Thank you. This works:

{
class_ a("A",init<>());
class_, boost::noncopyable >("B",init<>());
}

As this error message suggests: as B derives from A, it is (by default)
non-copyable, too. That you have to tell python, too, thus:

He is right. The following code was generated by Py++:
#include "boost/python.hpp"
namespace bp = boost::python;

Hello,
I am still in the early process of learning boost.python.
I have reduced my problem to the following code:
#include
using namespace boost::python;
class A{
private:
A(const A&){}; //no public copy constructor
};
class B: public A{
public:
B(){};
};

Sorry, the public A::A() constructor was missing. The corrected class A, which
caused the described problem, is:
class A{
private:
A(const A&){}; //no public copy constructor
public:
A(){};
};
