Regression: Protoc fails on Linux ARM64 with the latest versions

[tverboon]

What version of gRPC and what language are you using?

2.76.0 and C#.

What operating system (Linux, Windows,...) and version?

Ubuntu 24.04 on ARM64 (Mac VM)

What runtime / compiler are you using (e.g. .NET Core SDK version dotnet --info)

.NET 10 on local GitHub Runner.

What did you do?

Building fails with protoc.

What did you expect to see?

A success, like on the Mac.

What did you see instead?

/media/psf/LinuxScratch/actions-runner/_work/_nuget/packages/grpc.tools/2.76.0/build/_protobuf/Google.Protobuf.Tools.targets(291,5): error MSB6006: "/media/psf/LinuxScratch/actions-runner/_work/_nuget/packages/grpc.tools/2.76.0/tools/linux_arm64/protoc" exited with code 139. 

Anything else we should know about your project / environment?

I think this is the root cause: grpc/grpc#38538, but this issue seems to be stale, hopefully this helps to move it forward. Currently I keep using version 2.67. Thanks.

Hi

The Grpc.Tools package is maintained in the grpc repo. It isn't something I have any experience with updating. I can ping some people in the gRPC team to see if that creates some progress, but I don't have capacity or capability to fix it myself.

Thanks, @JamesNK. This is exactly what I was hoping for.

@JamesNK, looking forward for any recommendation from you/grpc team how to solve the issue. IMO the best option is to update system used for the compilation (glibc dependency in fact).
