Hi, this issue can be solved by building with bazel5.

https://github.com/arch4edu/cactus/actions/runs/5133068703/jobs/9236993635

But new error shows:

I think it can be solved by adjusting the build flag or building with gcc12 or gcc11.

ray-project/ray#35200

Building with gcc12 solve the issue. Also added git and libxcrypt-compat to makedepends.

Closing this issue as @carlosal1015 is now maintaining this package. Thanks for all the bug reporting and tracking @petronny. When I get back to RL stuff again, I'll be sure to keep this in mind.

@carlosal1015 please address these comments when you get the chance.

Thanks, I will take a look today about conflict mesa demos and and look the dependencies.
