1623 Usage: $0 [OPTION]... [VAR=VALUE]...
1624
1625 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1626 VAR=VALUE.  See below for descriptions of some of the useful variables.
1627
1628 Defaults for the options are specified in brackets.
1629
1630 Configuration:
1631   -h, --help              display this help and exit
1632       --help=short        display options specific to this package
1633       --help=recursive    display the short help of all the included packages
1634   -V, --version           display version information and exit
1635   -q, --quiet, --silent   do not print \`checking ...' messages
1636       --cache-file=FILE   cache test results in FILE [disabled]
1637   -C, --config-cache      alias for \`--cache-file=config.cache'
1638   -n, --no-create         do not create output files
1639       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1640
1641 Installation directories:
1642   --prefix=PREFIX         install architecture-independent files in PREFIX
1643                           [$ac_default_prefix]
1644   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1645                           [PREFIX]
1646
1647 By default, \`make install' will install all the files in
1648 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1649 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1650 for instance \`--prefix=\$HOME'.
1651
1652 For better control, use the options below.

1932   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1933               nonstandard directory <lib dir>
1934   LIBS        libraries to pass to the linker, e.g. -l<library>
1935   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1936               you have headers in a nonstandard directory <include dir>
1937   CXX         C++ compiler command
1938   CXXFLAGS    C++ compiler flags
1939   CXXCPP      C++ preprocessor
1940   CPP         C preprocessor
1941   GMPLIBS     How to link GMP
1942   GMPINC      How to find GMP include files
