ubuntu 18.04 is out for aarch64 on the raspberry pi, and that’s awesome, but I need my crystal on it. Crystal is perfect for these tiny machines, and so it’d be awesome if I could build my apps.
I’ve been following instructions from here: https://translate.google.com/translate?hl=en&sl=ru&tl=en&u=http%3A%2F%2Fconstxife.ru%2Fblog%2F2018%2F10%2F16%2Frpi-crystal.html (The original blog post is in russian). I’ve gotten it mostly built, except for one problem: https://github.com/crystal-lang/crystal/issues/5556#issuecomment-469404469

I think that means there’s a bug in LLVM that I don’t have the fix for in ubuntu 18.04 llvm (1:6.0-41~exp5~ubuntu1). Has anyone else encountered this problem, or have a solution for it? I’ve also asked in ubuntu-specific land, but I’m not allowed to put more than 2 links in a post.
Thanks!
