Mixing Ada and C++ is not trivial, and certainly you should not expect
it to work without interacting with the Ada vendor to determine how it
should be done. Both Ada and C++ need to own the world (to deal with
initialization and finalization), and this may well cause difficulties.
In general I would expect it to be difficult unless the Ada vendor has
specifically taken steps to make it work (or the C++ vendor :-)

I assume you are wrapping the C++ stuff in C, since obviously it won't work
to call it directly unless the Ada compiler knows a lot about the C++ 
compiler including its name crunching algorithm.

GNAT interfaces quite smoothly with C++, but this did not happen accidentally,
it took quite a bit of design, technical work, and fiddling!
