Hi, I have a question regarding the below code. It's an example how to pass a custom class via shared_ptr to embedded python code and it works when boost is dynamically linked. Unfortunately the same code with statically linked boost doesn't work with the following error message: "No to_python (by-value) converter found for C++ type: class boost::shared_ptr<class Foo>". I don't understand why a different linking can affect type recognition of a registered converter. What am I missing? Can anybody help me out?
