Error when installing with Homebrew MacOS 10.15.7

[callmecampos]

I get the following error when installing ARGoS with Homebrew on MacOS Catalina 10.15.7, following https://www.argos-sim.info/core.php. Any idea why I'm getting namespace errors with cmath?

> brew tap ilpincy/argos3
Error:
  homebrew-core is a shallow clone.
To `brew update`, first run:
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
This command may take a few minutes to run due to the large size of the repository.
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!

It seems to be an error in XCode: https://stackoverflow.com/questions/61236772/clang-doesnt-compile-cmath-in-macos-catalina

If you try and compile a basic program with cmath, does it work?

I have found this thread: https://forums.swift.org/t/is-anyone-else-getting-this-error-when-building-the-compiler-from-master-on-macos/36113/4. It seems to be a common problem, that affects many formulas beyond ARGoS.
