Using Boost Python & std::shared_ptr

Question

I\'m trying to get Boost Python to play nicely with std::shared_ptr. Currently, I\'m receiving this error:

Traceback (most recent call last):
  File \"test.py\",

A snippet from http://boost.2283326.n4.nabble.com/No-automatic-upcasting-with-std-shared-ptr-in-function-calls-td4573165.html:

/* make boost::python understand std::shared_ptr */
namespace boost {
       template
       T *get_pointer(std::shared_ptr p)
       {
               return p.get();
       }
}

Worked for me. You would define your classes like:

class_>("Foo", ...);

With this, other methods returning std::shared_ptr will Just Work.

Some magic may be required for virtual functions/polymorphism, that should be covered in the thread I linked to.
