Hi, My experience with Boost.Python and Pyste have so far been superb. Thanks for the wonderful library and tool! I think I've just found a bug with Pyste regarding handling virtual operators. Virtual functions seem to be OK but operators cause trouble. Consider the following minimal test code: // ------- file.hpp ------------- namespace test { class Op { public: virtual ~Op() {} virtual Op& operator ++ () = 0; }; } // -------------------- I now wrap this using something like so in a Pyste file. op = AllFromHeader('file.hpp') When generating file.cpp everything is fine but when compiling the file errors are generated since the wrapper code does not generate wrappers for the operator and this cannot be instantiated. In the above case there is no wrapper code generated at all. The problem also persists with concrete virtual member operators -- since the wrappers are not generated. The code compiles but there would be problems since one would not be able to overload it in a derived class in Python. I guess this is a bug? Thanks! cheers, prabhu
