 Pol | True | 12:41:33 |
 @linus:schreibt.jetzt | definitely not the clearest arrangement... | 12:41:34 |
| Pol | Do you think using this CLI is OK ? nix-build /home/pol/Code/NixOS/nixpkgs -A wireplumber.doc --check --keep-failed -v | 12:44:06 |
| Pol | I made modification to wireplumber and I want to see if those changes are reproducible. | 12:44:25 |
| Pol | (I basically changed the src to somewhere local) | 12:44:35 |
| Pol | * (I basically changed the src to somewhere in local) | 12:44:41 |
 raboof | yeah looks like it should to me | 12:44:56 |
| Pol | When I do that, it says: | 12:44:57 |
| Pol | this derivation will be built:
/nix/store/df8slazq6r76c6lwjmvw2j6j2cbpdbk3-wireplumber-0.4.15.drv
error: some outputs of '/nix/store/df8slazq6r76c6lwjmvw2j6j2cbpdbk3-wireplumber-0.4.15.drv' are not valid, so checking is not possible
| 12:45:00 |
| Pol | But when I use: nix-build '<nixpkgs>' -A wireplumber.doc --check --keep-failed, it builds it and the message is different. | 12:45:25 |
| raboof | ah, then first do a regular nix-build /home/pol/Code/NixOS/nixpkgs -A wireplumber.doc to build the reference | 12:45:26 |
| Pol | OOOh right... | 12:45:51 |
| Pol | Thanks :) | 12:47:04 |
| raboof | https://github.com/NixOS/nixpkgs/pull/263961 :) | 12:50:37 |
 @r522:matrix.org | also, maybe --check should tell you this too? | 12:51:11 |
| Pol | raboof: We could also explain a little bit how to compare two different builds. I'm trying to find it by myself here, but I have some troubles. | 12:53:04 |
| raboof | sure... did you tru | 12:53:53 |
| Pol | So first step: nix-build -A <package>
Second step: same command with --check --keep-failed
Thirst step: What are the things to compare here? | 12:53:58 |
| raboof | * sure... did you try 'diffoscope <one> <other>' yet? | 12:54:03 |
| raboof | the end of the second step should say something like "A and B differ", which you can then diffoscope | 12:54:30 |
| Pol | Oh. | 12:54:35 |
| raboof | could probably made clearer as well :) | 12:55:06 |
| Pol | Excellent. So easy when it's explained well | 12:55:50 |
| raboof | anyone else going to the r-b summit next week btw? https://reproducible-builds.org/events/hamburg2023/ | 13:01:10 |
| Pol | I wish I could... but nope :( | 13:04:35 |
| Pol | raboof: Is there a command equivalent to nix-build -A <package> --check but using the new CLI commandS ? nix build ... ? | 15:58:29 |
| @r522:matrix.org | In reply to @drupol:matrix.org
raboof: Is there a command equivalent to nix-build -A <package> --check but using the new CLI commandS ? nix build ... ? nix build nixpkgs#hello --rebuild --keep-failed ? | 15:59:53 |
| @r522:matrix.org | (listed on https://reproducible.nixos.org/ if you've not seen that) | 16:00:34 |
| Pol | Oh thanks. Indeed, I haven't seen it. | 16:03:05 |
