[C++-sig] this used to work?

[Nikolay Mladenov]

Hi,

This code used to work before (1_29_0), but now(boost-consulting:cvs
from yesterday) it does not:


//////////////////////////////////////////
class OBJ{
public :
    virtual int f()=0;
};

#include <boost/python.hpp>

using namespace boost::python;

BOOST_PYTHON_MODULE(obj)
{
        class_<OBJ, boost::noncopyable>("OBJ", no_init );
}
////////////////////////////////////////////



MSVC 6.5 complains
