 Mic92 | nix-community.cachix.org will than also cache some core-components for cross compiling NixOS from x86 to riscv64. | 13:29:20 |

nix-community.cachix.org will than also cache some core-components for cross compiling NixOS from x86 to riscv64. What about cross compiling from aarch64 to riscv64? | 04:20:53 |
 cnx | why x86 and aarch64 when amd64 chips with good single thread perf are much more common? | 09:34:12 |

why x86 and aarch64 when amd64 chips with good single thread perf are much more common? I'm pretty sure amd64 is what Mic was referring to when they said "x86". | 10:48:28 |
| Alex | It's quite a common way of referring to the whole family of x86_64 ISAs. | 10:49:39 |

We are just one pull request away from having our first image for nixos-anywhere: https://github.com/NixOS/nixpkgs/pull/321991 just tried building an iso from an x86 machine and was reminded of https://github.com/NixOS/nixpkgs/issues/231537 | 13:19:29 |
| Pratham Patel (you can mention me) | any idea on the blockers on this? maybe I could help? | 13:19:44 |
| Pratham Patel (you can mention me) | on rev: 4c547b66635455ad061d4beecaf1805810dc0428 | 13:20:24 |
| Mic92 | Pratham Patel (you can mention me): do you have any VM or hardware that has a kernel with kexec enabled? | 13:20:29 |
| Pratham Patel (you can mention me) | I'm on an x86 machine, the VF2 is "away" for the time being | 13:20:58 |
| Mic92 | We don't build isos in this pull request yet. | 13:21:02 |

I'm on an x86 machine, the VF2 is "away" for the time being Ok. I have x86. I can potentially spin up some scaleway riscv64 machine. | 13:21:39 |
| Pratham Patel (you can mention me) | I realize that. What I'm asking is if you had a list of blockers for bootstrapping riscv64 GHC on x86 | 13:21:40 |
| Mic92 | Not sure when I get to it. | 13:21:43 |
| Alex | If you're not building any Haskell packages on purpose, you should try disabling ShellCheck (by default, it is used to check all shell scripts). | 13:21:46 |
| Mic92 | In reply to @thefossguy:matrix.org
I realize that. What I'm asking is if you had a list of blockers for bootstrapping riscv64 GHC on x86 Ah. There it's basically ghc not publishing bootstrap binaries afaik. | 13:22:10 |
| Mic92 | Yes. Disabling shellcheck is the way to go. | 13:22:31 |
| Alex | In reply to @thefossguy:matrix.org
I realize that. What I'm asking is if you had a list of blockers for bootstrapping riscv64 GHC on x86 Nixpkgs generally relies on upstream bindists, but there are a few (as-of-yet unmerged?) PRs to also make it possible to bootstrap via cross. | 13:22:33 |
| Mic92 | Can we not also upload our own cross-compiled ghc binary tarball? | 13:23:19 |
| Mic92 | to tarballs.nixos.org? | 13:23:24 |
| Pratham Patel (you can mention me) | I'm not sure. Only now starting to understand Nix after being 1+ years in the Nix ecosystem lol | 13:23:57 |
| Pratham Patel (you can mention me) | Okay, my custom minimal ISO started building :) | 13:24:25 |
| Alex | In reply to @joerg:thalheim.io
Can we not also upload our own cross-compiled ghc binary tarball? That is definitely worth discussing with the Nixpkgs maintainers, but it'd be easier once the changes that enable cross-compilation of GHC are merged.
The PRs that enable it also add x86_64 -> riscv64 cross-compilation to Hydra to catch regressions. | 13:24:49 |
| Alex | So once the changes are merged, the Hydra build could be downloaded and packaged into a tarball to bootstrap native builds (or, more likely, used to package a complete native build). | 13:26:05 |
| Mic92 | Also sounds good to me. | 13:26:24 |
| Alex | The newest PR for this is: https://github.com/NixOS/nixpkgs/pull/305392
(It works already, but I think sterni might want to make a few changes before it is merged?) | 13:27:50 |
