I was able to solve it by linking protoc again.

brew link protobuf make clean make BUILD_TYPE=metal build

[NinjAiBot]

make BUILD_TYPE=metal build

Thanks mate. The original issue was solved by relinking protobuf but then it failed at another point for me after following the steps in #1197

Still not managed a successful install though as I described in detail here

Always ends up like this:

[Aisuko]

Is it succeed to build? It is ok we get the Warning while the building process.

No.
I've never managed to get the build to get past this point. It always just seems to stop at this point and never progress.

Built with make and saw he same error OP saw which I worked around by:

BUILD_GRPC_FOR_BACKEND_LLAMA=on make backend/cpp/llama/grpc-server

And then rerunning the build target to complete compilation on an M2 chip running Fedora Asahi Remix.

@NinjAiBot my output looks just like yours, and it's working for me—I just followed the next steps in Example: Build on mac to download ggml-gpt4all-j.bin and ask it how it was. Try it! Thanks @renzo4web for the brew link protobuf step which fixed the build for me.

Just used LM-Studio instead. Was the easiest way to spin up a server to chat to a model which is what I needed to do
