1624 Usage: $0 [OPTION]... [VAR=VALUE]...
1625
1626 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1627 VAR=VALUE.  See below for descriptions of some of the useful variables.
1628
1629 Defaults for the options are specified in brackets.
1630
1631 Configuration:
1632   -h, --help              display this help and exit
1633       --help=short        display options specific to this package
1634       --help=recursive    display the short help of all the included packages
1635   -V, --version           display version information and exit
1636   -q, --quiet, --silent   do not print \`checking ...' messages
1637       --cache-file=FILE   cache test results in FILE [disabled]
1638   -C, --config-cache      alias for \`--cache-file=config.cache'
1639   -n, --no-create         do not create output files
1640       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1641
1642 Installation directories:
1643   --prefix=PREFIX         install architecture-independent files in PREFIX
1644                           [$ac_default_prefix]
1645   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1646                           [PREFIX]
1647
1648 By default, \`make install' will install all the files in
1649 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1650 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1651 for instance \`--prefix=\$HOME'.
1652
1653 For better control, use the options below.

1933   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1934               nonstandard directory <lib dir>
1935   LIBS        libraries to pass to the linker, e.g. -l<library>
1936   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1937               you have headers in a nonstandard directory <include dir>
1938   CXX         C++ compiler command
1939   CXXFLAGS    C++ compiler flags
1940   CXXCPP      C++ preprocessor
1941   CPP         C preprocessor
1942   GMPLIBS     How to link GMP
1943   GMPINC      How to find GMP include files
