I am trying to run this on Win32, using Stackless Python 2.6, and Boost 1.47.
I am having a problem with passing a shared_ptr of a C++ object implementing a C++ interface to a wrapper of a Python object implementing a C++ interface. That's a mouthful, so I thought I'd simplify the code. The thing is, I can't seem to get the wrapping correct. If I can get this going, I can start adding complication to it and see what the problem really is. Basically, I have an interface that works with itself for communicating stuff. There is a C implementation of it, and a Python implementation of it. I have to write a wrapper. The Python implementation can communicate with instances of the C implementation, but not vice versa. When the C implementation calls the Python one, I get: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: No to_python (by-value) converter found for C++ type: class boost::shared_ptr<class Communicatable> The magic call is in the python script.

The shared_ptrs are part of the larger problem I'm trying to reproduce, so I want to incorporate them into this test program. In the larger program, while doing a get_override() call on a wrapper to an interface, I get a segfault inside the Python DLLs while it tries to convert the shared_ptr. The last line I can see i shared_ptr_to_python.hpp: return converter::registered<shared_ptr<T> const&>::converters.to_python(&x); That's what I am eventually hoping to reproduce by shooting back and forth all this stuff.
