Thanks for your response. You'll also need to move
#include "csound.h"  out of the extern "C" block
in csound.hpp

I have already done that. In fact, I removed extern "C" from csound.hpp,
as both files included (of which only csound.h needs to be included, by
the way) already have that where necessary. In csound.h, I moved the
extern "C" after the includes.
