[PeterBadzhakov]

Both default AUR PKGBUILD and using the one provided in the README.md of this repo lead to an error in compilation.

System: Manjaro 20.0.3 Lysia, x86_64 Linux 5.7.0-3-MANJARO, KDE 5.70.0

KDE 5.70.0

That is the version of Frameworks. What about the version of Plasma? I am sure it is 5.18.

You may want to follow the in- wait... So this also happens with the 5.18 PKGBUILD?

[PeterBadzhakov]

Sorry for the lack of information. Checking currently installed packages:

plasma-desktop: 5.18.5-2 plasma-workspace: 5.18.5-3 plasma-framework-git: 5.71.0 Qt dependencies are all version 5.15

After the original PKGBUILD failed, I cleared my AUR cache and substituted them with your files from the README.md repo. Build failed on the same spot for the same reason.

[tildearrow]

Hmm... Is there any reason why are you using plasma-framework-git instead of the normal plasma-framework?

[PeterBadzhakov]

It failed with the default one so I figured I need newer code. I usually prefer to compile from source but it's never been a problem.

Hmmm... Can you try again with the non-git Plasma framework and the 5.18 PKGBUILD?

[PeterBadzhakov]

Installed default plasma framework and cleared cache. With your PKGBUILD:

Build failed pastebin diff of build files, am I doing something wrong?

[tildearrow]

Hmmm.... nope. You seem to be doing everything correctly.

What is the version of kscreenlocker?

[PeterBadzhakov]

kscreenlocker: 5.18.5-1

I reinstalled it and build kwin-lowlatency successfully! I don't know what covertly changed.

[PeterBadzhakov]

Confirming kwin-lowlatency works flawlessly. Thank you very much for the assisstance. Great code.
