1315 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1317 Usage: $0 [OPTION]... [VAR=VALUE]...
1319 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1320 VAR=VALUE. See below for descriptions of some of the useful variables.
1322 Defaults for the options are specified in brackets.
1324 Configuration:
1325 -h, --help display this help and exit
1326 --help=short display options specific to this package
1327 --help=recursive display the short help of all the included packages
1328 -V, --version display version information and exit
1329 -q, --quiet, --silent do not print \`checking ...' messages
1330 --cache-file=FILE cache test results in FILE [disabled]
1331 -C, --config-cache alias for \`--cache-file=config.cache'
1332 -n, --no-create do not create output files
1333 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1335 Installation directories:
1336 --prefix=PREFIX install architecture-independent files in PREFIX
1337 [$ac_default_prefix]
1338 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1339 [PREFIX]
1341 By default, \`make install' will install all the files in
1342 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1343 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1344 for instance \`--prefix=\$HOME'.
1346 For better control, use the options below.
1348 Fine tuning of the installation directories:
1349 --bindir=DIR user executables [EPREFIX/bin]
1350 --sbindir=DIR system admin executables [EPREFIX/sbin]
1351 --libexecdir=DIR program executables [EPREFIX/libexec]

1423 --disable-nscd library functions will not contact the nscd daemon
1424 --enable-pt_chown Enable building and installing pt_chown
1426 Optional Packages:
1427 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1428 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1429 --with-pkgversion=PKG Use PKG in the version string in place of "GNU libc"

1438 /usr/src/linux/include) [default=compiler default]
1439 --with-default-link do not use explicit linker scripts
1440 --with-cpu=CPU select code for CPU variant
1442 Some influential environment variables:
1443 CC C compiler command
1444 CFLAGS C compiler flags
1445 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1446 nonstandard directory <lib dir>
1447 LIBS libraries to pass to the linker, e.g. -l<library>
1448 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1449 you have headers in a nonstandard directory <include dir>
1450 CPP C preprocessor
1451 CXX C++ compiler command
1452 CXXFLAGS C++ compiler flags
1454 Use these variables to override the choices made by `configure' or to help
1455 it to find libraries and programs with nonstandard names/locations.
