My build is with xcode clang - not brew clang Satish On Thu, 9 Dec 2021, Mark Adams wrote:

Mpich seems to give the same error. I use clang 13.0. I think I get that from homebrew. Should I try something like: brew install llvm@12

I see:

llvm is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.

Believe me, I was sufficiently shocked when everything magically started working the 3rd time around :)

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. See discussions here:

Monterey. And my serial, optimized build works but it seems to use the same

compiler.

I am testing the parallel build again with debug turned off.
