1343 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.

1345 Usage: $0 [OPTION]... [VAR=VALUE]...
1346
1347 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1348 VAR=VALUE. See below for descriptions of some of the useful variables.
1349
1350 Defaults for the options are specified in brackets.
1351
1352 Configuration:
1353 -h, --help display this help and exit
1354 --help=short display options specific to this package
1355 --help=recursive display the short help of all the included packages
1356 -V, --version display version information and exit
1357 -q, --quiet, --silent do not print \`checking ...' messages
1358 --cache-file=FILE cache test results in FILE [disabled]
1359 -C, --config-cache alias for \`--cache-file=config.cache'
1360 -n, --no-create do not create output files
1361 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1362
1363 Installation directories:
1364 --prefix=PREFIX install architecture-independent files in PREFIX
1365 [$ac_default_prefix]
1366 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1367 [PREFIX]
1368
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'.
1373
1374 For better control, use the options below.

1476 Some influential environment variables:

1479 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1480 nonstandard directory <lib dir>
1481 LIBS libraries to pass to the linker, e.g. -l<library>
1482 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1483 you have headers in a nonstandard directory <include dir>
1484 CPP C preprocessor
1485 CXX C++ compiler command
1486 CXXFLAGS C++ compiler flags
1487
1488 Use these variables to override the choices made by `configure' or to help
1489 it to find libraries and programs with nonstandard names/locations.
