I should probably add, in CsoundVST, CsoundVST itself is not statically linked with the Csound API. CsoundVST loads Python, Python loads the Csound API and the CppSound class which inherits from the Csound API class, and then CsoundVST retrieves a global CppSound instance pointer from the Python object and calls functions off its virtual function table. Therefore, runtime polymorphism must be supported.

I presume that either the Python wrapper worked for you after you made this change, or you did not test the Python wrapper after you made this change. 

If it did work for you, I would like to know more about that. I wonder if virtual function tables are required for this to work on Windows, but not on Linux.

In any event, support for runtime polymorphism is important and must not be removed.

Regards,
Mike

Why was this removed ? It is only enabled for the *_wrap.cc files.
