1509 \`configure' configures package-unused version-unused to adapt to many kinds of systems.

1511 Usage: $0 [OPTION]... [VAR=VALUE]...
1512
1513 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1514 VAR=VALUE. See below for descriptions of some of the useful variables.
1515
1516 Defaults for the options are specified in brackets.
1517
1518 Configuration:
1519 -h, --help display this help and exit
1520 --help=short display options specific to this package
1521 --help=recursive display the short help of all the included packages
1522 -V, --version display version information and exit
1523 -q, --quiet, --silent do not print \`checking ...' messages
1524 --cache-file=FILE cache test results in FILE [disabled]
1525 -C, --config-cache alias for \`--cache-file=config.cache'
1526 -n, --no-create do not create output files
1527 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1528
1529 Installation directories:
1530 --prefix=PREFIX install architecture-independent files in PREFIX
1531 [$ac_default_prefix]
1532 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1533 [PREFIX]
1534
1535 By default, \`make install' will install all the files in
1536 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1537 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1538 for instance \`--prefix=\$HOME'.
1539
1540 For better control, use the options below.

1690 Some influential environment variables:
1691 CC C compiler command
1692 CFLAGS C compiler flags
1693 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1694 nonstandard directory <lib dir>
1695 LIBS libraries to pass to the linker, e.g. -l<library>
1696 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1697 you have headers in a nonstandard directory <include dir>
1698 CXX C++ compiler command
1699 CXXFLAGS C++ compiler flags
1700 CPP C preprocessor
1701 CXXCPP C++ preprocessor
1702 CXXFILT Location of GNU c++filt. Defaults to the first GNU version of
1703 `c++filt', `gc++filt' on PATH.
1704
1705 Use these variables to override the choices made by `configure' or to help
1706 it to find libraries and programs with nonstandard names/locations.
