1580 Usage: $0 [OPTION]... [VAR=VALUE]...
1581
1582 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1583 VAR=VALUE.  See below for descriptions of some of the useful variables.
1584
1585 Defaults for the options are specified in brackets.
1586
1587 Configuration:
1588   -h, --help              display this help and exit
1589       --help=short        display options specific to this package
1590       --help=recursive    display the short help of all the included packages
1591   -V, --version           display version information and exit
1592   -q, --quiet, --silent   do not print \`checking ...' messages
1593       --cache-file=FILE   cache test results in FILE [disabled]
1594   -C, --config-cache      alias for \`--cache-file=config.cache'
1595   -n, --no-create         do not create output files
1596       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1597
1598 Installation directories:
1599   --prefix=PREFIX         install architecture-independent files in PREFIX
1600                           [$ac_default_prefix]
1601   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1602                           [PREFIX]
1603
1604 By default, \`make install' will install all the files in
1605 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1606 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1607 for instance \`--prefix=\$HOME'.

1848   CFLAGS      C compiler flags
1849   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1850               nonstandard directory <lib dir>
1851   LIBS        libraries to pass to the linker, e.g. -l<library>
1852   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1853               you have headers in a nonstandard directory <include dir>
1854   CXX         C++ compiler command
1855   CXXFLAGS    C++ compiler flags
1856   CXXCPP      C++ preprocessor
1857   CPP         C preprocessor
1858   GMPLIBS     How to link GMP
