Yahoooo! Finally, I got the thing to work. Here is how I did it.
/* import the module that holds the base class */
PyObject *base_module = PyImport_ImportModule("module_name");
if (!base_module) return;
/* get a pointer to the base class */
PyObject *base_class = PyMapping_GetItemString(
PyModule_GetDict(base_module,"BaseClass")
);
if (!base_class) return;
/* assign it as base class */
cclassType.tp_bases = Py_BuildValue("(O)",BaseClass);
I am doing all this before the call to PyType_Ready() -- as
Scoot Daniels suggested. Using the python API's SetAttrString()
did not work (I suppose for the same reason, why assigning
cls.__bases__ does not work in pure python either).
I also checked
cclassType.tp_base = (PyTypeObject *) base_class;
which also works and I am not aware of the difference of these two
slots.
Anyway, for my simple purposes it works just fine.
