Subject: Re: Q: FFI and C++?

Because of the complexity that C++ adds, I doubt that any feasible FFI
library can be made that works reliably against C++ libraries, though
Charles will probably be a better voice for whether this is truely
possible or not.

For now, there are a few libraries now out that will definitely help
you out (and are IMO a ton better than trying to deal with SWIG, but
I'm slightly biased). They are:

Rice - A C++ development library that abstracts out the internals of
Ruby's object model to make wrapping C++ libraries as easy as
possible.
  http://rice.rubyforge.org/
  http://github.com/cout/rice

Rb++ - Using GCCXML and Rice to auto-generate wrappers of the C++ code
you are wanting to wrap
