Question

Can anybody tell me how to activate RTTI in c++ when working on unix.
I heard that it can be disabled and enabled.
on my unix environment,how could i check whether RTTI is enabled or disabled?

I am using the aCC compiler on HPUX.

Answer 1

Are you using g++ or some other compiler?

In g++ RTTI is enabled by default IIRC, and you can disable it with -fno-rtti. To test whether it is active or not use dynamic_cast or typeid

UPDATE

I believe that HPUX’s aCC/aC++ also has RTTI on by default, and I am unaware of a way to disable it. Check your man pages.
