This module wraps all of the 'mpq' (rational) functions that
the Gnu MP (GMP) library provides. It requires gmp-4.2.0 or later.

You therefore need the GMP library installed on your computer. See:
https://gmplib.org/

To build this module you need perl 5.6.0 or later. I'm not sure of all
the requirements to get it to build with earlier versions of perl, but
it's definite that the XS code relating to operator overloading will
not compile with perl versions prior to 5.6.

No OO interface - just plain access to GMP's rational number functions.

Build in the usual way:

 perl Makefile.PL
 make
 make test
 make install

When building this module, the GMP library will need to be accessible.
If it's in a location where your compiler does not find 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"

==============
64-bit support
==============

If your perl's Config reports that 'ivsize' is greater than or
equal to 8 && 'ivtype' is not 'long', then Math::GMPq will, by
default, be built to enable you to use the 64-bit long long int
values with the new() function and the overloaded operators.


Similarly, if your perl's Config reports that 'nvsize' > 8,
then Math::GMPq will, by default, be built to enable you to use the
larger precision values (be they either 'long double' or '__float128'
with the new() function and the overloaded operators.

I am contactable by email at sisyphus at(@) cpan dot (.) org.

MAC OS X
==========

If you have MacPorts installed, you may need to install gmp +universal
for the bindings to work. After installing you'll need to run:

perl Makefile.PL INC="-I/opt/local/include" LIBS="-L/opt/local/lib -lgmp"

MS WINDOWS
==========
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"
