 Corngood | Are you able to share the whole thing somewhere? | 11:58:16 |
 Manuel Bärenz | Unfortunately not, it's closed source :/ I'll try and work out a completely parametrized thing and share that | 12:55:08 |
| Corngood | I think the problem is that makeWrapper is moving the dotnet executable? | 13:17:10 |
| Corngood | can you share the contents of the wrapper script? | 13:17:41 |
| Manuel Bärenz | I guess I'm a step further. Instead of trying to package the dlls directly, I'm now trying to package a simple web service for which I have the source code (including .csproj, NuGet.config and .sln) which depends on the dll | 13:17:43 |

| Manuel Bärenz | (I needed to do this anyways at some point, but I thought it was smarter to leave out that part for later. Probably wasn't.) | 13:18:14 |
| Manuel Bärenz | Either way this is what I have right now:
{
lib,
dotnetCorePackages,
makeWrapper,
stdenvNoCC,
}:
let
url = "${customNugetServer}(Id='${pname}',Version='${version}')/Download";
dlls = dotnetCorePackages.fetchNupkg {
inherit url version pname;
sha256 = "sha256-xEPmYA0wkQrDBl82HDa6khIMltNUV5gdzayt6J1Lwpw=";
};
in
with dotnetCorePackages;
buildDotnetModule {
inherit pname version;
src = webapi-src;
buildInputs = [
aspnetcore_9_0
dlls
];
dotnet-sdk = sdk_9_0;
dotnet-runtime = runtime_9_0;
}
| 13:19:08 |

| Manuel Bärenz | I would have thought that the package is part of aspnet, but either it isn't or I'm adding dependencies incorrectly | 13:20:42 |
| Corngood | You probably need to add nuget deps: nugetDeps = ./deps.json, and then run $(nix-build -A [pkg].fetch-deps) | 13:23:59 |
| Corngood | Also putting aspnetcore_9_0 in buildInputs is unusual. You might just want to use it for dotnet-runtime. | 13:26:10 |
| Manuel Bärenz | That seems like some great piece of tooling. Right now it fails because of some proprietary dependency from our partner, but it did download a bunch of packages that seemed sensible | 13:32:39 |
| Manuel Bärenz |

Sorry, that sounded sarcastic, I meant it seriously 😅 and thanks for your help so far
| 13:41:53 |
| Manuel Bärenz | Can I point the fetch-deps to a custom nuget server for some packages? Or at least pass it a NuGet.config that has the custom server configured? | 13:46:14 |
| Manuel Bärenz | Ohh. I think if I name it properly (nuget.config instead of NuGet.config) it detects it automatically. | 13:53:13 |
| Corngood | Did you get a complete deps.json then? | 14:09:51 |
| 27 Oct 2025 |
| Manuel Bärenz | No, the fetcher failed and didn't create a deps.json. I'll try again soon when I get the complete closed source dependencies from our partner | 08:32:51 |

 Emma [it/its] | question, how do i use the fetchdeps thing with the nix cli? | 19:31:00 |
| Emma [it/its] | doing a nix build .\#thing.passthru.fetch-deps && ./result fails with this:
/nix/store/q38z0zig1346h47vyianirr25fi9g42m-fetch-deps.sh: line 10: /nix/store/rxf86xrfxhij48hjqgysi8blj2c9hg88-source/ArcaneLibs.Blazor.Components/deps.nix: Read-only file system

doing a nix build .\#thing.passthru.fetch-deps && ./result fails with this:
/nix/store/q38z0zig1346h47vyianirr25fi9g42m-fetch-deps.sh: line 10: /nix/store/rxf86xrfxhij48hjqgysi8blj2c9hg88-source/ArcaneLibs.Blazor.Components/deps.nix: Read-only file system
You can't use .# because that'll be a read-only copy. Try -f . instead | 19:33:03 |
| Emma [it/its] | oh apparently you can just pass a path... lol | 19:33:05 |
| Emma [it/its] | that fails because i dont have a default.nix... lol | 19:33:38 |
| Corngood | You can pass a .nix file path instead of . | 19:34:14 |
| Emma [it/its] | i have a flake.nix | 19:34:26 |
| Emma [it/its] | thats the only .nix file i have | 19:34:29 |
| Emma [it/its] | (i dont want to maintain 6 identical copies of the same file when they only differ in at most 2 lines) | 19:35:22 |
| Corngood | Oh, you can also pass a path to fetch-deps itself to override it. That might be easiest | 19:35:27 |
| Emma [it/its] | yep discovered that one already | 19:35:38 |
| Emma [it/its] | but i guess that's my best bet | 19:35:44 |
