 Leon | * It appears that the riscv32-embedded crossSystem's gcc is built with a hard-float libgcc by default, which seems a little weird to me. We don't set anything in that system definition explicitly, but setting something like gcc = { arch = "rv32i"; abi = "ilp32"; }; is sufficient to convince it to build a soft-float libgcc. | 11:13:59 |

 j-k | Just building a fresh sd image for visionfive, I'm guessing for the ZFS broken warning just NIXPKGS_ALLOW_BROKEN=1? | 13:11:24 |

Just building a fresh sd image for visionfive, I'm guessing for the ZFS broken warning just NIXPKGS_ALLOW_BROKEN=1? It's likely to genuinely not work. Are you using linuxPackages_latest? | 18:30:40 |
| Linux Hackerman | There's an attr in zfs called latestSupportedLinuxPackages or something, try setting boot.kernelPackages to that. If that's too old to support the hardware, I think you'll have to do without zfs for now | 18:32:01 |
| j-k | I'm just building https://github.com/zhaofengli/nixos-riscv64/blob/master/pkgs/default.nix#L24 | 18:32:46 |
| j-k | it mentions zfs here but IDK if it's actually used at all in the sd card image

 Zhaofeng Li | Yeah, I'm passing NIXPKGS_ALLOW_BROKEN=1. ZFS is pulled in by the installation image profile and was marked broken for 5.16 back then. | 18:37:06 |
| Zhaofeng Li | But I don't recommend building my branch right now, probably try https://github.com/NixOS/nixpkgs/pull/168826 | 18:38:47 |
| Zhaofeng Li | * But I don't recommend building my branch right now, probably try https://github.com/NixOS/nixpkgs/pull/168826 to be more up-to-date | 18:39:05 |
| j-k | well I'm a couple hours into building so maybe I'll just hang in there 😅 Do you recommend binfmt or crosscompile?
Also I manually tweaked the config to have ssh and my public key so I'm hoping I can just ssh in headless first try 🤞we'll see | 20:49:47 |

| Zhaofeng Li | For my branch I always did native and it may not even cross-compile, and my cache only contains native builds. | 00:33:55 |

 qbit | boot.binfmt.emulatedSystems have riscv64-linux in it? | 13:08:20 |
| j-k | yep. I've been trying to test it's set up properly on that remote machine, looks like it is

 Alyssa Ross | Ericson2314: I'm looking at https://github.com/NixOS/nixpkgs/pull/169793 again. I think to do this properly we need to change the release.nix infrastructure to just use full triples everywhere. But that's going to be a huge amount of work, so I think I'm going to have to try to split it up. | 10:34:27 |
 John Ericson | Alyssa Ross: yeah I see | 13:50:09 |
| John Ericson | that change sounds good to me! | 13:50:18 |
| Alyssa Ross | cool :) | 13:56:17 |
| Alyssa Ross | hopefully I'll have a start by tomorrow | 13:56:38 |

3 failed tests on bison I'm just assuming this is an issue introduced by binfmt so I'm back to x86_64-linux cross compiling. currently on the kernel | 14:18:06 |
