I upgraded KDE to version 3.2 , using yun, on 2 systems with the identical Fedora core1 installed .
I followed the procdure described on the KDE website for both systems.
On 1 system the upgrade went smoothly, while on the 2nd one I get the following error:
error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory.
If I go to the /usr/lib/qt-3.3/lib directory, the link libqt-mt.so.3 pointing to libqt-mt.so.3.3.2 is there and of course the lib libqt-mt.so.3.3.2 is present too.
Any idea why it works on one rig and not on the other ?

P.S. I know my question is not Fedora specific and that the problem could have happened with any distro but the Fedora subforum seems like the best place to ask, unless a qt forum is created.

What do you get if you type "echo $QTDIR"?

Is there a file /etc/ld.so.conf.d/qt.conf ?

I had the same problem, but added this line to /etc/ld.so.conf:
/usr/lib/qt-3.3/lib

1) When typing "echo $QTDIR" I get:
/usr/lib/qt-3.3

2) yes, there is a file named /etc/ld.so.conf.d/qt.conf

3) When I list that file it says:
/usr/lib/qt-3.3/lib

That looks fine so I'll have to find something else.

Thanks for your suggestion toloban , you did your best.

Biased Turkey,

I think I had the same problem. I edited the file /etc/ld.so.conf, and put the /usr/lib/qt-3.3/lib entry at the top of the file; removed references to old qt libraries (especially, from versions 1.x and 2.x; you'll have them if you have upgraded from RH 6.0 onwards); then did a ldconfig. It worked.

I just have 1 entry in the /etc/ld.so.conf.
I ran ldconfig too.
So I realy don't know what else I could do.

Thanks anyway
