1560 \`configure' configures this package to adapt to many kinds of systems.

1562 Usage: $0 [OPTION]... [VAR=VALUE]...
1563
1564 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1565 VAR=VALUE.  See below for descriptions of some of the useful variables.
1566
1567 Defaults for the options are specified in brackets.
1568
1569 Configuration:
1570   -h, --help              display this help and exit
1571       --help=short        display options specific to this package
1572       --help=recursive    display the short help of all the included packages
1573   -V, --version           display version information and exit
1574   -q, --quiet, --silent   do not print \`checking ...' messages
1575       --cache-file=FILE   cache test results in FILE [disabled]
1576   -C, --config-cache      alias for \`--cache-file=config.cache'
1577   -n, --no-create         do not create output files
1578       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1579
1580 Installation directories:
1581   --prefix=PREFIX         install architecture-independent files in PREFIX
1582                           [$ac_default_prefix]
1583   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1584                           [PREFIX]
1585
1586 By default, \`make install' will install all the files in
1587 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1588 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1589 for instance \`--prefix=\$HOME'.

1804 Some influential environment variables:
1805   CC          C compiler command
1806   CFLAGS      C compiler flags
1807   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1808               nonstandard directory <lib dir>
1809   LIBS        libraries to pass to the linker, e.g. -l<library>
1810   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1811               you have headers in a nonstandard directory <include dir>
1812   CXX         C++ compiler command
1813   CXXFLAGS    C++ compiler flags
1814   CXXCPP      C++ preprocessor
1815   CPP         C preprocessor
1816   GMPLIBS     How to link GMP
