To build this module you need the GMP library installed on your computer. See: http://gmplib.org/
You will also need either Math::GMPz or Math::GMP
Build in the usual way:
perl Makefile.PL make make test make install
If the GMP library is not in a location where your compiler finds it by default, then instead of running 'perl Makefile.PL', you'll need to run:
perl Makefile.pl INC="-I/path/to/gmp_include" LIBS="-L/path/to/gmp_lib -lgmp"
Any problems, I am contactable by email at sisyphus at(@) cpan dot (.) org.
If building with an MSVC++ compiler against a MinGW-built gmp lib, you'll need to additionally link to MinGW's libgcc.a and libcoldname.a. First, create copies of the 3 '.a' files (named libgmp.lib, libgcc.lib, and libcoldname.lib) and then run:
perl Makefile.pl INC="-IC:/path/to/gmp_include" LIBS="-LC:/path/to/gcc_lib -lgcc -LC:/path/to/coldname_lib -lcoldname -LC:/path/to/gmp_lib -lgmp"
