1376 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1377
1378 Usage: $0 [OPTION]... [VAR=VALUE]...
1379
1380 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1381 VAR=VALUE.  See below for descriptions of some of the useful variables.
1382
1383 Defaults for the options are specified in brackets.
1384
1385 Configuration:
1386   -h, --help              display this help and exit
1387       --help=short        display options specific to this package
1388       --help=recursive    display the short help of all the included packages
1389   -V, --version           display version information and exit
1390   -q, --quiet, --silent   do not print \`checking ...' messages
1391       --cache-file=FILE   cache test results in FILE [disabled]
1392   -C, --config-cache      alias for \`--cache-file=config.cache'
1393   -n, --no-create         do not create output files
1394       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1395
1396 Installation directories:
1397   --prefix=PREFIX         install architecture-independent files in PREFIX
1398                           [$ac_default_prefix]
1399   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1400                           [PREFIX]
1401
1402 By default, \`make install' will install all the files in
1403 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1404 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1405 for instance \`--prefix=\$HOME'.
1406
1407 For better control, use the options below.

1514 Some influential environment variables:
1515   CC          C compiler command
1516   CFLAGS      C compiler flags
1517   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1518               nonstandard directory <lib dir>
1519   LIBS        libraries to pass to the linker, e.g. -l<library>
1520   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1521               you have headers in a nonstandard directory <include dir>
1522   CPP         C preprocessor
1523   CXX         C++ compiler command
1524   CXXFLAGS    C++ compiler flags
1525
1526 Use these variables to override the choices made by `configure' or to help
1527 it to find libraries and programs with nonstandard names/locations.
