Re: [Boost-users] [serialization] "unregistered void cast" error --what does it mean?

Can anyone possibly clarify the cases when it is necessary to use "void_cast_register" with Boost::Serialization?

void_cast_register is invoked to register the relationship between a base class and derived class. Usually its automatic when a derived class serializes its base. When this doesn't occur, it has to be done explicitly. This is described in the manual. Robert Ramey
