[pygccxml-development] Exposing boost::python::list

[Scott S. <sc...@bi...>]

Hi,

I'd like to have a class which as a boost::python::list as a public 
attribute.  I know that gccxml cannot parse boost/python.hpp, so given a 
suggestion on the mailing list archives, I have done the following:

#pragma once
#ifndef __GCCXML__
#include <boost/python.hpp>
typedef boost::python::list list;
#else
class list;
#endif

class MyClass {
   public:
     list * mylist;
};

MyClass::MyClass()
{
   mylist = new boost::python::list();
   mylist.append(1);
}
MyClass::~MyClass()
{
   delete mylist;
}

Py++ is able to create the bindings and it compiles fine.  However, when 
accessing the 'mylist' attribute in python, I'm seeing the following 
behavior:

>>> print type(myclass.mylist)

>>> print type(myclass.mylist)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
TypeError: cannot create weak reference to 'list' object
>>> print type(myclass.mylist)
Fatal Python error: GC object already tracked
Aborted

I think I'm going about this the wrong way, but am unsure of the proper 
way.  Would this be a use case for the 'inserting_code' functionality of 
py++?

Thank you!

Scott
