Hi! It's my first day with nixos. I tried to compile a rust project. To do so, I used a nix-shell with the content from here: https://nixos.wiki/wiki/Rust with the "Installation via rustup" option.

Unfortunately the compilation fails:

$ cargo check
   Compiling libc v0.2.151
   Compiling proc-macro2 v1.0.73
   Compiling serde v1.0.193
    Checking once_cell v1.19.0
   Compiling thiserror v1.0.53
error: linker `aarch64-linux-gnu-gcc` not found
  |
  = note: No such file or directory (os error 2)

error: could not compile `proc-macro2` (build script) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
error: could not compile `serde` (build script) due to 1 previous error
error: could not compile `libc` (build script) due to 1 previous error
error: could not compile `thiserror` (build script) due to 1 previous error

I run NixOS 23.11 stable on a VM on a Macbook with M1 (arm64) CPU.

Any ideas how to fix that?

It took me some time to work out how to get my ssh agent set up in Niri so I though I would share what I did. I'm using NixOS and Home Manager. I put this in my Home Manager config:

services.gnome-keyring = {
  enable = true;
  components = [ "pkcs11" "secrets" "ssh" ];
};
home.sessionVariables.SSH_AUTH_SOCK = "$XDG_RUNTIME_DIR/keyring/ssh";

I'm using GDM according to NixOS' default configuration which I think runs gnome-keyring (I thought I saw it in the process list before I set up the user unit), and I think that configuration is automatically unlocking gnome-keyring when I log in via PAM integration. But apparently I need to run gnome-keyring again in my window manager session. Home Manager's services.gnome-keyring adds a systemd user unit that does that.

After learning how to add an unstable overlay to nixpkgs, being able to override individual service modules from unstable was something that I still struggled with until fairly recently. Hopefully this helps someone else looking to do common-but-not-very-obvious operation.

just realized that one thing that NixOS could use is an update changelog of what packages were updated after running sudo nixos-rebuild switch --upgrade

tbh maybe there's a verbose option that I haven't discovered yet

Wow! Didn't know it'd be that simple.

Hi, I am a beginner on NixOS and I am confused how to setup fonts on it. I have home-manager working properly and nerd-fonts installed. Now how to setup System,GTK,emoji and Indic fonts.

Any article or part of config please.

I have always been exposed to windows active directory with server controlled logins, server based "home" directories, etc. With the nature of NixOS it seems like it might be easy to deploy something similar by just setting up the configuration.nix as some sort of symlink to one stored on a central server. The only issue would possibly be how to not create home directories on the local machine and instead store them on server. You might be able to make a central passwd file that gets read, but i am not sure just how secure that would be. Thoughts?

Creating infrastructure for supporting Bazel remote execution with rules_nixpkgs

I'm happy to finally release this flake; it's been on my plate for months but bigger things kept getting in the way.

Let me know here or @corbin@defcon.social if you successfully run any interpreter on any system besides amd64 Linux.

Hey, i currently try to learn the nix language and i have a question about recursion. This is my solution for Advent of Code 2015 day 4

let
    input = "abcdef";
    part1 = number:
        if (builtins.substring 0 5 (builtins.hashString "md5" "${input}${builtins.toString number}")) == "00000" then
            number
        else
            part1 (number + 1);
    part2 = "not implemented";

in {"Part 1" = part1 1; "Part 2" = part2;}

since i put the recursive call at the end of the function i assumed it would do some magic or tail call optimization stuff, but it results pretty fast in a stack overflow is there a way to get it working?

So i followed the instructions to install virtualbox and added myself to the vboxusers group, but i cant run VMs as a standard user. The GUI message says "VirtualBox kernel driver is not accessible, permission problem" the VM log says "ERROR [COM]: aRC=E ACCESSDENIED (0x80070005) aText={The console is not powered up}"

Someone on mastodon mentioned /dev/vboxdrv and that file is "crw-rw---- root vboxusers". There is also a file /dev/vboxdrvu which is "crw-rw-rw- root root" but changing that to root vboxusers with chown didnt work.

I can run VMs as root just fine. Any thoughts?

Edit: new to NixOS and really enjoying it so far

Edit 2: SOLVED: I had "virtualbox" as a package under "envoronment.systemPackages = with pkgs; [" and wasnt supposed too.

Hi all, looking for tutorials online is cool and all, but sometimes you just wanna sit down and read a physical book to understand something. So I was looking for suggestions on which books helped you the most, or which you've heard positive things about. Thanks!

I agree that dockerfile's are not very reproducible. But honestly, that's not how most people use it. I believe most people just pull the already built image which is very reproducible. Anyways, I found this video interesting and thought I'd share it and get your guys thoughts.

I've got a small haskell project and I am building it using a flake using cabal2nix based on a package.yaml file.

nix build works fine, but I have trouble with my nix develop shell. The shell is built using shellFor from haskellPackages.

Is it possible to construct a shell that contains all dependencies to build the package, but not the package itself? I tried returning the buildInputs from the packages function, but that didn't seem to have any effect. When I return my package from that function, all dependencies are available, however the package is also built - is that how it is supposed to be?

Anyone know why my dualsense controller won't show up in Bluetooth discovery? Have confirmed it shows up and pairs on my phone and used to show up on my windows machine before I switched

• It is only on NixOS this seems to happen, both my laptop and PC do this.

• Yes I have put it into pairing mode, it shows up in discovery on my phone

• The controller works perfectly when wired

• Every other Bluetooth device works with no issues

I feel like I'm missing a driver or something but no idea what, can anyone help?

I was looking into the prospect of deploying an instance of Lemmy myself. Being an ULTRA nix fanboi (and a Docker-hater), I was immediately struck by how much the process still depends on (and, IMO, is being held hostage by) Docker containers.

Can we (or at least someone more capable and with more free time than I) help the Lemmy community by harnessing the power of nix and flakes to create declarative, reproducible Lemmy scratch-built instance deployment?

I suspect it would be exceptionally easy for some of you out there. If you are a flakes power-user, just think of how much this could help the community (and perhaps awaken a few people to the power of flakes).

ps. if this already exists, please point me in the right direction.
