Given a failed attempt (and a failed attempt at asking the right question: https://forum.nim-lang.org/t/7631), here I am again.
So... Let's ask the question in a more naive way: how do I go about compiling a Nim project for arm/arm64?
(Any Linux or macOS version will do - what I want to know is what configuration works for you, and what tools have to be pre-installed in order for that configuration to work)
That's what I thought too - but suddenly I end up with one million missing headers.
For examples, I'm using GMP. When I compile normally, every goes fine. When I switch to arm, suddenly the very same gmp.h (that is of course there) "cannot be found".
So, I've been wondering if I'm doing something completely wrong.
