Missing hyprland header files on NixOS (hyprland/src/desktop/Window.hpp not found) about hy3 HOT 4 CLOSED

I had the same issue under Debian unstable, it was caused by an too old version of hyprland being installed
See also #89 which describes the files moving

A git pull and build of the latest Hyperland did however cause another issue due to and change in API in Hyprland
See: #94

from hy3.

If I understood correctly,

hyprland.url = "github:hyprwm/Hyprland";

should set the hyprland source to the github version, what shoud be up to date.
Also is the Package in Home-Magager set to inputs.hyprland, what should be the above declared version.

from hy3.

I unfortunately have no experience with building Nix packages.

I just build hy3 using my old hyprland install and had the same issue as you, and pull'ing my hyprland build, rebuilding and installing it fixed it, as it made the hy3 code align with the hyprland code.

Anyway I'm 99% sure you current build issue is caused by it being build against/using an too old version of hyprland

from hy3.

Ok, I had some fundermental issues understanding the way to upgrade nixos.

The flake.lock preserves the versions for consistency and adding the --upgrade flag on nixos-rebuild doesnt change the flack.lock. So I had to run nix flake update to update my system.

Anyway you were right and thanks for beeing that persistent. I wouldn't have recognized my mistake otherwise.

Should I open a new Issue regarding the new error I get now?

I am gonna close this Issue now because the initial problem is fixed.
