[error] (Protobuf / protobufGenerate) error occurred while compiling protobuf files: Unsupported platform: protoc-3.5.1-osx-aarch_64.exe

What is the expected behavior?

No error when sbt comiple

Steps to Reproduce

clone the project and run sbt compile

Your environment

• firrtl Verions: master branch
• OS: masOS Monterey

Any quick fixes or hacks for now to bypass this?

[ekiwi]

@jackkoenig Can we just remove the protobuf support?

[jackkoenig]

Protobuf is removed from firrtl brought in tree to Chisel and this repo is shifted to bug fixes only. Fixes this so we can build this repo going forward may make sense, but supporting ARMv8 MacOS is not a priority for that. That being said, we could potentially fix it by not using https://github.com/os72/protoc-jar any more (we are on the latest version) and instead requiring the user who is building firrtl to install protoc themselves.

[jackkoenig]

os72/protoc-jar is also Apache 2.0 licensed so we could also just in tree and fix the logic for ARM Macs
