OpenGL with Qt4 crashes, but not standard OpenGL
Message 1 in thread
Hi,
I have a concern with Qt 4 and Fedora Core 5. I'm porting an
application from GLUT to Qt4, and the program that runs fine on Windows
crashes with Linux in libGLCore from nVidia. Furthermore, none of the
Qt4 examples runs, they all crash - Segmentation Fault -. The intriguing
part is that with GLUT, the program did not crash !
I don't know if this is really a Qt4 problem or a configuration problem,
but as the crashs occur only with Qt... Can it be that the Qt4 openGL
library must be compiled on my box ?

Or an nVidia bug.

In particular, can you duplicate the problem when *not* using the
closed-source/binary nVidia driver?

Not for the moment as I have to wait for several tests to complete, and
each takes some days to end... But I'll certainly try as soon as I can !

Have you used any soft compiled by hand? I mean, not packaged for your distro?

Sorry, I meant that the problem should be in the setup of your
machine's soft, and (possibly) not in the video card's driver. Please,
take no offense, I'm not an english native speaker (I'm from
argentina). Et mon francais c'est horrible ;-)

No, everything is pre-packaged, I only use a nVidia driver not present
on the official repository, but on fedoracorefaq :(

I didn't take any offense, I know with your answer that you have not
that peculiar problem, so it should be on my side ;) I'll have to ckeck
one way or another...
