1482 Usage: $0 [OPTION]... [VAR=VALUE]...
1484 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1485 VAR=VALUE. See below for descriptions of some of the useful variables.
1487 Defaults for the options are specified in brackets.
1490 -h, --help display this help and exit
1491 --help=short display options specific to this package
1492 --help=recursive display the short help of all the included packages
1493 -V, --version display version information and exit
1494 -q, --quiet, --silent do not print \`checking...' messages
1495 --cache-file=FILE cache test results in FILE [disabled]
1496 -C, --config-cache alias for \`--cache-file=config.cache'
1497 -n, --no-create do not create output files
1498 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1500 Installation directories:
1501 --prefix=PREFIX install architecture-independent files in PREFIX
1502 [$ac_default_prefix]
1503 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1506 By default, \`make install' will install all the files in
1507 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1508 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1509 for instance \`--prefix=\$HOME'.
1511 For better control, use the options below.

1674 Some influential environment variables:
1675 CC C compiler command
1676 CFLAGS C compiler flags
1677 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1678 nonstandard directory <lib dir>
1679 LIBS libraries to pass to the linker, e.g. -l<library>
1680 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1681 you have headers in a nonstandard directory <include dir>
1682 CXX C++ compiler command
1683 CXXFLAGS C++ compiler flags
1685 CXXCPP C++ preprocessor
1686 GMPLIBS How to link GMP
1687 GMPINC How to find GMP include files
1688 PPLLIBS How to link PPL
