Philip,

if you have a lot of C/C++ code and look for wrappers, you could also try SWIG 

http://www.swig.org/Doc1.3/Ruby.html

or the rbplusplus gem 

http://rubyforge.org/projects/rbplusplus/

There have been rumours on this list some time ago that SWIG could also "wrap" Ruby into C, but I couldn't confirm this from the docs.

I think the rbplusplus gem is very comfortable, but it's still work in progress ... 0.1.1 doesn't seem
to support struct for instance, but the last build from git does...

What is it that's most time-consuming in your application ?

Best regards,

Axel
