1319 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1320
1321 Usage: $0 [OPTION]... [VAR=VALUE]...
1322
1323 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1324 VAR=VALUE. See below for descriptions of some of the useful variables.
1325
1326 Defaults for the options are specified in brackets.
1327
1328 Configuration:
1329 -h, --help display this help and exit
1330 --help=short display options specific to this package
1331 --help=recursive display the short help of all the included packages
1332 -V, --version display version information and exit
1333 -q, --quiet, --silent do not print \`checking ...' messages
1334 --cache-file=FILE cache test results in FILE [disabled]
1335 -C, --config-cache alias for \`--cache-file=config.cache'
1336 -n, --no-create do not create output files
1337 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1338
1339 Installation directories:
1340 --prefix=PREFIX install architecture-independent files in PREFIX
1341 [$ac_default_prefix]
1342 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1343 [PREFIX]
1344
1345 By default, \`make install' will install all the files in
1346 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1347 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1348 for instance \`--prefix=\$HOME'.
1349
1350 For better control, use the options below.
1351
1352 Fine tuning of the installation directories:
1353 --bindir=DIR user executables [EPREFIX/bin]
1354 --sbindir=DIR system admin executables [EPREFIX/sbin]
1355 --libexecdir=DIR program executables [EPREFIX/libexec]

1424 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1425 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1426 --with-pkgversion=PKG Use PKG in the version string in place of "GNU libc"
1427 --with-bugurl=URL Direct users to URL to report a bug

1435 /usr/src/linux/include) [default=compiler default]
1436 --with-default-link do not use explicit linker scripts
1437 --with-cpu=CPU select code for CPU variant
1438
1439 Some influential environment variables:
1440 CC C compiler command
1441 CFLAGS C compiler flags
1442 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1443 nonstandard directory <lib dir>
1444 LIBS libraries to pass to the linker, e.g. -l<library>
1445 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1446 you have headers in a nonstandard directory <include dir>
1447 CPP C preprocessor
1448 CXX C++ compiler command
1449 CXXFLAGS C++ compiler flags
1450
1451 Use these variables to override the choices made by `configure' or to help
1452 it to find libraries and programs with nonstandard names/locations.
