 emily | I was thinking it might be via some non-free thing, but I guess if anything substantial required people to build GHC themselves we'd hear about it | 15:00:46 |
 sterni | mysterious I was convinced that we build something that pulls in GHC on i686-linux | 17:28:26 |
| sterni | Maybe it was flac? https://github.com/NixOS/nixpkgs/pull/437543 | 17:28:52 |
 K900 | Could be | 17:29:41 |
| emily | yeah, even without that PR it looks like it'd be harmless to drop on i686-linux | 18:35:53 |
| emily | since we'd just get no man pages for something that is surely only being used as a component of stuff to host on an x86_64-linux system that can get its own flac manpages | 18:36:23 |

 ElvishJerricco | cursed knowledge of the day: the linux kernel depends on systemd because of rsync: https://github.com/NixOS/nixpkgs/pull/446259 | 06:55:26 |
| ElvishJerricco | (hi I'm trying to at least a little bit minimize the rebuild count of systemd) | 06:56:47 |
 Vladimír Čunát | gcc 15 seems to be giving up NixOS 25.11, but glibc upgrade not yet 😅 | 11:32:44 |
| Vladimír Čunát | Maybe I'd prefer not to rush it in the last allowed week either, given the concerns (e.g. around executable stack). | 11:39:25 |
 Marie | For gcc 15 we would also need this, since gcc 15 cross compilers are broken right now, because our ancient patch doesn't apply anymore

| K900 | Beautiful | 13:32:54 |
 ghpzin | Could you ref gcc15 PR, so people know there is a fix for pkgsCross/pkgsStatic | 13:35:22 |

(kind of hard to find these, already had rebase of that patch in my fork) | 13:36:12 |

| ghpzin | Maybe somebody already made PR to update musl bootstrap files, but it is also impossible to find. | 13:55:23 |

| emily | GCC 15 also needs some Darwin stuff I have locally | 18:31:27 |
| emily | probably 26.05 makes the most senes at this point | 18:31:34 |
| emily | 💜 to ghpzin for all the fix PRs though | 18:31:39 |
 Sami Liedes | Ah, I may have found the room! I've been patching a bit stuff in nixpkgs which I think probably also applies to gcc 15. (Specifically what I've been fixing is packages building with GCC 14 and -D_GLIBCXX_DEBUG, which requires things that declare themselves as random access iterators to have operator<=; but I read in some bug report that gcc 15 is also similarly picky about some iterator operators.)
Is there a branch somewhere where the proposed gcc 15 patches are collected? I could switch to that and start fixing for it with -D_GLIBCXX_DEBUG, so I would likely at the same time fix them for gcc 15.
| 18:32:26 |
| emily | those fixes can go to master just fine | 18:34:43 |
| emily | we prefer backported patches already applied upstream, then patches from other distros / unmerged patches already sent upstream by others, then patches we write and submit upstream ourselves, and only then patches that only live in Nixpkgs | 18:35:15 |
| Sami Liedes | Yes, that's understandable. My thought was it's easier to get farther faster if there's a working branch with temporary fixes even if they never get to master, because then you get to test also dependencies of what doesn't now build in master. | 18:36:25 |
| emily | usually we just maintain those locally and clean them up as we push them out | 18:38:18 |
| Sami Liedes | But obviously I can also maintain a personal branch for that :) | 18:38:22 |
| Sami Liedes | Yeah, that's what I've been doing. | 18:38:29 |
| emily | or just push them out as branches on a fork | 18:38:40 |
