Thanks for pointing this out, Stefan. When I ran Arch some years ago, I remember running into similar problems with a previous GCC update. I also seem to remember something about Arch and Python3? Anyway, most OSes move significantly slower than Arch does when it comes to updating compiler & interpreter versions. Obviously we will need to fix these
eventually, though, so it's good to know about them.
I think your suggestion of setting the C++ standard in CMake is a good one, and is probably something that we should be tracking more publicly. Thanks for making the suggestion!
Cheers,
Ben
