This was a proof of concept and an attempt to get that working on GitHub Actions.
Since then I took a different approach, which I covered in my videos:
- Building CLIs with Crystal - Quick cross-compilation - Part 1
- Building CLIs with Crystal - Quick cross-compilation - Part 2
And the repository that collects all the static libraries for Linux (Alpine) and macOS is here: GitHub - luislavena/magic-haversack: Facilitate Crystal cross-compilation
Cheers.
