RTTI and portability in C ++

Question

If the compiler does not support RTTI, does this mean that the compiler cannot process class hierarchies that have virtual functions? Or did I misunderstand the literature that RTTI is not portable and the problems are somewhere else?

Thank you all for your comments!

Answer 1

For virtual functions, RTTI is not required.

Mostly used for dynamic_castand typeid.
