 alexfmpe | * nix-build --keep-going will spit out all the ones that failed - i.e. the ones who need the tests to stay disabled | 12:08:35 |
| alexfmpe | * taking
dontCheck as an example:
I have a .nix file that filters haskellPackages and filters for all derivations with doCheck == false, then does doCheck = true for all of them | 13:51:44 |

| alexfmpe | if that step turns out to be wonky, can always inject an easily grepable "I built" on the checked packages
overrideCabal (old: {
postFixup = ''
${old.postFixup or ""}
echo "Override no longer needed for ${old.pname}"
'';
})

| alexfmpe | at the cost of extra builds due to --check | 14:11:25 |
| alexfmpe | ah huh actually that won't work because --check errors if the input hasn't been built, would need some force rebuild option | 14:13:03 |
| alexfmpe | annoying that nix doesn't output the built store paths when there were also failures | 14:13:31 |

annoying that nix doesn't output the built store paths when there were also failures You could achieve this by splitting your nix-build command into a nix-instantiate (gives drv), a nix-build (realises drv into outputs), and a nix-store --query (can list outputs for drv). | 21:49:16 |

| alexfmpe | Thanks, I'll try that | 07:19:39 |
|  Axman6 joined the room. | 07:56:52 |
|  unebnf joined the room. | 07:58:14 |
 magic_rb | @axman6:matrix.org youll have to go through pkgsCross.something-something.hostPackages.ghc | 08:06:36 |
| magic_rb | Thats the general way to get a cross compiler with nixpkgs. The javascript one works, havent tested the wasm one | 08:07:06 |
| Axman6 | so pkgsCross.wasi32.hostPackages.ghc121 or something? | 08:07:59 |
| magic_rb | Something along those lines, open up a nix repl and see whats available | 08:08:20 |
| Axman6 | s/Packages/Platform | 08:08:57 |
| Axman6 | yeah doing that now | 08:09:02 |
| magic_rb | In reply to @axman6:matrix.org
s/Packages/Platform Good catch | 08:09:12 |
| magic_rb | You might end up compiling a lot from source, so get a coffee or smth | 08:09:31 |
| Axman6 | hmm, no ghc in there, nor haskell | 08:09:48 |
| magic_rb | Check the JS one, im sure i got that working in the past. So that we confirm were looking in the right place | 08:10:21 |
| Axman6 | .hostPlatform is mostly just info about the host platform, I can't see packages in there (not that I've looked hard) | 08:11:32 |
| magic_rb | Ah then hostPackages? | 08:11:43 |
| magic_rb | Dunno | 08:11:46 |
| Axman6 | there's .gcc but I'd expect that | 08:11:48 |
| Axman6 | doesn't exist | 08:11:52 |
| magic_rb | Ah | 08:11:55 |
