Chris > How do I compile an app that requires QT 1.4 when I have QT 2.x? You can have separate QT folders. Then when you do the compile you can point the compile at the separate folder. Can't remember where the QT compile howto is for this. It's either on the QT site or the KDE site. I used it to compile and build the pre-release version of KDE 1.9 and 2.0 so that I could use 1.9x with the 1.0 version. I'm sure that someone else will come up with a better answer than this ?
