You need to either build your own C wrapper around the C++ and expose that
in Ruby as you cannot just map C++ objects to Ruby's C-API.

Or you use a tool like Rice ( http://rice.rubyforge.org ) or SWIG to wrap
the C++ into Ruby.

I would also recommend looking into Rb++ ( http://rbplusplus.rubyforge.org )
which IMO (though slightly biased) is easier to deal with than SWIG.
