Problem with RTTI

What is wrong with this code

Code:

---

Obj<TCHAR>* obj = dynamic_cast<Obj<TCHAR>* >(I->objects[0]);

---

Which is resulting in this error

Code:

---

A dynamic cast is present, but the correct RTTI option is not specified.

---

Maybe you have to specify some copiler option to let it generate extra code to enable the dynamic_cast keyword to work?
At least, it is what IBM compiler requires: http://publib.boulder.ibm.com/infoce...2Fruoptrtt.htm

What are those compiler options that I have to specify?

How could I know it?
