1341 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1342
1343 Usage: $0 [OPTION]... [VAR=VALUE]...
1344
1345 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1346 VAR=VALUE. See below for descriptions of some of the useful variables.
1347
1348 Defaults for the options are specified in brackets.
1349
1350 Configuration:
1351 -h, --help display this help and exit
1352 --help=short display options specific to this package
1353 --help=recursive display the short help of all the included packages
1354 -V, --version display version information and exit
1355 -q, --quiet, --silent do not print \`checking ...' messages
1356 --cache-file=FILE cache test results in FILE [disabled]
1357 -C, --config-cache alias for \`--cache-file=config.cache'
1358 -n, --no-create do not create output files
1359 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1360
1361 Installation directories:
1362 --prefix=PREFIX install architecture-independent files in PREFIX
1363 [$ac_default_prefix]
1364 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1365 [PREFIX]
1366
1367 By default, \`make install' will install all the files in
1368 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1369 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1370 for instance \`--prefix=\$HOME'.
1371
1372 For better control, use the options below.
1373
1374 Fine tuning of the installation directories:
1375 --bindir=DIR user executables [EPREFIX/bin]
1376 --sbindir=DIR system admin executables [EPREFIX/sbin]

1444 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1445 --with-gd=DIR find libgd include dir and library with prefix DIR

1447 --with-gd-lib=DIR find libgd library files in DIR
1448 --with-fp if using floating-point hardware [default=yes]
1449 --with-binutils=PATH specify location of binutils (as and ld)

1452 /usr/src/linux/include) [default=compiler default]
1453 --with-default-link do not use explicit linker scripts
1454 --with-cpu=CPU select code for CPU variant
1455
1456 Some influential environment variables:
1457 CC C compiler command
1458 CFLAGS C compiler flags
1459 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1460 nonstandard directory <lib dir>
1461 LIBS libraries to pass to the linker, e.g. -l<library>
1462 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1463 you have headers in a nonstandard directory <include dir>
1464 CPP C preprocessor
1465 CXX C++ compiler command
1466 CXXFLAGS C++ compiler flags
1467
1468 Use these variables to override the choices made by `configure' or to help
1469 it to find libraries and programs with nonstandard names/locations.
