@reckenrode:matrix.orgRandy EckenrodeRelocatable store seems like it would have the same difficulties as CA derivations with needing to update path references.19:58:13
@reckenrode:matrix.orgRandy EckenrodeI’d rather see CA derivations stabilized if I had to choose.19:58:35
@rosssmyth:matrix.orgrosssmyth joined the room.20:48:00
@rosssmyth:matrix.orgrosssmyth I really like the work that has been going into stdenv recently. Primarily from Tristan Ross (though others too). I try silly stdenv stuff at work often and the work being done make it more possible to do in the future. 21:02:18
@rosssmyth:matrix.orgrosssmyththanks21:02:19
@rosssmyth:matrix.orgrosssmyth376197 is one I am looking forward too because I tried wrestling pkgsCross in the past and the way the CPU attributes are setup now made it harder than it needed to be 21:04:20

Yeah, that PR is delayed because the toolchain attributes PR is needed.

@rosssmyth:matrix.orgrosssmythI work in embedded, so I've found some fun corners of the pkgsCross system that lead to me mainly giving up on using it for now. One is that cmake's targets are not the same as clang's, so for certain triples compiler-rt seems to be built for the wrong target. I think that was the outcome of one afternoon of staring at logs a couple months ago.21:12:53
@rosscomputerguy:matrix.orgTristan Ross Yeah, that's one of the use cases that I had thought of for the platform improvements 21:14:58
@rosscomputerguy:matrix.orgTristan RossThe idea is to be able to manipulate as much as possible.21:15:10
@rosscomputerguy:matrix.orgTristan Ross There's obviously combinations which don't work 21:15:35
@rosscomputerguy:matrix.orgTristan RossBut there's combinations which would work and it would be better than what we can provide currently.21:15:58
@reckenrode:matrix.orgRandy EckenrodeIf the cross situation can get to the point where building stuff with Wine is less painful, that would be great.21:59:01
@reckenrode:matrix.orgRandy Eckenrode* If the cross situation can get to the point where building Wine (and DLLs for Wine) is less painful, that would be great.21:59:44

@rosssmyth:matrix.orgrosssmythSo far I've found building with mingwW64 to be pretty easy. I have a Rust DLL I ship to customers I build with Nix. 15:44:20

@rosssmyth:matrix.orgrosssmythAnd my setup is basically this https://github.com/RossSmyth/rustNixExample/blob/rustTemplate/flake.nix15:45:02

@aleksana:mozilla.orgaleksana 🏳️‍⚧️ (force me to bed after 18:00 UTC) Not sure if here is the place to ask it, but why don't we set __darwinAllowLocalNetworking = true in darwin stdenv? 16:08:32
@aleksana:mozilla.orgaleksana 🏳️‍⚧️ (force me to bed after 18:00 UTC)This is causing problems for contributors, just because the situation on darwin platform is different from Linux, and people without a machine don't know how to properly fix it.16:10:23
@aleksana:mozilla.orgaleksana 🏳️‍⚧️ (force me to bed after 18:00 UTC)And it's even undocumented16:14:50
@emilazy:matrix.orgemilyit's a purity hole17:23:53
@emilazy:matrix.orgemilyDarwin doesn't have network namespaces, Linux does17:23:57
@emilazy:matrix.orgemilyin particular you can puncture the sandbox with it somewhat, although the Darwin sandbox is moderately porous to begin with17:24:28
@emilazy:matrix.orgemily see e.g. https://github.com/NixOS/nix/pull/11270#issue-2456432178 17:25:03

That's pretty unfortunate
17:49:09
@aleksana:mozilla.orgaleksana 🏳️‍⚧️ (force me to bed after 18:00 UTC)But what we are mostly doing now is just enabling it for derivations needing it17:50:07
@aleksana:mozilla.orgaleksana 🏳️‍⚧️ (force me to bed after 18:00 UTC)instead of e.g. skipping related tests17:50:37
@emilazy:matrix.orgemilyright. well I don't think it's a problem to set when needed17:53:44
