Ok so I was here minding my own business making a new class, and I go to build and I get an error in locale_classes.h. I've never seen anything like this, and not sure what it's problem is.
Strange!
I found a few bits on google on this, but no real solutions.
One thing that worked for smeone was to put a semicolon after the closing brace of the class }; - worth checking out, otherwise one of the many experts on here will need to help you out.
