I was getting this error:

/build/waywallen/src/wavsen/src/video/video_decoder.cpp:272:15: error: static assertion failed due to requirement 'sizeof (static_cast<AVVkFrame *>(nullptr)->access[0]) == sizeof(unsigned int)'

    1 error generated.

Changing the assertion to 8 bytes allowed the package to compile, and it seems to run, but I have no idea what the side effects might be. If you want to test it out yourself, here's the patch:

After the newest update I am now encountering this error when running waywallen: spawn 'waywallen-layer-shell' failed: No such file or directory (os error 2); backend will not run and no displays are detected

@ZhangHua I can now compile and use it without any issue. Thanks for figuring this out.

For everyone uses cachyos and failed to build waywallen and/or open-wallpaper-engine because _deps/qml_material-build/CMakeFiles/qml_materialplugin_init.dir/./qml_materialplugin_init_autogen/mocs_compilation.cpp.o: file not recognized: file format not recognized: We have updated PKGBUILD by the advice of the upstream maintainer. Please clone the latest repository and build again. I tested it in a cachyos:latest docker image and it built successfully.

@ZhangHua if waywallen gives runtime error for you with aur qmlmaterial because it is too old, why dont you try using -git version? its upstream with github and when normal qmlmaterial on aur will update switch to it

kamikaze211 commented on 2026-05-26 13:42 (UTC)

@ZhangHua Thank you for replying, seems that using waywallen-0.1.6-x86_64.AppImage is the most simple way for me.

ZhangHua commented on 2026-05-26 13:26 (UTC)

@kamikaze211 It seems that your problem is same to @Sterophonick, @mr_nuub and those other people's. Due to that I cannot reprooduce on my machine, you may take https://aur.archlinux.org/packages/waywallen#comment-1072824 for a look, this is the only workaround I know currently, but I do not verify it. The @l1oly's solution seems that using aur/qmlmaterial instead the bundled one. That's wierd because it should be not new enough to satisfy waywallen's requirements. If I remember correctly, building will success but the runtime error will be thrown.
