Docker cross-platform Elixir build for linux/amd64 on linux/arm64, Apple Silicon M1, M2, M3, etc.

Problem

When building an Elixir application docker image on an arm64 platform, the process crashes with a variety of errors:

• Segmentation fault
• Error code 139
• Error code 143
• Memory request of some enormous size

Virtualized Ubuntu Studio on Arm64

Ubuntu Studio only offers amd64 downloads. These can run in a VM in emulation mode which is slow. The sequence to install an equivalent system in arm64 is the following:

1. Install Ubuntu Server LTS (currently 22.04.4).
2. Update apt:

sudo apt update && sudo apt upgrade

Disable:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

Enable:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

Prerequisites

1. DCamProf source (1.0.6 is the latest)
2. Clang compiler with openmp support
3. little-cms2
4. libtiff

Under macOS with XCode installed typically the compiler picked up is the one shipped with XCode. It does not support openmp:

Run RawTherapee custom linux build on Windows 10 with sharp fonts on a HiDPI display

Note that this setup may be a moot point as there are important issues when running RT under WSL. One is the overall low performance compared to a Linux in a Virtual Box setup. Another is repeatable freezes of the VM when the contents of the directory currently open in RT are modified on the host. For these and other reasons the Virtual Box setup turned out to be superior to the WSL.

The credit for WSL setup for graphical apps belongs to https://medium.com/@jeffborch/running-the-scenic-elixir-gui-framework-on-windows-10-using-wsl-f9c01fd276f6.
