[C++-sig] Wrapping pointers

[Dominic Sacré]

Hi,

I'm having trouble exporting C++ pointers to Python. My code looks like 
this:

class A
{
    A *p;
    ...
};

BOOST_PYTHON_MODULE(test)
{
    class_<A>("A", init<>())
        .def_readonly("p", &A::p)
        ...
    ;
}

Now every time I try to access A::p from Python I get this error:

TypeError: No to_python (by-value) converter found for C++ type: A*

I searched the list archives and found a message about the same issue, 
where the only suggestion was to use

.def_readonly("p", make_getter(&A::p, return_internal_reference<1>()))

instead, but this doesn't help either. On the contrary, this causes a 
segfault every time I use A::p (although p points to a valid object, at 
least in C++).
So what should I do to access this pointer from Python?

Thanks,
