when i run a x11 app on xwayland, the labwc will crash. I run labwc in vmware workstation 17.5.

Head->Desk -_- Thanks for the heads-up flxrbr. Didn't notice I missed something because I build this in a clean chroot. Fix incoming.

Edit: To clarify: if wlroots and wlroots0.16 are installed, the export in the build() function would work. Build fails.
In a clean chroot the dir is missing and therefore will find the 0.17.x version.

Can't install this new version:

<codeDependency wlroots found: NO found 0.16.2 but need: '>=0.17.0' ; matched: '<0.18.0'
Found CMake: /usr/bin/cmake (3.28.1)
Run-time dependency wlroots found: NO (tried pkgconfig and cmake)
Looking for a fallback subproject for the dependency wlroots

Please post the initial output of meson where it checks the dependencies.
And how are you building this? makepkgor some AUR helper like yay?
As of now not reproducible on my side.

Can't build :

Didn't expect a wlroots release :D
Yes, you're right bgiovanni. That dep needs to be adjusted now. And although the 0.6.6 release of labwc is around, I don't expect they will merge the wlroots 0.17 support that late.

@TrialnError: Lately the wlroots package from the main repos has been upgraded to a new major verison (0.17.0) which I don't believe is compatible with the current release of labwc. This package should probably change the 'wlroots' dep to the newly introduced package 'wlroots0.16'; otherwise people will face annoyances when upgrading their systems with labwc installed because pacman is actively trying to upgrade to wlroots 0.17.

Thanks for the quick response!

So the way I was thinking about it, the hard dependency would turn into a soft one. I figure if xwayland was needed explicitly, I can always invoke it within the autostart as a nested instance. This way, modifying a script is much easier than recompiling. And it brings me Marie Condo sense of joy in obsessively simplifying/removing cruft/stuff...

On the other hand, my record for maintenance usually descends into bit-rot due to laziness, so I am more than appreciative for the work your doing.

It is surely possible, but not in general as I want the xwayland support, scruffidog.
And unless they make use of dlopen() this stays as a hard dep.
If you want to disable xwayland support you can disable it locally and rebase this change for every update. See a possible patch below. Dunno about the savings of this, as xwayland is fairly standalone. I suspect it won't be that much.

A new release and a question: is it possible to have a wayland only version without the Xwayland ? I assume it would simplify the dependency list somewhat and minimize cruft. I believe this can be accomplished via:

meson -Dxwayland=disabled build/
