Fails to build on aarch64

dleslie commented 3 years ago

This will effect Raspberry Pi, Pinebook, and Apple M1 users.

I attempted both make and docker build -t gendev . and receive the same result.

Results in:

I attempted to replace all of the config.guess and config.sub files with the newest versions from GNU and it gets a bit farther, but results in:

I'm having the same issue here as @dleslie

It might be worth trying a newer gcc and matching binutils version, see if that works. Unfortunately, I have no easy way to directly build an arm and I don't see any arm runners on circleci.

I've been looking a bit into using an aarch64 cross compiled gcc to see if I could just create a package for arm, this should be possible, but isn't super quick and easy.

But yeah, you ought to be able to build this toolchain on ARM, but very likely need to update things to get that setup.

@gustavolinux @kubilus1 I went through the effort of fixing up Marsdev and getting its Dockerfile into an operational state; with binfmt and qemu-static it's been completely usable on aarch64.

dleslie commented 3 years ago

Probably worth doing the same with gendev - package it all up in a dockerfile and run it over qemu.

kubilus1 commented 3 years ago

Yeah, a qemu build may be what I end up going with. This is a problem for a lot of projects, that CICD tools like Circle haven't quite caught up to.

kubilus1 commented 3 years ago

I've updated GCC and deps, this should build on arm64 now.
