Hi, I'm getting "unregistered void cast" exception while serialization. I've followed the header file order recommended for serialization. i.e. #include <boost/archive/binary_oarchive.hpp> #include <boost/archive/binary_iarchive.hpp> #include <boost/serialization/serialization.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/is_abstract.hpp> //only in files where class is ABC #include <boost/serialization/export.hpp> //Followed by other headers like utility, map, vector, string Do I need to do something else as well? I've few derived classes for which I don't have any data. I've tried exporting those as well. But I still get the error.
