1477 \`configure' configures this package to adapt to many kinds of systems.
1479 Usage: $0 [OPTION]... [VAR=VALUE]...
1481 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1482 VAR=VALUE. See below for descriptions of some of the useful variables.
1484 Defaults for the options are specified in brackets.
1487 -h, --help display this help and exit
1488 --help=short display options specific to this package
1489 --help=recursive display the short help of all the included packages
1490 -V, --version display version information and exit
1491 -q, --quiet, --silent do not print \`checking...' messages
1492 --cache-file=FILE cache test results in FILE [disabled]
1493 -C, --config-cache alias for \`--cache-file=config.cache'
1494 -n, --no-create do not create output files
1495 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1497 Installation directories:
1498 --prefix=PREFIX install architecture-independent files in PREFIX
1499 [$ac_default_prefix]
1500 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1503 By default, \`make install' will install all the files in
1504 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1505 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1506 for instance \`--prefix=\$HOME'.
1508 For better control, use the options below.

1667 Some influential environment variables:
1668 CC C compiler command
1669 CFLAGS C compiler flags
1670 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1671 nonstandard directory <lib dir>
1672 LIBS libraries to pass to the linker, e.g. -l<library>
1673 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1674 you have headers in a nonstandard directory <include dir>
1675 CXX C++ compiler command
1676 CXXFLAGS C++ compiler flags
