[wayland] fails to build with Wayland 1.20.0 - undefined reference to 'wl_proxy_marshal_flags'

[SupervisedThinking]

SDL 2 https://github.com/libsdl-org/SDL/releases/tag/release-2.0.18 + #5058 fails to build against Wayland 1.20.0 - 1.19.0 is fine. I guess it's related to https://github.com/wayland-project/wayland/commit/23e4a7060080ebb61f516a2edcd71ab123029c0e

Probably the same issue as here: https://bugs.gentoo.org/811840 & and the workaround LDFLAGS="${LDFLAGS} -lwayland-client" fixed it for me too.

fixed by #5092 - builds fine now, thx 👍🏻

I resolved this by mixing info coming from:

https://groups.google.com/g/linux.debian.bugs.dist/c/YmD-_Qk7YTY?pli=1
https://community.mnt.re/t/undefined-symbol-wl-proxy-marshal-flags/783

In my case the problem was that the referred libwayland showing in ldd (e.g. ldd -r krusader - or whenever executable that gives you the issue) is in /opt/admgpu instead the one in /usr/lib/x86_64-linux-gnu - do not know exactly the reason for that.
After upgrade this led to several problems (for example cannot get libgtk3 working again unless downgrading it).
Finally, the solution for me was to edit amdgpu files in /etc/ld.so.conf.d by adding /usr/lib/x86_64-linux-gnu at the first line. Then, rebuild the ld indexes with sudo rm /etc/ld.so.cache and sudo ldconfig.
This way the ldd resolves the correct linked objects and things get to work again.

Thank you very much, @CrlClgrs! A similar issue broke the SDDM display manager and therefore the login screen when upgrading from Kubuntu 21.10 to 22.04, and your instructions fixed it. The files I edited according to your instructions were 10-amdgpu-pro.conf and 20-amdgpu.conf, and they are now:

10-amdgpu-pro.conf

/usr/lib/x86_64-linux-gnu  
/opt/amdgpu-pro/lib/x86_64-linux-gnu  
/opt/amdgpu-pro/lib/i386-linux-gnu

20-amdgpu.conf

/usr/lib/x86_64-linux-gnu  
/opt/amdgpu/lib/x86_64-linux-gnu  
/opt/amdgpu/lib/i386-linux-gnu

(Editing only one of these files might be sufficient, though.)

The error message I got was:

The current theme cannot be loaded due to the errors below, please select another theme.

Hi, I have the same problem. AMDGPU driver 22.10.2.50102-1416360 - Ubuntu 20.04 - Kernel: 5.13.0-51-generic.

Any ideas?
