4 qt versions?
 

I am trying to run the configure script of a piece of software. The variable $QTDIR is set to /usr/lib/qt-3.2.1 but during configure the line where it checks for qt states that I have qt-3.1.2. In /usr/lib I have four different qt directories: qt, qt-3.1, qt-3.1.2, and qt-3.2.1. So, how do I make configure see the newest version of qt and do I really need four qt versions installed at once?

Thanks.

The program may not use QTDIR, look if it has an option to specify QT location.
You daon't need all four (/usr/lib/qt may be a symlink - in such case there would be 3) QT versions (in most cases). You should be able to remove one or two, but there may be software using it.
