Cannot build cpp-tutorial on Apple M1

[markub3327]

Description of the problem / feature request:

Cannot build a cpp examples on Apple M1. I used bazel installed by Homebrew.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

brew install --verbose bazel
git clone https://github.com/bazelbuild/examples
bazel build //main:hello-world

What operating system are you running Bazel on?

macOS Big Sur, Apple M1

What's the output of bazel info release?

release 4.1.0-homebrew

If bazel info release returns "development version" or "(@non-git)", tell us how you built Bazel.

brew install --verbose bazel

What's the output of git remote get-url origin ; git rev-parse master ; git rev-parse HEAD ?

https://github.com/bazelbuild/examples

master
fatal: ambiguous argument 'master': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git [...] -- [...]'

Have you found anything relevant by searching the web?

No. I tried to find about it on Google.

Any other information, logs, or outputs that you want to share?

Before running bazel build //main:hello-world I tried export BAZEL_USE_CPP_ONLY_TOOLCHAIN=1 and it's working. But I don't know is it a suitable solution. On the other projects it's not working!!!!

Do you have Xcode installed fully? Or just the command line tools? If it's the latter this is fixed in 4.2.0 which should be released soon. You can try it with one of the latest release candidate builds to verify https://releases.bazel.build/4.2.0/rc3/index.html

I cannot repro this on my M1 machine with a full Xcode installation so I assume this is a duplicate of #13514

[markub3327]

Yes I have only Xcode CLI installed. Fully installed Xcode is not needed with bazel 4.2.0rc3 !!!

Great, sounds like we can close this then?

Yes, all is working. Thanks a lot.
