1373 'configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1374
1375 Usage: $0 [OPTION]... [VAR=VALUE]...
1376
1377 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1378 VAR=VALUE.  See below for descriptions of some of the useful variables.
1379
1380 Defaults for the options are specified in brackets.
1381
1382 Configuration:
1383   -h, --help              display this help and exit
1384       --help=short        display options specific to this package
1385       --help=recursive    display the short help of all the included packages
1386   -V, --version           display version information and exit
1387   -q, --quiet, --silent   do not print 'checking ...' messages
1388       --cache-file=FILE   cache test results in FILE [disabled]
1389   -C, --config-cache      alias for '--cache-file=config.cache'
1390   -n, --no-create         do not create output files
1391       --srcdir=DIR        find the sources in DIR [configure dir or '..']
1392
1393 Installation directories:
1394   --prefix=PREFIX         install architecture-independent files in PREFIX
1395                           [$ac_default_prefix]
1396   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1397                           [PREFIX]
1398
1399 By default, 'make install' will install all the files in
1400 '$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
1401 an installation prefix other than '$ac_default_prefix' using '--prefix',
1402 for instance '--prefix=\$HOME'.
1403
1404 For better control, use the options below.
1405
1406 Fine tuning of the installation directories:
1407   --bindir=DIR            user executables [EPREFIX/bin]
1408   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1522   LIBS        libraries to pass to the linker, e.g. -l<library>
1523   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1524               you have headers in a nonstandard directory <include dir>
1525   CPP         C preprocessor
1526   CXX         C++ compiler command
1527   CXXFLAGS    C++ compiler flags
1528
1529 Use these variables to override the choices made by 'configure' or to help
1530 it to find libraries and programs with nonstandard names/locations.
