Including exprtk requires compiler setting /GR
ExprTk is a lexer, parser and evaluator for equations. I've included it in my project and get two compiler errors.
First one is regarding the macro
The second one is the problem: C4541 in
Is it a problem activating /GR for Unreal Engine? If no, how can I activate it within an Unreal project?
Or even better, can I avoid that Casts.h is used with exprtk?
Unfortunately not. I skipped using exprtk with UE4 atm. In my case I had only a dozen equations so it was ok to hardcode each formula into an own class and doing some string manipulation for certain conditions myself. It is ugly but still ok if you only have a handful of possible equations and conditions.
