[C++-sig] Wrapping a class with a private copy ctor

[Matthew Scouten]

Right, so the class that I need to wrap has a private copy ctor.  I do
not need to copy objects of this class, or pass them to and from
python.  I only need to subclass them in python. In fact I only ever
need one. But Boost::python seems to choke on the private copy ctor.
Is there a way around this?

example code:

class Base
{
	private:
	Base(const Base&);
	Base & operator=(const Base &);
}

class Derived : public Base
{

}

struct Derived_wrapper : Derived
{
}

BOOST_PYTHON_MODULE(core)
{
	class_<CTTPriceConsumer_wrapper>("CTTPriceConsumer");
}
