1332 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1333
1334 Usage: $0 [OPTION]... [VAR=VALUE]...
1335
1336 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1337 VAR=VALUE. See below for descriptions of some of the useful variables.
1338
1339 Defaults for the options are specified in brackets.
1340
1341 Configuration:
1342 -h, --help display this help and exit
1343 --help=short display options specific to this package
1344 --help=recursive display the short help of all the included packages
1345 -V, --version display version information and exit
1346 -q, --quiet, --silent do not print \`checking ...' messages
1347 --cache-file=FILE cache test results in FILE [disabled]
1348 -C, --config-cache alias for \`--cache-file=config.cache'
1349 -n, --no-create do not create output files
1350 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1351
1352 Installation directories:
1353 --prefix=PREFIX install architecture-independent files in PREFIX
1354 [$ac_default_prefix]
1355 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1356 [PREFIX]
1357
1358 By default, \`make install' will install all the files in
1359 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1360 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1361 for instance \`--prefix=\$HOME'.
1362
1363 For better control, use the options below.
1364
1365 Fine tuning of the installation directories:
1366 --bindir=DIR user executables [EPREFIX/bin]
1367 --sbindir=DIR system admin executables [EPREFIX/sbin]

1462 Some influential environment variables:
1463 CC C compiler command
1464 CFLAGS C compiler flags
1465 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1466 nonstandard directory <lib dir>
1467 LIBS libraries to pass to the linker, e.g. -l<library>
1468 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1469 you have headers in a nonstandard directory <include dir>
1470 CPP C preprocessor
1471 CXX C++ compiler command
1472 CXXFLAGS C++ compiler flags
1473
1474 Use these variables to override the choices made by `configure' or to help
1475 it to find libraries and programs with nonstandard names/locations.
