Upgrading installation

[Djony]

Hi, I have Fedora Core 5 and Qt version 3.3 installed on this Linux distribution. How can I upgrade Qt to 4.1.4?

Either see if there are any RPM:s available out there or get the source, configure it and build. Just make sure to add some sort of prefix to the files so that you do not mix the qmake from Qt 3 with the Qt 4 version.

The easiest way to avoid mixing up the files, is to install Qt4 to it's own directory, and not mix it in with the qt3 locations. Then use a script to switch QTDIR and PATH between the two. If you build from source, the default location will be /usr/local/Trolltech/Qt-4.2.x.
