@ArbitCode
I got this the other day. It is a Clang setting you need to make IIRC. In other words, your code is good, but the Clang being used in Creator needs something adjusted, but I can't quite recall what....

EDIT Ah it was this you need to act on: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=952718

I think the resolution is I installed: sudo apt-get install libclang-common-8-dev

Hey @JonB
Thank you so much, I did not expect that I get a reply so early.

It's resolved the problem.
