Hello everyone,

I've got a C++ object that I've created a Python type for. When I insert the object into the main module using PyModule_AddObject then I can instantiate it in Python and everything works just fine. I assumed (mostly from reading other's code) that I could use something

Hi Stefan, Yes.... I originally got a copy of this code (and the recommendation to move to the CVS version) from you via this list. When I last left boost, using your example code, the library was crashing on: bpl::object main = python::import("__main__"); as I was trying to add my instance to the main module's dictionary. Because of that I've abandoned boost for the time being and am trying to simply understand the C API better. I suppose I could look into the boost::python code to see what operator[] is doing but I was hoping a quick answer from the mailing list would point me in the right direction, with either the correct API function or telling me what I'm missing.

Up to this point there is no need to use the C API directly. Assuming you have exported your C++ type 'Type' to python, you can write (inside C++): namespace bpl = boost::python; bpl::object instance(Type(...)); bpl::dict global; global["instance"] = instance; bpl::exec_file(python_script, global, global); and the executed script can access your Type instance directly through the 'instance' variable. Caution: the 'exec_file' function has been added after 1.33.1, so you need to use a CVS snapshot.
