1427 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1429 Usage: $0 [OPTION]... [VAR=VALUE]...
1431 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1432 VAR=VALUE. See below for descriptions of some of the useful variables.
1434 Defaults for the options are specified in brackets.
1437 -h, --help display this help and exit
1438 --help=short display options specific to this package
1439 --help=recursive display the short help of all the included packages
1440 -V, --version display version information and exit
1441 -q, --quiet, --silent do not print \`checking...' messages
1442 --cache-file=FILE cache test results in FILE [disabled]
1443 -C, --config-cache alias for \`--cache-file=config.cache'
1444 -n, --no-create do not create output files
1445 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1447 Installation directories:
1448 --prefix=PREFIX install architecture-independent files in PREFIX
1449 [$ac_default_prefix]
1450 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1453 By default, \`make install' will install all the files in
1454 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1455 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1456 for instance \`--prefix=\$HOME'.
1458 For better control, use the options below.

1580 Some influential environment variables:
1581 CC C compiler command
1582 CFLAGS C compiler flags
1583 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1584 nonstandard directory <lib dir>
1585 LIBS libraries to pass to the linker, e.g. -l<library>
1586 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1587 you have headers in a nonstandard directory <include dir>
1588 CXX C++ compiler command
1589 CXXFLAGS C++ compiler flags
1591 CXXCPP C++ preprocessor
1592 CXXFILT Location of GNU c++filt. Defaults to the first GNU version of
1593 `c++filt', `gc++filt' on PATH.
1595 Use these variables to override the choices made by `configure' or to help
1596 it to find libraries and programs with nonstandard names/locations.
