Hi Roman
The problem is that: How export this class?
namespace geometry{
class point_t
{
public:
point_t() {};
protected:
virtual bool ret_bool() { return false; }
};
class point_2 : public point_t
{
public:
point_2() {};
};
}
I put attached the Py++ genereted code and a small test.
My question is, how export this protected virtual function? the way
used in Py++ not work in this case.
Thanks
