1349 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1351 Usage: $0 [OPTION]... [VAR=VALUE]...
1353 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1354 VAR=VALUE. See below for descriptions of some of the useful variables.
1356 Defaults for the options are specified in brackets.
1359 -h, --help display this help and exit
1360 --help=short display options specific to this package
1361 --help=recursive display the short help of all the included packages
1362 -V, --version display version information and exit
1363 -q, --quiet, --silent do not print \`checking ...' messages
1364 --cache-file=FILE cache test results in FILE [disabled]
1365 -C, --config-cache alias for \`--cache-file=config.cache'
1366 -n, --no-create do not create output files
1367 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1369 Installation directories:
1370 --prefix=PREFIX install architecture-independent files in PREFIX
1371 [$ac_default_prefix]
1372 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1375 By default, \`make install' will install all the files in
1376 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1377 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1378 for instance \`--prefix=\$HOME'.
