 Daniel | Has anything changed in direnv with version 25.11?
When I run dotnet run, I get the well-known error:
Could not start dynamically linked executable... | 13:25:49 |

| tpw_rules | hi, i'm trying to package a program (https://github.com/ArduPilot/MissionPlanner) and i'm unsure of the dizzying versions of dotnet and if this is what i want | 20:37:19 |
| tpw_rules | i currently run the windows-built executables with mono under linux. but i need to build it myself on linux to fix some stuff. the .csproj says <TargetFramework>net472</TargetFramework> . is there some sort of buildmonopackage i need instead? | 20:38:41 |
 K900 | You can't probably | 20:39:56 |
| K900 | If it's 4.7.2 I don't think there's a builder that's usable | 20:40:09 |
| tpw_rules | is it possible even theoretically? | 20:41:14 |
| tpw_rules | like does mono have the compiler? | 20:42:53 |
| tpw_rules | was there something in an old nixpkgs? | 20:43:39 |
| K900 | Uhh I'm not sure how much of a compiler mono has for dotnet that old | 20:48:15 |
| K900 | You might want to just try building it with Core | 20:48:20 |
| K900 | If it doesn't use Windows.Forms it should be fine | 20:48:27 |
| tpw_rules | i'm following the path in the manual and it hasn't exploded yet | 20:48:42 |
| tpw_rules | i figured out mono is a submodule of the project which is a bit scary | 20:49:12 |
| tpw_rules | okay it exploded, the "type or namespace name could not be found" | 20:52:17 |
| tpw_rules | there look to be some strange stanzas that suggest that should be pre-compiled. i will try to rip it out and see what happens. don't think i need to narrate the whole journey | 20:55:53 |
| tpw_rules | so i've got it compiling but it crashes at runtime with some complaint about frobbing a property it doesn't like in Windows.Forms. is that cause i'm compiling against an ersatz mono version? | 22:07:04 |
| tpw_rules | well i patched the error out of my mono and it's working well enough now. | 22:34:37 |
| tpw_rules | still unclear why the official build works! | 22:34:52 |

 dgb | Hey, I updated a dotnet package and I'm seeing something really weird, I'm having to manually set DOTNET_ROOT in the preCheck phase, the tests don't run without it.
https://github.com/NixOS/nixpkgs/pull/469509#discussion_r2605320864
Does anyone know why this might be happening? | 06:07:01 |
| dgb | it feels like something I shouldn't have to do, I don't see any other dotnet packages doing it. | 06:07:34 |
|  @xsrp:matrix.org removed their profile picture. | 06:23:47 |
| @xsrp:matrix.org removed their display name srp. | 06:23:57 |
| @xsrp:matrix.org left the room. | 06:24:03 |
 Corngood | What error do you get? | 12:59:00 |
| dgb | it can't find the dotnet runtime: https://files.dgb.sh/public/bicep_tests_failure.log
I edited dotnet-hook.sh and confirmed that DOTNET_ROOT is empty when the tests run if I don't manually set it here, so it's not completely unsurprising? | 21:13:31 |
| dgb | here: https://github.com/NixOS/nixpkgs/blob/59e6d1e9ac49051644a8a3802c1531e17932c675/pkgs/build-support/dotnet/build-dotnet-module/hook/dotnet-hook.sh#L208 | 21:14:15 |
| dgb | but, before my update, DOTNET_ROOT is still empty and yet it can find the runtime | 22:06:32 |
| dgb | I am very confused :) | 22:06:41 |
