 dramforever | what's your nix --version | 01:40:18 |
| dramforever | this is an old nix bug that should be fixed | 01:40:34 |
| dramforever | * this looks like an old nix bug that should be fixed | 01:40:43 |
 Alison Jenkins | I discovered during the update to 25.05 that despite my PC using the same Nix code base as my personal laptop that my PC is refusing to build the 25.05 derivation as it keeps throwing an error stating: error: unsupported CPU i686 and yet the system var is set to system = "x86_64-linux"; and the laptop is building using pretty much the same code. The CPU is a AMD Ryzen 9 7950X so it is definitely not some old i686 CPU. Does anyone know how I can debug this short of bisection? I have bisected as far as I can and also searched the repo for mention of i686 and there is nothing. | 07:40:35 |
| Alison Jenkins | Sorry if this is the wrong channel for this question | 07:40:57 |
| Alison Jenkins | This one doesn't build: https://github.com/alisonjenkins/nix-config/blob/main/flake.nix#L203-L239 yet this one and all others do: https://github.com/alisonjenkins/nix-config/blob/main/flake.nix#L241-L278 | 07:42:22 |

 robsliwi | At first glance everything seems fine.. do you have some more stacktrace? What is throwing the error? | 09:27:31 |
| Alison Jenkins | It just shows it in most packages as it appears i686 support has been dropped on lots of the packages in Nixpkgs. | 09:46:21 |
| Alison Jenkins | I will get you the stack trace but it doesn't really show anything useful | 09:46:32 |
| Alison Jenkins | Download stacktrace.txt | 09:48:16 |
| dramforever | can you try nix eval --raw --show-trace github:alisonjenkins/nix-config#nixosConfigurations.ali-desktop.config.system.build.toplevel | 14:47:44 |
| dramforever | this should give you the full stack trace | 14:51:12 |
| dramforever | and point to what is actually throwing the error | 14:51:20 |

| ordnungswidrig | Hi all, I've got a flake that builds fine on all but one system. On that system I get a hash mismatch in the cache.

How to I debug this? I've updated the flake lock, I've tried unstable, 24.11 and 25.05 as the input source and nix store repair and more. I'm a little list.

| Alison Jenkins | Thanks dramforever sorry for the slow reply. Just running the command now | 17:19:17 |
| Alison Jenkins | Download stacktrace.txt | 17:20:31 |
| Alison Jenkins | I am looking through it but don't see anything interesting so far | 17:21:56 |

try nix-hash --type sha256 /nix/store/9545lc12nznckmbrsgsjy5vhvgrj5i4n-getty on your various systems and see what they have? | 17:22:10 |
| Alison Jenkins | From my understanding of it it is basically just stating that it is evaluating the openjdk-17 package and that it doesn't support i686 | 17:23:24 |
| Alison Jenkins | but the problem is I don't know why it thinks it needs to be. I need to track down what is specifying we need i686. | 17:23:52 |

| dramforever | okay. granted, it's not the most easy to read, but what you can do is pare it down a bit. there are lines inserted in the trace like "… while evaluating". if we grep while it looks much more managable | 03:14:09 |
| dramforever | we can get it down even further while evaluating derivation | 03:14:25 |
| dramforever | * we can get it down even further with while evaluating derivation | 03:14:30 |
