override the choices made by `configure' or to help
1456 it to find libraries and programs with nonstandard names/locations.
