This only happens with brew system and I think it is about building fat binaries for both arm and x86. I will try to disable arm support from the brew file for now.

dvtkrlbs commented 3 years ago

This is really strange I can manually build abseil as a fat library using make abseil-cpp-20200225 but the same thing does not work on brew build step.

yeah, this is due to brew's (IMO insane) shims they use to silently mess with clang invocations. let's merge this with https://github.com/michaeleisel/homebrew-zld/issues/4 . also, please try brew upgrade again
