Upon further RTFMing on start tokens, I tried this:
// Create and use an instance of the Python derived class
Base* py = python::extract<Base*>(
PyRun_String("PythonDerived()\n", Py_eval_input, 0, 0));
This gives an access violation in find_instance_impl which is called by
extract_pointer<Ptr>::extract_pointer(PyObject* obj) as far as I can
tell. And the Base& version wouldn't compile as I said.
What (else) am I doing wrong?
PS I forgot to mention that I'm using Intel C++ Compiler 6.0 on Windows
2000 SP2 with Boost 1.29.0.
