Ensuring RTTI is on for QtCreator

gjscnc

I am developing a Qt 5 desktop application (Linux) where one component in the architecture requires RTTI for release. When executing this code via QtCreator I get a RTTI run-time error.

I've been having difficulty debugging, so I'm investigating to see if something may be occurring with Qt.

Are the release versions of the Qt libraries and QtCreator compiled with RTTI turned off or on by default?
If RTTI is off by default, what is the best way to turn RTTI on and recompile (for example, CONFIG += RTTI?)?

I've been running in circles on this and would greatly appreciate the benefit of someone else's experience.

Thanks in advance.

Regards,

George
