Official Linux ARM64 builds
This has been a long awaited feature: how to run Crystal on ARM64 CPUs?
Crystal has supported ARM64 as a tier 1 architecture for many years now, and we already distribute an universal build for macOS, but still no ARM64 builds for Linux.
The wait is over! During the development of Crystal 1.19 we bootstrapped a 1.18.2 compiler for ARM64 that was then used to bootstrap official builds for nightlies and the 1.19 release.
The builds are available everywhere we provide an AMD64 build of the compiler for Linux: nightly builds, release tarballs, Docker images, Snap, as well as the install-crystal GitHub action — just select an ubuntu arm runner.
