Looks like CI is failing with:

ERROR: error loading package '@com_github_google_benchmark//tools': Unable to find package for @py_deps//:requirements.bzl: The repository '@py_deps' could not be resolved.

I probably won't be able to take a closer look until end of week earliest, but @silvergasp do you have any idea what might cause that error?

[nathaniel-brough]

No stress. This one is just an autogenerated version bump. But it doesn't seem to have worked it out properly. So feel free to have a go at sorting it out.

Definitely low priority though, this is just a dev dependency, and it's only used in the CI to test that the toolchain works against a set of 'common' repositories, but it's certainly not critical.

[akirabaruah]

Took a quick peek at the error and it seems like github.com/google/benchmark added some new deps to its WORKSPACE file between v1.5.0 and v1.5.6.

The offending dep is a missing @py_deps Bazel repository included in the upstream WORKSPACE here. IIUC, the deps in that workspace aren't loaded by our downstream repo.

@silvergasp does this make sense? If so, what's the recommended way to resolve this issue?

A few possible solutions off the top of my head:

1. Load the required dep(s) from upstream directly in our WORKSPACE file.
2. Make a PR to the upstream repo to add a macro that loads all deps and call that in our WORKSPACE file.

[akirabaruah]

BTW @silvergasp I've downloaded this repo locally to an Ubuntu container and tried running the test command to try to reproduce the issue, but I'm running into this error:

$ bazelisk test @com_google_googletest//... @com_github_google_benchmark//... @com_google_absl//... --test_tag_filters=-benchmark
...
external/clang_llvm_12_00_x86_64_linux_gnu_ubuntu_16_04/bin/clang: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

Installing libtinfo-dev and rerunning seems to produce the same issue. Any ideas what I might be missing here?

[nathaniel-brough]

Yeah you'll need to install libncurses it's a runtime dep for clang. Otherwise that makes sense.
