Describe the problem

Seems the binary for g++ is wrong.

Errore:

Compilation error: fork/exec /Users/antonio/Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-g++: bad CPU type in executable

To reproduce

  1. Clean Macbook.
  2. Install Arduino IDE 2.3.3
  3. Attach Arduino Due to USB.
  4. Board is recognized, load Blink example.
  5. The IDE ask correctly to install the toolchain for the board, arduino:sam
  6. ToolChain Installed.
  7. Compile Blink.

Expected behavior

Working.

Arduino IDE version

2.3.3

Operating system

macOS

Operating system version

Sequoia 15.0.1

Hi @antoniocaruso. The "arm-none-eabi-gcc" compiler toolchain used to compile sketches for the Arduino Due board is only distributed in builds for "Intel" (x86) CPUs. This is not a significant problem for those of us with macOS machines that have Apple Silicon CPUs because Apple provides the Rosetta 2 binary translator that allows binaries built for x86 host architectures to run on Apple Silicon CPUs.

The reason why you encountered this error is because you don't have Rosetta 2 installed. macOS is smart enough to notify you that you need to install Rosetta 2 when you start an application that requires it. Unfortunately it is not smart enough to do that when Arduino IDE invokes an x86 executable (as it does when you compile for the Arduino Due).

So the solution will be for you to install Rosetta 2. You can do that by following the instructions here:

Yes solved but a native toolchain would be useful.
