Issues with Version 1.0.0 about toolchains_llvm

--cxxopt=-Xclang --cxxopt=-fno-cxx-modules can mitigate it but we need a fundamental solution.

@fmeum's fix in #337 should have resolved that issue - are you seeing it even with that patch applied? Appreciate it hasn't made it into a release yet, we're probably overdue cutting a new version.

I could not find an easy solution. So for the time being I have pinned my repos to a commit hash just before version 1.0.0.

I am facing the same issue. @helly25 Any workaround that you discovered?

I tried successfully #337 with https://github.com/helly25/mbo/releases/tag/0.2.27 but I have a private repository where it causes issues. I'll investigate that further.

[helly25]

The issue I now have with the private repo is that _system_module_map now uses ctx.actions.template_dict().join_all() with arg allow_closure = True. That requires Bazel version 7+ which I cannot use yet in that repo.

[helly25]

After applying the fix from #337 the mentioned private repository works fine after upgrading to Bazel 7.2.1.

It also works in v1.1.2 without patching.

@ahojnnes Feel free to reopen the bug if this still fails for you with an actual supported Bazel version.
