1312 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1313
1314 Usage: $0 [OPTION]... [VAR=VALUE]...
1315
1316 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1317 VAR=VALUE. See below for descriptions of some of the useful variables.
1318
1319 Defaults for the options are specified in brackets.
1320
1321 Configuration:
1322 -h, --help display this help and exit
1323 --help=short display options specific to this package
1324 --help=recursive display the short help of all the included packages
1325 -V, --version display version information and exit
1326 -q, --quiet, --silent do not print \`checking ...' messages
1327 --cache-file=FILE cache test results in FILE [disabled]
1328 -C, --config-cache alias for \`--cache-file=config.cache'
1329 -n, --no-create do not create output files
1330 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1331
1332 Installation directories:
1333 --prefix=PREFIX install architecture-independent files in PREFIX
1334 [$ac_default_prefix]
1335 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1336 [PREFIX]
1337
1338 By default, \`make install' will install all the files in
1339 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1340 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1341 for instance \`--prefix=\$HOME'.
1342
1343 For better control, use the options below.
1344
1345 Fine tuning of the installation directories:
1346 --bindir=DIR user executables [EPREFIX/bin]
1347 --sbindir=DIR system admin executables [EPREFIX/sbin]
1348 --libexecdir=DIR program executables [EPREFIX/libexec]

1414
1415 Optional Packages:
1416 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1417 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1418 --with-gd=DIR find libgd include dir and library with prefix DIR
1419 --with-gd-include=DIR find libgd include files in DIR

1425 /usr/src/linux/include) [default=compiler default]
1426 --with-default-link do not use explicit linker scripts
1427 --with-cpu=CPU select code for CPU variant
1428
1429 Some influential environment variables:
1430 CC C compiler command
1431 CFLAGS C compiler flags
1432 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1433 nonstandard directory <lib dir>
1434 LIBS libraries to pass to the linker, e.g. -l<library>
1435 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1436 you have headers in a nonstandard directory <include dir>
1437 CPP C preprocessor
1438 CXX C++ compiler command
1439 CXXFLAGS C++ compiler flags
1440
1441 Use these variables to override the choices made by `configure' or to help
1442 it to find libraries and programs with nonstandard names/locations.
