 fufexan | compiling perl lol | 10:21:49 |
 matthewcroughan - nix.how | native compilation produces paths like /nix/store/foo whereas cross compiling is like /nix/store/riscv64-foo | 10:22:26 |
| matthewcroughan - nix.how | so if you do nix-shell on the board, it's not going to have /nix/store/foo since you didn't compile natively | 10:22:45 |
| matthewcroughan - nix.how | so no paths match | 10:22:48 |
| matthewcroughan - nix.how | you have to deploy to the board | 10:22:51 |
| matthewcroughan - nix.how | go to my flake, make a change to the configuration.nix, then nixos-rebuild switch --flake .#visionfive-cross-x86 --target-host user@board | 10:23:14 |
| fufexan | can a binfmt'd host build native paths? or is it just cross compiling? | 10:23:30 |
 dramforever | I guess you can nix shell github:{forked-nixpkgs}#legacyPackages.x86_64-linux.pkgsCross.riscv64.lm_sensors with a builder | 10:30:12 |
| matthewcroughan - nix.how | that's true | 10:34:04 |

can a binfmt'd host build native paths? or is it just cross compiling? binfmt is native yes | 10:34:24 |
| dramforever | well honestly I just steal packages from NickCao
nix run --extra-substituters "https://cache.nichi.co" --extra-trusted-public-keys "hydra.nichi.co-0:P3nkYHhmcLR3eNJgOAnHDjmQLkfqheGyhZ6GLrUVHwk=" github:NickCao/nixpkgs/riscv#legacyPackages.x86_64-linux.pkgsCross.riscv64.lm_sensors | 10:37:23 |
| dramforever | really saved me a lot of time when i was trying to get some weird images going | 10:38:01 |
| fufexan | great, cooking up a configuration.nix based on what you suggested | 10:38:42 |
| fufexan | can I somehow make github:NickCao/nixpkgs/riscv#legacyPackages.x86_64-linux.pkgsCross.riscv64 an installable? so that I can just run nix shell np-riscv#<package> and it would expand that automatically? | 10:47:14 |
| fufexan | or I guess I could make a global alias in bash/zsh | 10:47:23 |
| dramforever | might be a good idea | 10:55:07 |
| dramforever | i mean, adding it to flake.nix | 10:55:14 |

or I guess I could make a global alias in bash/zsh so that alias did not work, will have to think of a different way to make it work | 10:08:11 |

also fixed this by enabling riscv64 binfmt on my machine | 10:08:32 |

 luizribeiro | in case any of you are interested, I’ve been collecting all my riscv64 patches on this repo: https://github.com/luizribeiro/nixpkgs-riscv
there’s a bunch of stuff I’ve had to do to get my usual setup to run on the visionfive. stuff like getting llvm to build, building a go bootstrap compiler for riscv64 (they don’t provide one), etc.
I’m putting up PRs but it will take a while for all of it to get upstreamed | 02:15:13 |
| luizribeiro | (it’s obviously based on the awesome work by others who have put up PRs to get the visionfive to boot, of course :) all I’m doing is getting the packages I couldn’t build fixed) | 02:15:53 |
