1344 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.

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

1479 Some influential environment variables:
1480 CC C compiler command
1481 CFLAGS C compiler flags
1482 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1483 nonstandard directory <lib dir>
1484 LIBS libraries to pass to the linker, e.g. -l<library>
1485 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1486 you have headers in a nonstandard directory <include dir>
1487 CPP C preprocessor
1488 CXX C++ compiler command
1489 CXXFLAGS C++ compiler flags
1490
1491 Use these variables to override the choices made by `configure' or to help
1492 it to find libraries and programs with nonstandard names/locations.
