RTTI and Portability in C++

If a compiler doesn't "support" RTTI, does that mean that the compiler can not handle class hierarchies that have virtual functions in them? Or have I been misunderstanding the literature about how RTTI isn't portable, and the issues lie elsewhere?

Thank you all for your comments!

Solution

RTTI is not needed for virtual functions.

It is mainly used for dynamic_cast and typeid.
