Re: [Boost-users] boost serialization not working unless you have at least one virtual function in base

Does anybody know why this is the case?

Is there a way to make a class "polymorphic" without adding a dummy virtual function?

No there isn't.

Is this some "silly" optimization done by C++ compilers? Not generating vtables?

The compiler only generates a vtable for polymorphic types. In Christ, Steven Watanabe
