Re: [Boost-users] [serialization] Assertion `new_cid==cid'failed-fails on gcc, works on msvc

OK

Try the following:

//BOOST_CLASS_EXPORT(base);

BOOST_CLASS_EXPORT(derived);

#include <boost/serialization/shared_ptr.hpp>

//BOOST_SERIALIZATION_SHARED_PTR(base);

BOOST_SERIALIZATION_SHARED_PTR(derived);

The base class shouldn't need exporting as it never

directly instantiated.
