I have Soprano and the other files. Maybe i need a newer version? I'm running 1.2.9 I think regards MAC >Hi Mac, >seems somewhat complicated, i work on compile kde4.4.2 since 2 weeks. >I did download and compile half the internet, sorry, i dont rememner exactly what i had done to get this particular problem goes away ... >But i remember something: I did resolve most of the "optional" dependencies. >Looks like each of them is optional but at least one is needed. >And btw: in most cases its not enough to have these components installed, you may need the development version of them often. Seems the only way to cure this problem was to use kdesupport-for-4.4 as opposed to kdesupport TRUNK. TRUNK was okay for kde-4.4.1 but not for 4.4.2, not for me anyway and I don't know why. As an aside. Polkit-qt-1 is not present in kdesupport-for-4.4 so I downloaded and installed the latest version from online. Doing this caused problems with PolKit-KDE-1 which complained about missing libraries and version nos. In the end I had to install polkit-qt-1 from kdesupport TRUNK! This cured the problem.
