1314 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1316 Usage: $0 [OPTION]... [VAR=VALUE]...
1318 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1319 VAR=VALUE. See below for descriptions of some of the useful variables.
1321 Defaults for the options are specified in brackets.
1323 Configuration:
1324 -h, --help display this help and exit
1325 --help=short display options specific to this package
1326 --help=recursive display the short help of all the included packages
1327 -V, --version display version information and exit
1328 -q, --quiet, --silent do not print \`checking ...' messages
1329 --cache-file=FILE cache test results in FILE [disabled]
1330 -C, --config-cache alias for \`--cache-file=config.cache'
1331 -n, --no-create do not create output files
1332 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1334 Installation directories:
1335 --prefix=PREFIX install architecture-independent files in PREFIX
1336 [$ac_default_prefix]
1337 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1338 [PREFIX]
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'.
1345 For better control, use the options below.
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]
1351 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1352 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

1415 --disable-build-nscd disable building and installing the nscd daemon
1416 --disable-nscd library functions will not contact the nscd daemon
1418 Optional Packages:
1419 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1420 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1421 --with-gd=DIR find libgd include dir and library with prefix DIR
1422 --with-gd-include=DIR find libgd include files in DIR
1423 --with-gd-lib=DIR find libgd library files in DIR
1424 --with-fp if using floating-point hardware [default=yes]
1425 --with-binutils=PATH specify location of binutils (as and ld)
1426 --with-selinux if building with SELinux support
1427 --with-headers=PATH location of system headers to use (for example
1428 /usr/src/linux/include) [default=compiler default]
1429 --with-default-link do not use explicit linker scripts
1430 --with-cpu=CPU select code for CPU variant
1432 Some influential environment variables:
1433 CC C compiler command
1434 CFLAGS C compiler flags
1435 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1436 nonstandard directory <lib dir>
1437 LIBS libraries to pass to the linker, e.g. -l<library>
1438 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1439 you have headers in a nonstandard directory <include dir>
1440 CPP C preprocessor
1441 CXX C++ compiler command
1442 CXXFLAGS C++ compiler flags
1444 Use these variables to override the choices made by `configure' or to help
1445 it to find libraries and programs with nonstandard names/locations.
