 Tristan Ross | Oh, so it should be null or libstdc++? | 23:30:06 |
 emily | it should presumably be libsupc++ on Linux at least. | 23:37:19 |

Why we didn't switch to pkgconf like Arch Linux did | 03:47:24 |
| Tristan Ross | I lost the issue but we had a discussion on it, I don't remember the outcome. | 03:54:00 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Oh right, here | 03:56:15 |

| Tristan Ross | Ah yeah, it looks like it won't be too long until we can do it. If we get it merged soon, 25.11 would be the version to start transitioning things. Likely drop in 26.05. | 04:00:12 |

https://github.com/NixOS/nixpkgs/pull/394610 So it is trying to standarise this behavior?
pkg-config is patched to ignore Requires.private for --cflags without --static, whereas libpkgconf is not. I believe such a change also has to be made for pkgconf to be viable.
| 04:01:14 |
| Tristan Ross | I think so, haven't fully read into it. | 04:01:32 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | I think we should consider dropping pkg-config (at least as default) soon as it will fail to build and upstream is inactive | 04:03:12 |

I thought we had a plan to avoid that issue by using absolute paths in .pc files. I think there was even a PR. The change we need made to pkgconf is to have it support overriding variables from .pc files with environment variables like pkg-config does. Until that's implemented, we can't switch. It would likely not be very hard to implement in pkgconf upstream. | 06:10:37 |

Why we didn't switch to pkgconf like Arch Linux did @rosscomputerguy:matrix.org we don't do conditional patches if we can avoid it, the original unconditional + targeting stagimg was better | 11:07:28 |
| Alyssa Ross | I thought we had this documented even but couldn't find it | 11:07:52 |
 Randy Eckenrode | https://github.com/catchorg/Catch2/issues/2991 is broken by Clang 20. Any C++ people here have an idea what the fix is? | 13:18:47 |
| Randy Eckenrode | https://github.com/llvm/llvm-project/issues/140519 Maybe Clang bug? Fun. | 13:24:55 |
| emily | probably just disable the test? | 13:32:19 |

 K900 | It will break things | 15:29:20 |
| K900 | If we switch with just that PR | 15:29:29 |
|  nhnn joined the room. | 16:04:40 |
| Tristan Ross | Done | 20:42:34 |
 Grimmauld (any/all) | How would we even support the environment thingy? Do we actually need that in the first place or can we migrate packages using it away? | 20:45:43 |
| emily | adding support to pkgconf; the alternatives seemed worse last time we discussed | 20:48:49 |
| Alyssa Ross | it would be such a small patch | 20:49:08 |
| Alyssa Ross | I don't understand why we're spending so much time discussing it and not doing it | 20:49:16 |
| emily | if pkgconf upstream objects then hopefully we can work together to find another way to meet our needs | 20:49:28 |
| Alyssa Ross | yes, but as previously discussed that seems extremely unlikely | 20:49:43 |
| Grimmauld (any/all) | i mean, this expects we have people with the necessary domain knowledge that also have the time and motivation... Seems that never happened in the past year | 20:50:35 |
