Hi. After a recent update to qt45 it looks like my lancelot got broken.
It uses 100% CPU all the time (one core at a time, e.g. 1 core has ~5%, second 100%, and after a minute or so core one has 100%, core two ~5%)
Second thing is that I cannot open the programs sections. I mean, the program categories don’t open even though I click on them. I heard there is a patch on lancelot bugzilla for qt45 :
So, the only way to fix this would be to compile lancelot? I found instructions on lancelot’s site, but first, how do I remove the old lancelot and apply the patch after I copy the code from SVN?
Ref; to this and your other post about fonts.
Who told you to use QT45
Some I know have been using it with 4.2.2 also, but officially it’s not recommended as I recall.
I have no added QT repo and it’s all just fine.
I don’t know - it just installed, I didn’t change anything in my repos. But FYI, I’ve got many repos, but I think I can manage them correctly - there haven’t been any problems for a while, and qt45 seems to fix some of the problem I had before. (system tray renders properly, menu icon now has the correct size)
If something is wrong, you can tell me.
Anyway, I’ve tried to apply the patch to the lancelot code I downlaoded from SVN, but it seems that it’s already there, so the issue is fixed. There are just no packages for newer lancelot, so I must compile it myself. I had to install newer cmake version from developer repos, and I still get an error:

I tried making these subdirectories myself and removing this code from CMakeLists.txt and it successfully finished. But even though there is ‘Makefile’ file, running ‘make’ does nothing.

KDE:KDE4:Factory:Desktop now contains Qt 4.5 in anticipation of KDE 4.3 Beta moving in soon and KDE 4.2.3 builds against it. Seems people like to continue using it despite all warnings and pointer about KDE:42.
I’ve already compiled some things on KDE4, but these mostly have been plasmoids, so compiling wouldn’t be a big issue. But if the patch doesn’t help, well… So there is really no way to run Lancelot with qt45 currently? I was happy I finally got neat system tray! (no ghosting icons).
And with older qt I needed to resize the bottom panel all the time because the lancelot icon was too small - with qt45 it works ok, so I’d prefer doing a rollback only after I know there is no way to achieve working Lancelot.
