Configuration

Operating system:

• macOS Sonoma 14.2.1
• Darwin Kernel Version 23.2.0: Wed Nov 15 21:54:51 PST 2023; root:xnu-10002.61.3~2/RELEASE_ARM64_T6030
• Apple M3 Pro

PlatformIO Version (platformio --version):

• PlatformIO Core, version 6.1.13

Description of problem

When running pio check with clangtidy on an Apple M3 Pro, the following error is returned:

OSError: [Errno 86] Bad CPU type in executable: '/Users/jonathanfoster/.platformio/packages/tool-clangtidy/clang-tidy'

It appears the incorrect architecture is choosen when installing tool-clangtidy.

$ arch
arm64
$ lipo -info /Users/jonathanfoster/.platformio/packages/tool-clangtidy/clang-tidy
Non-fat file: /Users/jonathanfoster/.platformio/packages/tool-clangtidy/clang-tidy is architecture: x86_64

Uninstalling and reinstalling tool-clandtidy produces the same error.

Steps to Reproduce

1. Configure platformio.ini to use clang-tidy.

   check_tool = clangtidy

2. Run static code analysis.

   pio check

Actual Results

$ pio check
Checking lilygo-t-display-s3 > clangtidy (board: lilygo-t-display-s3; platform: espressif32; framework: arduino)

============================================================

Expected Results

pio check should run without error.

Looks like the issue is with the tool-clangtidy registry config, the files for darwin_amd46 appear to be misconfigured. darwin_arm64 should be a different download URL than darwin_x86_64.

"files": [
  {
    "name": "tool-clangtidy-darwin_x86_64-1.150005.0.tar.gz",

    },

There is no native binary for Mac ARM.

Do you have Rosetta installed?

[jonathanfoster]

@ivankravets It looks like LLVM does have native binaries for Mac ARM now.

I can install Rosetta or even copy an arm64 binary from LLVM's repo as a work around, but it would be a better experience if this was supported in the registry. Any idea what's required to update the package config and provide an arm64 download URL?

[ivankravets]

I agree with you. There is another problem. 95% of all toolchains are NOT native ARM. You will still need Rosetta.

[jonathanfoster]

In my case, I'm using the espressif toolchain and clang-tidy is the only tool that isn't native ARM. Would it make sense to update packages incrementally as arm64 is supported?

What's required to update the tool-clangtidy package config and provide an arm64 download URL? Is there anywhere I can make the change and submit a PR? I'm happy to help however I can.
