arduino-cli board list throws bad CPU type in executable on a M2 Mac without rosetta emulation installed

[aleroot]

Describe the problem

I have an M2 MacBookPro and I have installed arduino-cli_0.29.0_macOS_ARM64, when I try to list the board I get 2 : bad CPU type in executable ...

I don't want to install rosetta, so is there a way to have all the underlying tools compiled for ARM64?

What is the sense of having arduino-cli ARM64 if then uses underlying tools that are not ARM64 ?

To reproduce

install arduino-cli ARM64 on an Apple silicon Mac that doesn't have installed Rosetta, then run ./arduino-cli board list

Expected behavior

Everything should work without giving errors: bad CPU type in executable

Arduino CLI version

arduino-cli Version: 0.29.0 Commit: 76251df Date: 2022-11-17T09:21:37Z

Operating system

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the nightly build
• My report contains all necessary details

What is the sense of having arduino-cli ARM64 if then uses underlying tools that are not ARM64 ?

Unfortunately, there are a lot of tools to support in order to allow operation like the compile.
But I'm in favour of at least provide mdns-discovery and serial-discovery, so that basic operations would work, like listing the boards

Since native Apple Silicon builds of Arduino CLI are already produced, and Arduino CLI's tool installation system will already install the native Apple Silicon builds of tools when those are available (falling back to installing x86 when they are not), I'll close this as off topic.

We are now tracking the requests for Apple Silicon builds of serial-discovery and mdns-discovery in their own repositories:

• Add macos amd64 architecture serial-discovery#55
• Add macos amd64 architecture mdns-discovery#40
