Hi, Sorry to bother you like this every few hours but I've found another bug with Pyste (previous version) when generating code for overloaded virtual functions. Here is a test program. // ---------- overload.hpp ---------- namespace test { class Base { public: virtual void f(const int i) = 0; }; class A : public Base{ public: void f(const int i) {} void f(const double d, const int i) {} }; } // -------------------- When compiling the file that Pyste generates for this, it produces this error message: overload.cpp: In function `void init_module_overload()': overload.cpp:59: no matching function for call to `boost::python::class_<test::A,{anonymous}::test_A_Wrapper,boost::python::detail::not_specified,boost::python::detail::not_specified>::def (const char[2], {unknown type}, void ({anonymous}::test_A_Wrapper::*)(int))' The generated code segment for the function looks like this: .def("f", &test::A::f, &test_A_Wrapper::default_f) .def("f", (void (test::A::*)(const double, const int) )&test::A::f) The fix is to replace it like so: .def("f", (void (test::A::*)(const int) ) &test::A::f, &test_A_Wrapper::default_f) .def("f", (void (test::A::*)(const double, const int) )&test::A::f) Only the first line is changed. I've also attached a patch to ClassExporter.py that fixes this for me. Oh! I just spent an hour and a half debugging this but it looks like this was fixed in the latest version that has the _name bug. FWIW, I've attached the patch anyway but this patch is for the ClassExporter.py version 1.29. cheers, prabhu
