https://github.com/RossComputerGuy/dotfiles/blob/master/flake.nix#L213-L215 Using nix flake metadata, I count 5 versions of Nixpkgs amongst your inputs (2 of which are coincidentally the same). | 00:26:37 |
 Tristan Ross | Does that matter when you use overlays only and don't use packages or legacyPackages of the inputs? | 00:29:27 |
| Alex | I don't think so.
Unfortunately I have no idea how to profile Nix evaluations... I've always been able to just throw more RAM at the problem (since it's only been a problem in VMs for me so far). | 00:30:35 |
| Tristan Ross | Yeah, I'm not sure how to profile evals too | 00:31:06 |
| Tristan Ross | It would really help if I knew how to for some of my other projects lol | 00:31:27 |
| Alex | I guess the old binary search trick could work...
Remove half of the code and see how it affects memory usage.
Then focus your search onto the more memory-consuming half and repeat. | 00:35:54 |
| Tristan Ross | https://github.com/RossComputerGuy/dotfiles/runs/35174538512 huh the x86_64-linux cross is able to evail within Garnix's 5GB limit but the full system cannot | 00:37:51 |

error: cannot bootstrap GHC on this platform ('riscv64-linux' with libc 'defaultLibc')
I cannot find where this etc file is defined lol
| 02:02:49 |
| Tristan Ross | Oh, it's inside the derivation | 02:04:15 |
| Tristan Ross | Webkit requires GHC somewhere and it throws that error, I know there's a way to get around that but just trying to get the system to build purely | 02:05:09 |
| Tristan Ross | Oh, shellcheck is required which uses GHC | 02:08:01 |
| Tristan Ross | * Oh, shellcheck is required which uses GHC deep in the chain | 02:08:13 |
| Tristan Ross | https://github.com/NixOS/nixpkgs/pull/362868 didn't get into 24.11 | 02:14:24 |
| Tristan Ross | Oh, it doesn't matter that it isn't in 24.11 because that doesn't work. | 02:22:31 |
 Pratham Patel (you can mention me) | The root of the problem is this
https://github.com/NixOS/nixpkgs/issues/231537 | 03:28:59 |
| Pratham Patel (you can mention me) | You can cross compile ghc for rv64 but cannot bootstrap it natively (yet) | 03:29:24 |
| Tristan Ross | Yeah, I was looking at the issue | 03:34:49 |
| Tristan Ross | The problem is there's code to disable shellcheck on incompatible problems | 03:35:04 |
| Tristan Ross | And the problem is that check does not work | 03:35:12 |
| Tristan Ross | nixos-unstable should have it, I pointed the config to that and yet it still errors | 03:38:33 |
| Tristan Ross | Ok, master branch works | 03:46:50 |
| Tristan Ross | Wait, is the nixpkgs issue tracker wrong lol? It says the PR made it through fully | 03:48:47 |
| Tristan Ross | Yay, we've gotten passed eval. Now time for like 2 weeks of compiling. | 03:55:44 |

And the problem is that check does not work I "broke" the check when I added support for cross-compiling GHC. All you need to do is override the default GHC to disable building it for the RISC-V platform such that the check functions as originally intended. | 22:22:06 |
