The term Canadian Cross was coined because at the time that these issues were all being hashed out, Canada had three national political parties (per Wikipedia).

Reposting here:
I am working on readding support for relibc and redoxos to nixpkgs. That requires adding support for the relibc library which is a replacement for libc compatible with redox.
https://github.com/NixOS/nixpkgs/pull/453786

But I run into an infinite recusion problem when I try nix-shell -A pkgsCross.x86_64-unknown-redox.mkShell.

       … while evaluating the attribute 'stdenv.cc.targetPrefix'

It is a circular dependency which should be solvable.

How do I best solve this?

How could that be fixed?

either patching the makefiles to find the correct CC, or exporting some environment variable shenanigans.
I suspect this may be an issue too: https://github.com/NixOS/nixpkgs/blob/6a08e6bb4e46ff7fcbb53d409b253f6bad8a28ce/pkgs/by-name/li/libparserutils/package.nix#L21
Build system should probably be in native inputs.

Build system should probably be in native inputs, not sure.

Ok so good news. After spending way to much time on this I got dillo to compile and x11 to run. The issue is my mouse does not work in x11 and ideally I would like to use the labwc compositor under wayland, that I also got to run. The mouse works there so that is good. However the one thing I could not get running in the chain is xwayland.
