 Alex | In reply to @p14:matrix.org
I’m only building nixpkgs unmodified from upstream, No overlays or anything like that. I’m wondering if hydra stopped needing to build it? How would I tell what pulled it into the hydra build when it was working, and then look for that in today’s state? I'd probably bisect until I find the exact commit where Hydra stopped building it, then look at what changed and how it affects the build closure using nix why-depends --derivation. | 11:27:48 |
 p14 | The commit pointed to by the bisect is the binutils patch (sha mentioned above), which is suspicious. But that requires rebuilding quite a bit of stuff. | 11:30:23 |
| Alex | FWIW stdenv depends on binutils | 11:31:01 |
| p14 | (That is, a bisect without skipping bad ordinary stdenvs) | 11:31:07 |
| p14 | Yeah, the fact that commit is not a hit makes me wonder if something else went wrong? I suppose with the periodic rebuilds it could be anything between that commit and the next commit built by hydra? How would I figure out which commits were built by hydra so I can look at them? | 11:32:18 |
| Alex | Hydra builds practically every commit.
Look in the "inputs" tab for each evaluation.
The evaluations list also shows whenever an input changes version. | 11:33:43 |
| p14 | I am struggling to understand how Hydra built this derivation. I am looking at the release 2305 nixos jobset, and the oldest thing there. I searching for pkgsStatic does show something up, but not pkgsCross. | 11:40:10 |
 trofi | I would guess that only cross-trunk jobset from https://hydra.nixos.org/project/nixpkgs#tabs-project would build cross-compilers. | 15:06:19 |
| trofi | It might be that you were lucky to try 23.05 when it was very close to trunk when binaries lied around. But I could completely misinterpret it as well. | 15:07:10 |
| trofi | And looking at https://hydra.nixos.org/jobset/nixpkgs/cross-trunk there was a severe regression ~today: we lost 812 extra jobs. | 15:09:48 |

| trofi | Ah, good catch! I clicked on a few real failures, saw libgcc_s.so breakage and though the rest are the same. | 15:44:13 |

sorear: would you tell us more about what you're trying to do? :) build a package, any package, with llvm 16 ->
try using pkgsLLVM.stdenv ->
useLLVM builds a stdenv with llvm 11. I was able to override that with an overlay, but the llvm runtimes build system changed substantially between 14 and 15 and compiler-rt/libcxxabi/libunwind >=15 don't build for the hostPlatform.useLLVM=true case. After a few days I have patches to nixpkgs that let me build a pkgsLLVM(llvmPackages = llvmPackages_15).stdenv and it works for simple C programs but not C++ programs.
This was a few weeks ago, but I just joined matrix for other reasons and thought I should let people know about the ongoing project | 15:52:25 |

Would it be reasonable to put the workaround of having an empty libgcc_eh.a somewhere into nixpkgs? | 10:07:10 |

| qbit | anyone running on armv6l? :D | 17:16:57 |
| trofi | Looks intriguing (the paste seems to lack an actual error reported by gcc, and contains only the clarifying note after the error) | 21:00:23 |
