1308 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1309
1310 Usage: $0 [OPTION]... [VAR=VALUE]...
1311
1312 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1313 VAR=VALUE. See below for descriptions of some of the useful variables.
1314
1315 Defaults for the options are specified in brackets.
1316
1317 Configuration:
1318 -h, --help display this help and exit
1319 --help=short display options specific to this package
1320 --help=recursive display the short help of all the included packages
1321 -V, --version display version information and exit
1322 -q, --quiet, --silent do not print \`checking ...' messages
1323 --cache-file=FILE cache test results in FILE [disabled]
1324 -C, --config-cache alias for \`--cache-file=config.cache'
1325 -n, --no-create do not create output files
1326 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1327
1328 Installation directories:
1329 --prefix=PREFIX install architecture-independent files in PREFIX
1330 [$ac_default_prefix]
1331 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1332 [PREFIX]
1333
1334 By default, \`make install' will install all the files in
1335 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1336 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1337 for instance \`--prefix=\$HOME'.
1338
1339 For better control, use the options below.
1340
1341 Fine tuning of the installation directories:
1342 --bindir=DIR user executables [EPREFIX/bin]
1343 --sbindir=DIR system admin executables [EPREFIX/sbin]
1344 --libexecdir=DIR program executables [EPREFIX/libexec]

1409
1410 Optional Packages:
1411 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1412 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1413 --with-gd=DIR find libgd include dir and library with prefix DIR
1414 --with-gd-include=DIR find libgd include files in DIR
1415 --with-gd-lib=DIR find libgd library files in DIR
1416 --with-fp if using floating-point hardware [default=yes]
1417 --with-binutils=PATH specify location of binutils (as and ld)

1420 /usr/src/linux/include) [default=compiler default]
1421 --with-default-link do not use explicit linker scripts
1422 --with-cpu=CPU select code for CPU variant
1423
1424 Some influential environment variables:
1425 CC C compiler command
1426 CFLAGS C compiler flags
1427 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1428 nonstandard directory <lib dir>
1429 LIBS libraries to pass to the linker, e.g. -l<library>
1430 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1431 you have headers in a nonstandard directory <include dir>
1432 CPP C preprocessor
1433 CXX C++ compiler command
1434 CXXFLAGS C++ compiler flags
1435
1436 Use these variables to override the choices made by `configure' or to help
1437 it to find libraries and programs with nonstandard names/locations.
