• https://github.com/pantsbuild/pants/pull/10927 says it included "along with a README.md explaining how to build and upload other versions" but uhh... I don't see a
README.mdh

10/29/2025, 7:25 PMThat was saying that the README.md was uploaded to the binaries.pantsbuild.org S3 bucket

10/29/2025, 7:25 PMAnd it's still there

10/29/2025, 7:26 PM Copy code
To add new versions of `grpc_python_plugin`, do the following on Linux and MacOS:
1. Build grpc from sources, using the cmake instructions at <https://github.com/grpc/grpc/blob/master/BUILDING.md>.
2. Upload the `grpc_python_plugin` file using
aws --profile=pants s3 cp --acl public-read \
./grpc_python_plugin \
<s3://binaries.pantsbuild.org/bin/grpc_python_plugin/$REV/$PLATFORM/x86_64/grpc_python_plugin>
Where `$REV` is the grpc version (e.g., `1.32.0`) and `$PLATFORM` is `linux` or `macos`.happy-kitchen-89482

10/29/2025, 7:35 PMI can take a stab at trying to build it, but
aws --profile=pantsh

10/29/2025, 8:07 PMah right
happy-kitchen-89482
10/29/2025, 8:07 PMif you're able to build it I can upload it

10/30/2025, 3:09 PMAfter looking at this more, I'm wondering if we should just point towards https://github.com/nhurden/protoc-gen-grpc-python-prebuilt
(or fork the repo to 'run'/host it out of our github org)
The cross-compiling instructions in https://github.com/grpc/grpc/ are very much an exercise for the reader
