1426 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1428 Usage: $0 [OPTION]... [VAR=VALUE]...
1430 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1431 VAR=VALUE. See below for descriptions of some of the useful variables.
1433 Defaults for the options are specified in brackets.
1436 -h, --help display this help and exit
1437 --help=short display options specific to this package
1438 --help=recursive display the short help of all the included packages
1439 -V, --version display version information and exit
1440 -q, --quiet, --silent do not print \`checking...' messages
1441 --cache-file=FILE cache test results in FILE [disabled]
1442 -C, --config-cache alias for \`--cache-file=config.cache'
1443 -n, --no-create do not create output files
1444 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1446 Installation directories:
1447 --prefix=PREFIX install architecture-independent files in PREFIX
1448 [$ac_default_prefix]
1449 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1452 By default, \`make install' will install all the files in
1453 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1454 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1455 for instance \`--prefix=\$HOME'.
1457 For better control, use the options below.

1578 Some influential environment variables:
1579 CC C compiler command
1580 CFLAGS C compiler flags
1581 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1582 nonstandard directory <lib dir>
1583 LIBS libraries to pass to the linker, e.g. -l<library>
1584 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1585 you have headers in a nonstandard directory <include dir>
1586 CXX C++ compiler command
1587 CXXFLAGS C++ compiler flags
1589 CXXCPP C++ preprocessor
1590 CXXFILT Location of GNU c++filt. Defaults to the first GNU version of
1591 `c++filt', `gc++filt' on PATH.
1593 Use these variables to override the choices made by `configure' or to help
1594 it to find libraries and programs with nonstandard names/locations.
