 bglgwyng | The result is that when hip is being built, the package db contains two random packages | 13:30:49 |
| bglgwyng | Indeed, I applied setBuiltTargets to the packages, preventing the components not in plan.json from being built | 13:32:00 |
| bglgwyng | However, setBuildTargets can't prevent the dependencies in executableHaskellDepends getting built and registered to package db not necessarily | 13:32:47 |
| bglgwyng | How can I fix this issue? | 13:33:16 |
| bglgwyng | It seems that Setup.hs configure doesn't provide options to specify components to build | 13:34:06 |
| bglgwyng | . | 13:43:57 |
 maralorn | There should be an option to disable building of the executable and that should actually prevent the random dependency from executableHaskellDepends from being loaded into the package-db. (Rather certain that logic exists in the generic-builder.nix) If not or when you use another way to disable building of the executable you can do something like super.operational.override { random = null; }. | 14:13:57 |
| bglgwyng | Yes. I found the workaround but I want to fix generic-builder to handle setBuildTarget properly. | 14:33:31 |

| bglgwyng | I need a way to specify build targets in Setup.hs's configure phase to fix it | 14:47:05 |
| bglgwyng | But it doesn't support unfortunately | 14:47:56 |
 Teo (he/him) | Haskell.nix seems to pass the name of the component to configure https://github.com/input-output-hk/haskell.nix/blob/751e1561c3fbc0a5cf136a689b70bbce567852a8/builder/comp-builder.nix#L239 | 15:20:27 |

 alexfmpe | I've seen that a few times | 22:54:40 |
| alexfmpe | I ended up disabling direnv as it's been too unreliable for me | 22:56:12 |
| alexfmpe | Also kept getting into stale states forcing me to rm .direnv after a lot of "how is this possible" | 22:57:08 |

|  libman joined the room. | 05:35:06 |
 sterni | bglgwyng: as far as I know, there is no way to specify the build targets at configure time | 10:28:22 |
