 emily | should be landing in staging soon | 09:16:19 |
| emily | plan is to update LLVM for Darwin and other platforms in lockstep in future | 09:16:59 |
| emily | which should be very good for LLVM in general, because we're the only ones building most of the package set with it | 09:17:12 |
 p14 | Very cool to have gotten things into this state. | 09:17:13 |
| p14 | It (the state of nixpkgs generally and the llvm side specifically) is a seriously impressive thing. | 09:17:55 |
| p14 | Would be nice if more stuff built happily out of the box with clang. | 09:18:03 |
| emily | the more we take an upstream-first approach the more the ecosystem will move in that direction :) | 09:18:24 |
| emily | I'd rather Linux was using LLVM personally! | 09:18:39 |

I've been having too much LLVM fun myself already lately: https://github.com/NixOS/nixpkgs/pull/354107 eh I broke eval on that one -- will fix. | 09:19:39 |

The failures mentioned in https://github.com/NixOS/nixpkgs/pull/354471 raise my eyebrows a bit, not sure what's going on there. should maybe just send this to staging so you can do the --replace-fail thing? | 09:19:46 |
| p14 | I mean, I could also do replace-fail in a separate patch. | 09:20:04 |
| emily | sure :) | 09:20:09 |
| p14 | But it's only a warning right now so not especially motivated to fix a single package. | 09:20:22 |
| p14 | Though, is this the kind of thing that can even be done treewide? :hmm: | 09:20:39 |
| emily | that was just being talked about in the dev room | 09:21:41 |
| p14 | Failing at first hurdle here emily - I was under the impression nostdinc was somehow conditioned on the target, or that darwin had a fix for it somehow, but I see it unconditionally here: https://github.com/NixOS/nixpkgs/blob/52bf1163fadb7ee5e21ee0b8e5cf266acb3e74e9/pkgs/development/compilers/llvm/common/default.nix#L533 | 09:21:52 |
| emily | I think yes as long as the people who do it actually show up to the staging-next cycle to fix everything | 09:22:00 |
| emily | because there'll be a lot to fix | 09:22:05 |

| emily | which is where I added the conditional | 09:22:56 |
| emily | (to unbreak Darwin stuff) | 09:23:01 |
| p14 | Gotcha. | 09:23:03 |
| emily | FWIW, the condition is Darwin host and Darwin target, but we can probably relax that to Darwin target. | 09:23:21 |
| emily | there's some iffiness around using the compiler outside the sandbox without an SDK to do Linux-to-Darwin cross but… eh… | 09:23:40 |
| emily | Linux-to-Darwin cross doesn't even work yet for one | 09:23:56 |
| emily | and when it does the divergence will become annoying | 09:24:00 |
| p14 | https://matrix.to/#/!ayCRiZriCVtuCUpeLp:nixos.org/$qpO1aqKQfb-3zGKi_wHlLgQ-nCND4chY_Tc5kHQHqNQ?via=nixos.org&via=matrix.org&via=tchncs.de was just asking about linux-to-darwin cross. I was under the impression it isn't possible. Is there a way? | 09:24:29 |
| emily | I'll reply there :) | 09:25:03 |

should maybe just send this to staging so you can do the --replace-fail thing? I sent this as a separate patch. https://github.com/NixOS/nixpkgs/pull/356120 | 09:52:50 |
| p14 | Currently untested while I await a bunch of staging to build. Is there some automated on-PR testing available? | 09:53:30 |
