	Dennis joined the room.	19:58:37
Dennis	Hi! Is there a "standard" way to get a complete cross-compilation toolchain for `riscv64-unknown-linux-gnu`? Some `pkgs.*` that I can put into `environment.systemPackages` and get the basic tools I'll probably need? (From Gentoo I'm used to `sys-devel/crossdev` that would install these tools for me. But maybe the approach would be different on NixOS?)	20:51:27

Alex	* `pkgsCross.riscv64.buildPackages.stdenv` sounds like what you're looking for.	20:52:42
Alex	(FYI: I mistyped `buildPlatform` instead of `buildPackages`)	20:53:38
Dennis	Can I get a list of these `pkgsCross`? I saw that mentioned elsewhere (for a specific binary), but could find it on https://search.nixos.org/packages, and I am still regularly struggling to find anything in https://github.com/NixOS/nixpkgs/.	20:56:27
Alex	The easiest way of exploring them is probably to use the Nix REPL. Run `nix repl '<nixpkgs>'` then type `pkgsCross` and press tab.	20:57:53
Alex	Btw you probably shouldn't be installing dev tools in `environment.systemPackages`. It's generally preferred to write a project-specific `shell.nix` file (or use `nix-shell` without one, e.g. `nix-shell -p pkgsCross.riscv64.buildPackages.stdenv`).	21:00:11
Dennis	Thanks! I'll try that. I am still very new to using Nix/NixOS for anything other than managing my physical system...	21:47:40

Tristan Ross	17 derivations to go until NixOS native RISC-V.	04:30:29
Tristan Ross	It's done. After a month, I have NixOS built natively for RISC-V.	20:40:10

Mel	In reply to @alex:tunstall.xyz Can you characterise what's wrong with the newer versions? oh sry i didnt see anyone replied ^^; i was just looking for resources if someone had actually done it, maybe i missed something meow ..	01:01:20
Mel	ill get back to the th chips later maybe ill have some specific problems again, right now im back to the starfives lol :3	01:01:58
Mel	In reply to @rosscomputerguy:matrix.org It's done. After a month, I have NixOS built natively for RISC-V. oh hell yea!! do u have ur configuration public somewhere ? ive been trying to do something similar recently meow!!	01:02:59

liberodark	Hi, I want to install nixos on VisionFive 2 for make build.	12:12:20
liberodark	* Hi, I want to install nixos on VisionFive 2 for make builder.	12:12:27
liberodark	You have a way for that ?	12:12:41
liberodark	Or i need to use debian for build inside with nix ?	12:16:34
misuzu	You can try these images https://github.com/misuzu/nixos-vf2/releases/tag/0.8 But you'll need upstream u-boot on spi I'm using https://github.com/misuzu/nixos-vf2/releases/download/0.7/u-boot-spl.bin.normal.out https://github.com/misuzu/nixos-vf2/releases/download/0.7/visionfive2_fw_payload.img	14:12:27
Tristan Ross	In reply to @liberodark:matrix.org Hi, I want to install nixos on VisionFive 2 for make build. I just used the SD card as an installer and do things like normal	14:21:51
liberodark	Im using only a NVME if you have iso for try this.	14:22:33
liberodark	* Im using only a NVME if you have iso for try this?	14:22:38
Alex	In reply to @liberodark:matrix.org Im using only a NVME if you have iso for try this? For NVMe boot, you need the SPL (u-boot + OpenSBI) in flash (recommended), eMMC, or microSD. With all that done, most VF2 images should work fine (e.g. the one misuzu linked).	14:25:27
