System Info (please complete the following information):

• Linux Flavour: nixOS unstable
• Window Manager: hyprland
• Lamp Version: latest

Additional context

I'm relatively new to nixOS. Lampray was working for me on endeavourOS (installed via the AUR), but I cannot for the life of me get it to build on nixOS. Somebody responded to another issue here (#117 (comment)) (hence the cmakeFlags I added to my derivation), but no joy.

Here's my build log: https://gist.github.com/rykugur/5624d7defeca2624e5e4bc76e3361191

For reference I also started a discussion in the nixOS forums here

It looks like you are using the commit 79bac4c, which had a build error in it. Could you try using a newer commit, ideally the latest one (4673fef) and see if that helps with the build at all?

Good call... I was originally on the latest version, but that was when I first tried building this... I should have checked before making this post. 🤦

That got me further (at least no errors yet); probably need to tinker a bit more, but it's a definite improvement. Thanks!

EDIT: Wanted to follow up quick: I was able to build manually. Just missing a few system libs before I can run, but that's no big deal.

Sorry to close/reopen. I was getting a weird error, but was able to figure it out. For posterity, it was:

./result/bin/Lampray: error while loading shared libraries: liblz4.so.1: cannot open shared object file: No such file or directory

I didn't see lz4 in the docs as a requirement, but adding lz4 to my buildInputs seems to have resolved the issue and I'm able to launch the app.

I then ran into the p7zip couldn't be found issue. I was able to get around it temporarily by editing the conf.mdf file and hard-coding the path, but that "isn't really the nix way" and likely wouldn't work if I were try to import this into my nix config. I'll dig around and see if I can find a more permanent (declarative) solution.

@rykugur did you find the solution for that?

I eventually got it working in nixOS - here's my derivation. Hope that helps.
