1431 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1433 Usage: $0 [OPTION]... [VAR=VALUE]...
1435 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1436 VAR=VALUE. See below for descriptions of some of the useful variables.
1438 Defaults for the options are specified in brackets.
1441 -h, --help display this help and exit
1442 --help=short display options specific to this package
1443 --help=recursive display the short help of all the included packages
1444 -V, --version display version information and exit
1445 -q, --quiet, --silent do not print \`checking...' messages
1446 --cache-file=FILE cache test results in FILE [disabled]
1447 -C, --config-cache alias for \`--cache-file=config.cache'
1448 -n, --no-create do not create output files
1449 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1451 Installation directories:
1452 --prefix=PREFIX install architecture-independent files in PREFIX
1453 [$ac_default_prefix]
1454 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1457 By default, \`make install' will install all the files in
1458 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1459 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1460 for instance \`--prefix=\$HOME'.
1462 For better control, use the options below.

1589 Some influential environment variables:
1590 CC C compiler command
1591 CFLAGS C compiler flags
1592 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1593 nonstandard directory <lib dir>
1594 LIBS libraries to pass to the linker, e.g. -l<library>
1595 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1596 you have headers in a nonstandard directory <include dir>
1597 CXX C++ compiler command
1598 CXXFLAGS C++ compiler flags
1600 CXXCPP C++ preprocessor
1601 CXXFILT Location of GNU c++filt. Defaults to the first GNU version of
1602 `c++filt', `gc++filt' on PATH.
1604 Use these variables to override the choices made by `configure' or to help
1605 it to find libraries and programs with nonstandard names/locations.
