zmitchell | Hey everyone, I've started working on RedoxOS support again after it seems like it has been dormant for a while | 22:06:44 |
zmitchell | Just wanted to say hi to all the other crazy people trying to support Nix on "exotic" targets lol | 22:07:24 |
zmitchell | aaronjanse: it looks like you were the last person to make progress on this, thanks for your work! | 22:08:08 |

zmitchell | Alright I have a patch for RedoxOS support, and I've added it to the list of patches for gcc here: https://github.com/NixOS/nixpkgs/compare/master...zmitchell:nixpkgs:zmitchell/redox-gcc-support
I'm not quite sure how to verify that I'm building it properly because I would expect to have to rebuild gcc from source, but a nix-build -A gcc or nix-build -A gcc13 in my nixpkgs fork takes about 2s and seems to substitute gcc rather than build it.

zmitchell | Trying to build the cross-compiler doesn't evaluate either:
$ nix-build -A pkgsCross.x86_64-unknown-redox.gcc13

Alyssa Ross | That's not a cross compiler | 11:47:54 |
Alyssa Ross | That's a cross compiled native compiler | 11:47:59 |
Alyssa Ross | A cross compiler would be pkgsCross.x86_64-unknown-redox.stdenv.cc or pkgsCross.x86_64-unknown-redox.buildPackages.gcc13

zmitchell | Ah, it looks like relibc was recently removed from nixpkgs due to lack of maintenance. It also looks like Redox has their own patched Rust compiler.
I'm sifting through the nixpkgs source right now to try to figure out where I would swap out the URL pointing at rustc sources, but I'm a little confused by the layout. In pkgs/build-support/rust I see a bootstrap.nix that calls binary.nix , and that seems to download compiler binaries. But also in pkgs/development/compilers/rust it looks like rustc.nix is where we actually build rustc , but it takes a rustc argument?
| 19:07:59 |

Alyssa Ross | Yes, it uses the bootstrap rustc to build itself | 08:20:01 |
Alyssa Ross | I'd first try to see how far you can get using the non-patched Rust compiler, which does have Redox targets | 08:20:19 |
Alyssa Ross | I'd be hesitant to add a patched rustc to Nixpkgs, because the last one made maintaining normal rustc more difficult. | 08:20:39 |
zmitchell | I wouldn't be adding the patched rustc to nixpkgs exactly for that reason. It also seems like their patched rustc exists because there's something missing from the upstream compiler. I'm not up to speed on that particular issue. | 15:16:35 |
zmitchell | My plan at the moment is get the patched rustc/cargo/etc packaged in their respective repositories, then replace the upstream versions via overlay in order to build relibc. That artifact can be exposed to nixpkgs. | 15:18:07 |
