Hi, I am trying to do the following: SomeClassOfMine* myInstance; // Assume valid pointer boost::python::object myObject( myInstance ); However, doing so causes an exception to be thrown when I run my application. The exception thrown is below (Note I'm using MSVC9): First-chance exception at 0x7c812aeb in Crusades_Debug.exe: Microsoft C++ exception: boost::python::error_already_set at memory location 0x0012f0cc.. Unhandled exception at 0x7c812aeb in Crusades_Debug.exe: Microsoft C++ exception: boost::python::error_already_set at memory location 0x0012f0cc.. How can I assign the pointer above to a boost::python::object? I'm trying to give my python scripts access to an instance of a class that I haven't really exposed to Python yet, so I'm not sure of the consequences of that. I was going to extend the SomeClassOfMine class to python later on after I verify that I can get this working. Once I have myObject in a valid state, I will insert it into the __main__'s __dict__ namespace for a specific module so that it has access to it as a global python variable. Help is appreciated.
