Hi,

I'm having some issues ith QT Designer. When I try to start it up, I get:

Code:

sohail@thabox:/home/sohail/temp/sigill$ designer
Illegal instruction
sohail@thabox:/home/sohail/temp/sigill$

So I let gdb to a backtrace on designer which got me this:

Any one else having a similer issue?
As you can see, the problem lies with some KDE library. I can remember that Designer worked fine when I had not installed KDE yet.

Maybe I should contact the Qt guy's for this.

Cheers,

Sohail

Did the KDE installation upgrade your Qt library? Could it be that the upgraded library does not match what Qt Designer expects? I'm not sure which distro you use, but under SuSE I believe designer is provided as part of qt-devel. Is it possible that your qt-devel is older than your qt package?
