 alexfmpe | bisected down to https://github.com/NixOS/nixpkgs/issues/191152 confirmed I can get libffi and gmp building again by adding a && !targetPlatform.isAndroidhowver I don't understand why it matters? I'm building from nixos, there's nothing on /usr/include | 13:41:24 |
| alexfmpe | er, rather, bisected down to https://github.com/NixOS/nixpkgs/pull/356162 which fixes that issue | 13:42:12 |
| alexfmpe | I guess there's some sysroot shenanigans I don't understand going on and having -nostdlibinc is messing with it? | 13:43:50 |
| alexfmpe | hmm though... merely adding && !targetPlatform.isAndroid seems risky for non-nixos linux as /usr/include can leak there? | 13:49:30 |

 loudgolem | any reason why lib.systems.examples, examples is there | 05:51:13 |

 Artturin | In reply to @phanirithvij:matrix.org It's easier to refer to existing example platforms than to write all the attrs, some platforms have more than just

 rosssmyth | Would it be possible to add a new default/example pkgsCross system that is basically the same as arm-embedded but with newlib-nano? My goal would be to get that GCC cached so that I could use a newer GCC since it seems that latest gcc-arm-embedded update (14) PR was denied. | 18:55:20 |
| rosssmyth | I don't know what would be involved beyond adding something to the examples file, but I would be willing to do it | 19:01:07 |

| implr | I ran into https://github.com/NixOS/nixpkgs/issues/231537 while cross compiling from a x86 host to a rv64 target. I know it's fixed in unstable, but this makes me wonder about a more general problem: Shellcheck doesn't care what host arch it runs on. Theoretically, we could shellcheck the rv64 shell scripts with a host (x86) shellcheck, eliminating the need for a rv64 ghc. Is that even possible in nixpkgs? | 17:10:09 |
| implr | or am i just missing something obvious | 17:10:14 |
 bitestring | Hi, any haskell.nix experts here? Could you please share a minimal flake.nix that can compile my Haskell library to Android aarch64? Documentation did not help at all. | 17:10:48 |
| implr | nevermind, it is possible, i was just setting hostplatform/buildplatform wrong in colmena | 18:06:58 |

 rhelmot | is qt cross just totally busted? I'm failing both aarch64-linux and x86_64-freebsd cross with errors related to multiple qtbases ending up in inputs | 03:22:00 |
| rhelmot | I found https://github.com/NixOS/nixpkgs/pull/267311 but I don't parse how it would help in this case | 03:22:47 |
| rhelmot | * is qt cross just totally busted? I'm failing both aarch64-linux and x86_64-freebsd cross for qt5.qtsvg with errors related to multiple qtbases ending up in inputs | 03:23:30 |
| rhelmot | commenting out the propagatedBuildInputs/depsTargetTargetPropagated assignment on qmake-hook and that seems to fix some things but the ramifications... unknown lol. will run nixpkgs-review soon | 03:51:11 |
| Artturin | In reply to @rhelmot:matrix.orgYup and there's a few pr which may fix it | 03:59:02 |
| Artturin | Use the cross label and in:title qt5 | 03:59:24 |
 Tristan Ross | Yes, I've been wanting the issue fixed so I can get Steam "built" crossly onto aarch64 so I can do gaming on Ampere lol. It's still been broken. | 04:04:22 |
 emily | I thought Qt 5 cross was inherently broken upstream or something | 04:10:45 |
| emily | but that Qt 6 could work | 04:10:51 |
 Greg Hellings | Qt5 can be made to work, depending on target. Here's the patchset that Fedora uses to cross compile qt5 base for just Mingw targets: https://src.fedoraproject.org/rpms/mingw-qt5-qtbase/tree/rawhide | 04:40:06 |
| Greg Hellings | But that is a LOT of patches. | 04:40:16 |
| rhelmot | thanks for the hints, after a bit of tentative hacking I have cast qt5 into the shadow realm and am now building with qt6 | 07:46:50 |
