Cannot use dynamic_cast with -fno-rtti

anonymous_user_1fe1a2a7 · February 10, 2015, 6:41pm

So, I’ve been struggling with following error for more than a week: it is forbidden to use dynamic_cast with non-unreal objects.

I’ve read, probably, all the topics I could find, but nothing helps( popular suggestion - bUseRTTI = true, but this fails to compile ).

I would be walking on air if somebody had helped me out, and I could finally get to work.

Running on mac, UE 4.6.1.

Hi vivalavladislav,

Sorry for the delay in responding to your post. Is this still an issue for you? I tried to reproduce this using the screenshot that you provided (setting the bUseRTTI variable to true), but did not see the error you showed when building the project. If you still need help with this, is there any additional information that you could provide?
