While compiling with g++/c++/clang/clang++ I always get:

I have already tried to reinstall gcc, Xcode and Xcode Command Line Tools. I've looked at Catalina C++: Using <cmath> headers yield error: no member named 'signbit' in the global namespace, but the answer there is based around the fact that I failed to setup Cmake when I'm using pure g++. Also, that answer redirected me to Cannot compile R packages with c++ code after updating to macOS Catalina, where best answer suggests to run xcode-select --install
, which I've already tried.
I've also tried to xcode-select -s /Library/Developer/CommandLineTools
, but it didn't help either.
