Subject: Cross-compilation support - call for test / nix-help
Date: Thu, 30 Jun 2022 11:42:49 -0000	[thread overview]
Message-ID: <165658936959.1819.5219940816209777882@atuin.qyliss.net> (raw)

Hi all,

As Ivan (@jonne) updated earlier this week on #spectrum, we've got initial cross-compilation support for aarch64 available in Spectrum development fork. It still needs some TLC before Spectrum PRs but is a great step forward. Our current ref. board is NXP i.MX8 but rootfs build should be fairly easy to modify for RPi4 configs already in nixpkgs for anyone who cares to try.

Quick how-to for non-nixos host like Ubuntu:
git clone -b aarch64-imx8-crosscompile https://github.com/tiiuae/nixpkgs-spectrum.git
git clone -b aarch64-imx8-crosscompile https://github.com/tiiuae/spectrum.git
cd spectrum/host/rootfs
nix-build -I nixpkgs=../../../nixpkgs-spectrum

Know issue:
- crossSystem from https://github.com/tiiuae/spectrum/commit/aad5f90cf2ec931f2af5c8d5111a9fac11686f8b#diff-5e4605b8d5634dcdcce8f0963ac46b90dc052b9a6de153cbd8e625f105c9be9aR6 is ignored on NixOS host but not on Ubuntu - maybe someone can point us why.

Thanks, 

-Ville
