C++: Can virtual inheritance be detected at compile time?

Question

I would like to determine at compile time if a pointer to Derived can be cast from a pointer to Base without dynamic_cast<>. Is this possible using templates and metaprogramm

Answer 1

I had the same problem, once. Unfortunately, I'm not quite sure about the virtual-problem. But: Boost has a class named is_base_of (see here) which would enable you to do smth. like the following

BOOST_STATIC_ASSERT((boost::is_base_of::value));

Furthermore, there's a class is_virtual_base_of in Boost's type_traits, maybe that's what you're looking for.
