[Roger Harman <roger.harman@xxxxxxxxxxx>]

That's an interesting statement.  If it's an ILE program (or module), why would it be difficult to call? 

I've only done a couple of C (not C++) programs on IBM i so I can't claim any expertise - just curiosity.

That's an option..

Except I want to call the C++ code from RPG...

And while it appears that can be done, it doesn't appear
