Mmmkay, looks like I found a dirty little workaround: I put the C++ functions, I want to expose into a dummy class: class Dummy { int f1(str arg1, ... void f2(tuple arg1, ... } And then create a bpy object from it: object tmp = class_("dummy") .def("f1", &Dummy::f1)

Hi everyone, I'm just starting to check out pybindgen after the messages I've seen floating around on this mailing list, and I have a question about the pygccxml integration. I've made a pure-virtual class with a pointer return type, like so: class pure_virtual_class { virtual int get_val
