Configuration

Operating system: macOS Ventura 13.0.1

PlatformIO Version (platformio --version): PlatformIO Core, version 6.1.5

Description of problem

I installed platformio, but when I went to try to process/run/build a project, I got the following error:

Compiling .pio/build/STM32F1/FrameworkArduinoVariant/board.cpp.o
sh: /Users/[xxx]/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-g++: Bad CPU type in executable

Steps to Reproduce

1. Run on apple M1 hardware
2. Prep virtual environment: python3.10 -m venv p; . ./p/bin/activate
3. Install PlatformIO: pip install -U platformio
4. Checkout blueSCSI: git clone https://github.com/erichelgeson/BlueSCSI
5. Build it: cd BlueSCSI && platformio run

Actual Results

See above:

$ platformio run

Expected Results

I expected that native arm binaries for the built tools are installed, and that the build would be successful.

If problems with PlatformIO Build System:

Source and platformio.ini files are in the git repo cloned in the steps to reproduce.

Additional info

ARM does make official Apple arm64 built tools available: arm-gnu-toolchain-12.2.rel1-darwin-arm64-arm-none-eabi/bin/arm-none-eabi-gcc: Mach-O 64-bit executable arm64

from: https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads

Yes, I could install rosetta 2 to run the x86_64 binaries, but platformIO should install native binaries for the hardware I'm running when available instead of non-native ones. It is likely other people are not seeing this issue because they installed Rosetta 2 already.

[jmgurney]

I just did some additional poking around, and it looks like your compatibility testing is incorrect: https://registry.platformio.org/tools/platformio/toolchain-gccarmnoneeabi/compatibility?version=1.90301.200702

This lists that it should be compatible, but clearly installed the incorrect binaries, so likely the compatibility test system has rosetta 2 installed, meaning it cannot determine if packages are compatible with darwin_arm64.

I did just try the latest version, 1.100301.220327, and THAT does contain working darmin_arm64 binaries. It should refuse to install incompatible versions of the platform and issue a warning if they do not work. Yes, it complicated by the fact that rosetta 2 may not be installed, but a simple test could be run, and an error issued about the incompatibility.

It looks like you only use the latest version to test compatibility, as https://registry.platformio.org/tools/platformio/toolchain-gccarmnoneeabi/compatibility?version=1.70201.0, which was released before the first M1 macs publicly available lists macos arm64 compatibility and we've already established that 1.90301.200702 is not compatible.

There are tons of older binaries and toolchains which will likely not see recompilation for native Darwin ARM64 (think of: toolchain-atmelavr version 5.4.0), so I agree with the CEO there at the community topic that Rosetta is needed.

[jmgurney]

I'm fine w/ that answer, just the UX should be better in that an explicit notification that Rosetta 2 needs to be installed instead of Bad CPU type in executable. Even though I knew about this issue, I still spend a little bit of time figuring it out.
