Did it work with previous versions of Hyprland?

Do you have the wlr/backend.h file on your system? On my system (Arch), it's located in /usr/include/hyprland/wlroots/wlr/backend.h.

before updating my flake hyprland was at 589f758d947cb4e8b888d2da00076a9fb0a6d521 and split-monitor-workspaces was at 65d4cb11a27f8c0e6aa976e5d1c17d9086469938, haven't bisected yet, will do that tomorrow most likely if it's not related to this hyprwm/hyprland-plugins#164

it's built by nix, the derivation should have all the correct dependencies - if that's the case it'll most likely be fixed when this gets merged hyprwm/Hyprland#5952

[zjeffer]

That PR has now been merged, can you try again?

[jacekpoz]

still broken but just built with hyprwm/Hyprland#6002 and it works, I'll close this when that PR gets merged

[jacekpoz]

merged and fixed, closing
