[C++-sig] Advice sought on making a large C++ application a Python extension

Hi Ben

Thanks very much for your reply. Sorry that my response has been slow but I have been trying to digest yours. I have also taken a detour to investigate CMake.

I'm sorry to say that I don't really understand the concept of making the Python portion only an interface to the underlying C++ code. Please could you explain what that means? 

Best regards
