1343 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1345 Usage: $0 [OPTION]... [VAR=VALUE]...
1347 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1348 VAR=VALUE. See below for descriptions of some of the useful variables.
1350 Defaults for the options are specified in brackets.
1352 Configuration:
1353 -h, --help display this help and exit
1354 --help=short display options specific to this package
1355 --help=recursive display the short help of all the included packages
1356 -V, --version display version information and exit
1357 -q, --quiet, --silent do not print \`checking ...' messages
1358 --cache-file=FILE cache test results in FILE [disabled]
1359 -C, --config-cache alias for \`--cache-file=config.cache'
1360 -n, --no-create do not create output files
1361 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1363 Installation directories:
1364 --prefix=PREFIX install architecture-independent files in PREFIX
1365 [$ac_default_prefix]
1366 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1367 [PREFIX]
1369 By default, \`make install' will install all the files in
1370 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1371 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1372 for instance \`--prefix=\$HOME'.
1374 For better control, use the options below.
1376 Fine tuning of the installation directories:
1377 --bindir=DIR user executables [EPREFIX/bin]
1378 --sbindir=DIR system admin executables [EPREFIX/sbin]
1379 --libexecdir=DIR program executables [EPREFIX/libexec]
1380 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1381 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

1384 --includedir=DIR C header files [PREFIX/include]
1385 --oldincludedir=DIR C header files for non-gcc [/usr/include]

1461 /usr/src/linux/include) [default=compiler default]
1462 --with-tls enable support for TLS
1463 --without-__thread do not use TLS features even when supporting them
1464 --with-cpu=CPU select code for CPU variant
1466 Some influential environment variables:
1467 CC C compiler command
1468 CFLAGS C compiler flags
1469 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1470 nonstandard directory <lib dir>
1471 LIBS libraries to pass to the linker, e.g. -l<library>
1472 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1473 you have headers in a nonstandard directory <include dir>
1474 CPP C preprocessor
1475 CXX C++ compiler command
1476 CXXFLAGS C++ compiler flags
1478 Use these variables to override the choices made by `configure' or to help
1479 it to find libraries and programs with nonstandard names/locations.
