Anything else we should know about your project / environment?

[AustinSchuh]

rules_apple is way too old inside gRPC. Upgrading it causes other problems though.

[eugeneo]

Please verify the Bazel version you use.

Is there any plan to upgrade it so that user can build grpc with newer bazel version like 7.0.0?

@AustinSchuh

No clue, I'm a fellow bazel user who is also trying to upgrade to bazel 7 and is blocked by gRPC not supporting bazel 7 yet. I got this far in debugging, then it got hard enough that I don't want to maintain an out of tree patch to upgrade. I shared this to make it easier for someone to get started. (Last time I contributed a fix, it took 2 years to merge. I don't have enough time to do that here)

[eugeneo]

Bazel 7 is not yet supported by gRPC. We will work on support once the final version of Bazel 7 is released.

[AustinSchuh]

https://releases.bazel.build/7.0.0/release/index.html is now released, any update?

[eugeneo]

I believe some work have been done. Have anybody tried building gRPC with Bazel7 now?

[faximan]

We can successfully build grpc with Bazel 7.0.2 and bzlmod, using an old version though:

bazel_dep(name = "protobuf", version = "23.1", repo_name = "com_google_protobuf")
bazel_dep(name = "grpc", version = "1.56.3.bcr.1", repo_name = "com_github_grpc_grpc")

with --enable_bzlmod=false, we get the apple error above.

[gattytto]

hello I come to join the flock, I'm hitting this same error when trying to use bazel 7.1.1 I'm bulding a project based on googleapis/googleapis WORKSPACE file and only the target /:build_gen works, the rest will give either an apple error or a "this code was built with a different version of protobuf" error depending on the grpc version used in the WORKSPACE file

[apsaltis-ddog]

This might be closable now -- looks like the .bazelversion in the root of the repository has been saying 7+ since https://github.com/grpc/grpc/pull/36105 in March. Local builds for me got past the rules_apple error mentioned in the description here.

[harrisonfang-helm]

Just wanted to confirm that I was able to get this working with bazel 7.3.1, grpc 1.65.0, and protobuf 26.1
