Re: gnat link to c++ classes (all gcc)

["Steve" <nospam_steved94@attbi.com>]

Have you tried the GNAT User's Guide?

In Gnat 3.15p the section is:
  2.11.2 Linking a Mixed C++ & Ada Program
And:
  2.11.3 A Simple Example

I have dynamically linked C++ to Ada with a non-gnat compiler, but I've have
done it the hard way.  I create an instance of a tagged type corresponding
to each class, and keep a copy of the "this" pointer for the class in the
tagged type.  On the "C++" side I have extern C functions that are called
from the Ada side and cast the "this" pointer to the appropriate type to
invoke the method.

If anyone wants I could put together a small example.
