cpp-tutorial can't find external linux toolchain

[sjwo]

Seems potentially related to recent thread in the Bazel getstarted slack: https://bazelbuild.slack.com/archives/CD42R4HJL/p1702485704389129. If it's the same issue, then you could try using Bazel 6.4, or specifying the --noincompatible_sandbox_hermetic_tmp build option with 7.0.0; both of these were successful workarounds for me.

Can this option be made default or can this be mentioned in the cpp tutorial https://bazel.build/start/cpp

bazelbuild/bazel#19915

I got the same problem,I dig somehow,find it seems the external/gcc_toolchain_x86_64/bin/gcc script parse the EXECROOT not correct,it goes to /tmp,but it seems you need to take bazel-working-directory/_main as your EXECROOT
the dir/libs all you need is all here
I am new to use bazel, not sure

This issue is a significant impediment to new users trying to use the cpp-tutorial to learn bazel. That workflow is completely broken on Ubuntu 20.04 and openSUSE Leap 15.5. I spent two full days finding this issue, mostly because I assumed I was doing something wrong.
