cpp-tutorial can't find external linux toolchain #383

Open inmcm opened 11 months ago

inmcm commented 11 months ago

Trying to run the cpp-tutorial as written on amd64 Ubuntu 22.04, the compilation process cannot find the external toolchain.

$ cd stage1
$ bazelisk build //main:hello-world

WARNING: --enable_bzlmod is set, but no MODULE.bazel file was found at the workspace root. Bazel will create an empty MODULE.bazel file. Please consider migrating your external dependencies from WORKSPACE to MODULE.bazel. For more details, please refer to https://github.com/bazelbuild/bazel/issues/18958.

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.

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

irshadcc commented 9 months ago

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

https://github.com/bazelbuild/bazel/issues/19915

vangyzen commented 6 months ago

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.
