//local-remote-execution/generated/config:platform excludes darwin toolchains for non-remote execution builds

[adam-singer]

Description

//local-remote-execution/generated/config:platform seems to pollute or exclude building locally with bazel on MacOS. The defaults provide do not include darwin toolchains. This is problematic for building locally without using remote execution for builds.

bazel query //local-remote-execution/generated/config:platform --output build
# /Users/adam/workspace/native-link/local-remote-execution/generated/config/BUILD:35:9
platform(
  name = "platform",
  exec_properties = {"container-image": "docker://nativelink-toolchain:lslbs7cb2pdf0lgp14vz6kj9r2xbby55", "OSFamily": "Linux"},
  constraint_values = ["@platforms//os:linux", "@platforms//cpu:x86_64", "@bazel_tools//tools/cpp:clang"],
  parents = ["@local_config_platform//:host"],
)
# Rule platform instantiated at (most recent call last):
#   /Users/adam/workspace/native-link/local-remote-execution/generated/config/BUILD:35:9 in <toplevel>

Reproduce

On MacOS run (https://gist.github.com/adam-singer/46277e3f61aeaf6a6326520f03dfeb5c#file-gistfile0-txt-L247 )

bazel test -s  //nativelink-store/...

Same thing is happening on Windows. Working on a fix.

Ran into something similar as well

bazel test //... \

Looking into how to fix this now

@bclark8923 atm using bazel directly on this repo for build/test on mac is a work in progress. Using cargo for now is the best option on mac cargo test --all
