1583 Usage: $0 [OPTION]... [VAR=VALUE]...
1584
1585 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1586 VAR=VALUE.  See below for descriptions of some of the useful variables.
1587
1588 Defaults for the options are specified in brackets.
1589
1590 Configuration:
1591   -h, --help              display this help and exit
1592       --help=short        display options specific to this package
1593       --help=recursive    display the short help of all the included packages
1594   -V, --version           display version information and exit
1595   -q, --quiet, --silent   do not print \`checking ...' messages
1596       --cache-file=FILE   cache test results in FILE [disabled]
1597   -C, --config-cache      alias for \`--cache-file=config.cache'
1598   -n, --no-create         do not create output files
1599       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1600
1601 Installation directories:
1602   --prefix=PREFIX         install architecture-independent files in PREFIX
1603                           [$ac_default_prefix]
1604   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1605                           [PREFIX]
1606
1607 By default, \`make install' will install all the files in
1608 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1609 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1610 for instance \`--prefix=\$HOME'.

1855   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1856               nonstandard directory <lib dir>
1857   LIBS        libraries to pass to the linker, e.g. -l<library>
1858   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1859               you have headers in a nonstandard directory <include dir>
1860   CXX         C++ compiler command
1861   CXXFLAGS    C++ compiler flags
1862   CXXCPP      C++ preprocessor
1863   CPP         C preprocessor
1864   GMPLIBS     How to link GMP
