So I had similar issues back when I originally wrote the clang linter — on Big Sur. The TL;DR for me was that Catalina originally shipped with broken cmath headers, something future updates wouldn’t necessarily fix. The only way to fix it was to:
1. Reinstall CLT 2. Reinstall/install Xcode 3. Repeat the above until it was fixed Now you may have an unrelated issue, but my error messages (e.g. about missing “signbit”, “std::less_than”, etc in global namespace) were very very similar.
