Howto upgrade KDE & QT keeping old ones and how to start the new ones?
I want to upgrade my KDE and QT versions - without breaking my old ones, and keeping the old ones accessible.
I think I can do his by compiling all the source with the --prefix= line in the call to each packages' configure script. Is this correct?
But how do I run the new KDE and QT? Presently I boot in runlevel 3, and go into X with "startx" (on RedHat 9, kernel 2.4.20-8). I am guessing I will need to write my own custom "startx", which is a script?
I am envisioning a situation where I can do "startx" (to start KDE 3.1, using my old QT libs) and "startxnew" (to start KDE 3.2 using my new QT libs).
Is this at all possible? Can you run / have two KDE versions and two QT versions on one machine, but run each one seperately? How can I force the (I am guessing I will need to do this) the "new" KDE to use the "new" QT libraries, and NOT the old ones when compiling? But still have the "old" KDE find any dynamic libs it needs?
Put the -prefix= path at the start of my environment $PATH?
Any ideas or pointers?
