 Alyssa Ross | if it exists, it's busybox sh | 18:05:08 |
 artemis | im not even sure that my pi2 is like... booting the nixos image im feeding it | 21:30:15 |
| artemis | at all | 21:30:18 |
| artemis | i have been struggling to get even serial output | 21:30:25 |
| artemis | current state of the flake http://dpaste.com/5ZYQ2X66E | 21:30:45 |
| artemis | * i have been struggling to get even serial output and have so far failed | 21:30:56 |
| artemis | the raspi wiki says the pi2 uses mainline kernel. maybe i should try and switch to downstream kernel though im not quite sure how to do that | 21:31:35 |
| artemis | oh wow sd-image-raspberrypi.nix is suuuuper barebones huh? cant even change config.txt with it | 21:46:17 |

so i am stuck with the accursed raspi boot process Doesn't it have uefi support? https://github.com/ms-iot/RPi-UEFI#raspberrypi23-uefi | 15:03:42 |
 qbit | does the standard installer for pi3 use uefi? | 16:00:11 |

does the standard installer for pi3 use uefi? The installer SD image seems to use u-boot.
The hardware itself does not support UEFI, but there are firmware images you can put on the SD card to get UEFI support. If you need it, you may want to check whether Nixpkgs has packaged it already. | 21:56:38 |

Nix got a lot harder to compile than last time I tried. Lots of new dependencies with strict version requirements I don't know if you're still struggling with it, but I've had great success cross-compiling the binary tarball for 2.16.1 on x86_64, copy it to the host, then extract and run as usual. It's been easier than trying to debug confusing autoreconf errors or figure out what Debian packages provide the needed libraries.
(Though for some reason the nix commands only work for me when executed as root.)
You'll need to add riscv64 to the cross-compilation targets in the flake.nix for Nix (the package manager), then build hydraJobs.binaryTarballCross.x86_64-linux.riscv64-linux. Depending on your OS (my SBC is currently on Debian Sid), you may also need to add sandbox = false and/or filter-syscalls = false to /etc/nix/nix.conf. | 10:42:24 |
 fgaz | In the end I managed to compile it (thanks Alyssa Ross for the hint about busybox btw) | 10:44:51 |
| fgaz | My current blocker is [this](https://github.com/NixOS/nixpkgs/pull/236420) (llvm 15 won't build on riscv) | 10:48:26 |

No but it'd be nice to organize ourselves to build it :-) Maybe Domen can help, like with nix-community | 10:52:09 |

My current blocker is this (llvm 15 won't build on riscv) Hmm, at least building natively worked fine last I tried | 19:16:42 |

Hmm, at least building natively worked fine last I tried I was getting some missing register symbols or something | 19:18:07 |

Maybe Domen can help, like with nix-community I mean, we can definitely use cachix as a storage layer | 20:34:23 |

Maybe Domen can help, like with nix-community * I mean, we can definitely use cachix as a storage layer + distribution layer | 20:34:26 |
| raitobezarius | But we need a Hydra instance and remote builders "we trust" | 20:34:38 |
| fgaz | Until we have that we can just coordinate through a nixpkgs branch and push whatever we have. I bet that alone would save a lot of build time | 20:49:49 |

My current blocker is [this](https://github.com/NixOS/nixpkgs/pull/236420) (llvm 15 won't build on riscv) do you need rust if you build without docs? | 23:16:55 |

do you need rust if you build without docs? According to a quick why-depends on an x86_64 Nix, no. | 01:50:25 |
