 trofi | you can plug it into your derivation as NIX_DEBUG="1"; as another variable, or do an usual .overrideAttrs. | 06:20:11 |
 rhelmot | okay, thank you! | 06:20:45 |
| rhelmot | ah shit I see. it's mad about freebsd's libpthread.a | 06:29:49 |

 artemis | anyone know how i might cross build an armv6 image? (targeting pi zero) | 11:37:55 |
| artemis | theres a `pkgs.pkgsCross.armv7l-hf-multiplatform` that works for the pi2 but i dont see an armv6 | 11:38:17 |
 Linux Hackerman | artemis: pkgsCross.raspberryPi is intended to work on all pis AFAIU | 11:40:01 |
| artemis | oh i didnt know that existed | 11:40:13 |
| artemis | ill give it a try | 11:40:23 |
| Linux Hackerman | (but aarch64 is preferable on the newer ones that support it) | 11:40:28 |
| Linux Hackerman | (since it has binary cache coverage on native builds) | 11:40:41 |
| artemis | naturally | 11:41:15 |
| artemis | pkgsCross.raspberryPi does indeed seem to be downloading an armv6 compiler. cool | 11:41:50 |
| artemis | why is that named raspberryPi instead of something more generic | 11:42:18 |
| Linux Hackerman | historical reasons, mostly | 11:47:43 |
| Linux Hackerman | there's a raspberrypi "platform" in nixpkgs which also defines things like a kernel defconfig | 11:47:53 |
| Linux Hackerman | there are plans to make pkgsCross more consistent, afaik | 11:48:22 |
| artemis | tangentially to this, can i nix-copy-closure (or whatever i actually want if its not this?) to just like, a mounted partition | 11:53:33 |
| Linux Hackerman | nix copy --to /foo will copy things to /foo/nix/store | 11:54:00 |
| artemis | sweet ok | 11:54:06 |
| Linux Hackerman | using chroot stuff | 11:54:15 |
| Linux Hackerman | if you want to boot from it, make sure to do the copying as root | 11:54:27 |
| Linux Hackerman | otherwise the ownership will be on your user and things will be unhappy | 11:54:44 |
| artemis | is that the correct way to update a NixOS partition too? Like will that "activate" the new config or what have you | 11:54:55 |
| artemis | or do i need to do something else on top to do that | 11:55:04 |
| Linux Hackerman | with cross it's a bit tricky | 11:55:33 |
| artemis | right now im updating a crossbuilt pi2 i have but im doing that over the network with deploy-rs | 11:55:36 |
| artemis | and deploy-rs handles all the specific nix stuff for me so i only sort of know what its actually doing | 11:56:05 |
| artemis | but it like copies over my crossbuilt packages, sets up a new boot environment with an entry in the boot menu and everything | 11:56:25 |
| Linux Hackerman | because the tools that generate bootloader config and stuff are only compiled for the target arch, so you can't properly switch to the config from a different machine | 11:56:25 |
| artemis | * but it like copies over my crossbuilt packages, sets up a new boot environment with an entry in the boot menu and everything, and activates it | 11:56:29 |
