Thanks! I could try and make a complete repro available somehow, but let me know if you get to any problems yourself!

Thank you! OK, one thing at a time. The following use of a generated proto as a dependency of an on-disk proto causes an error for me: ``` load("@rules_proto_grpc//cpp:defs.bzl", "cpp_proto_library")...

Another issue with dependencies on generated protos arises when using the Python bindings. Extend the above as follows: ``` python_proto_library( name = "p5_consume_python_proto", protos = [":p5_consume_proto"], ) python_proto_library( name =...

I wonder if these issues also affected the external-repo case I had, so maybe let's concentrate on these two first, and then revisit the external repos afterwards.

Have you considered the `macos` branch? https://github.com/deepmind/lab/tree/macos It addresses some of those issues.

Ah, I see, sorry! Is 10.15 available on Travis?

What are the actual errors with my replacement `realpath`?

I'd like to understand why the `realpath` behaviour has changed on 10.15. Just to be sure, could you try out whether it has to do with the extension that allows...

Wonderful, thanks! That's a very trivial fix then :-) I'll get that committed.
