Hello all! First I must say that SuSE Linux is a fantastic product! It works great, even on my slow computer! Now for the real question: I have SuSE Linux 8.0 Professional, and I use KDE 3.0 (as profided on the CD). Now I want some extra programs for KDE, like Kopete and SuperKaramba. The problem with RPM's is that I always have dependency problems. So I tried to compile Kopete and SuperKaramba myself, but I failed. I got this message: checking for Qt... libraries /usr/lib/qt3/lib, headers /usr/lib/qt3/include using -mt checking if Qt compiles without flags... no checking for moc... /usr/lib/qt3/bin/moc checking for uic... /usr/lib/qt3/bin/uic checking whether uic supports -L ... yes checking whether uic supports -nounload ... yes checking if Qt needs -ljpeg... no checking for rpath... yes checking for KDE... configure: error: in the prefix, you've chosen, are no KDE headers installed. This will fail. So, check this please and use another prefix! I searched through my config.log, but couldn't find anything. I found out parts of KDE where in the /opt/kde3 folder, so I did ./configure --prefix=/opt/kde3 , but the same problem again. What do I need to do? Help me PLEASE!
