build issues on ubuntu

[karlstav]

I had a couple of build issues on regular ubuntu 25.10 (maybe it's more ubuntus fault, not sure)

1. gtk layer shell header not found.

I had to change:

-#include <gtk-layer-shell/gtk-layer-shell.h>
+#include <gtk4-layer-shell/gtk4-layer-shell.h>

in order to find the header.

2. old cyaml.h header
   even though ubuntu claims to have 1.4.2 version of cyaml it had a much older header that led to a lot of:

‘CYAML_FIELD’ was not declared in this scope; did you mean ‘CYAML_BITFIELD’?

fixed by cloning cyaml from here and copying cyaml.h and private.h to /usr/include/cyaml/ does not seem right, but it worked.

Damn the OG is here haha. I am running WayVes on Debian so I think it should work on Ubuntu as well, what Desktop Environment are you using on Ubuntu exactly? I might have to try ubuntu myself if the errors persist.

[karlstav]

just regular plain ubuntu with gnome

Gnome's Wayland implementation doesn't support the Layer Shell Protocol natively :( You might have to try another DE like KDE that supports it. That might explain the layer shell header bug, but the libcyaml error is still relevant. I'll try Ubuntu myself just to inspect this further.

[karlstav]

right, I do have a laptop with hyprland laying around here somewhere, maybe i'll dig it up at some point.

Okay. Meanwhile I'll try booting Ubuntu in a VM to try it out myself

Just booted Ubuntu 25.10 on a VM, and I see a bunch of these messages on the console while running WayVes on Gnome and no output like you described:

** (process:10425): WARNING **: 01:08:55.585: GtkWindow is not a layer surface. Make sure you called gtk_layer_init_for_window ()

Installing plasma-desktop and running WayVes (with and without the environment variables) works perfectly, since KDE supports the Layer Shell Protocol:

I'll try adding a fallback to display shaders in individual Windows so that it also works on Gnome.

Awesome, thanks. Helped on Debian 13 too. Even with the packages from the wiki installed, tons of build errors related to cyaml. Moving the cyaml header files manually did the trick

[Roonil]

I guess I'll directly link the GitHub link for libcyaml for debian. Will test on a couple more VMs first
