New question #247083 on Yade:
https://answers.launchpad.net/yade/+question/247083

Hello everybody,

I've just compiled Yade-1.0.5 on my Ubuntu 64bit 12.04, I encounter this strange error: I cannot call the 3D window. (Sometimes I need to view this window when I debug my simulation)

from yade import qt
yade.qt.View()

And Yade returns Segment Core Dump then exits immediately.  I had compiled Yade-1.0.7 earlier and have the same error.
The 'cmake' and 'make'process ran very smoothly anyway, and there isn't any feature being turned off, no warning except for some error with the FLOW Engine,but it's not quite the problem here.
I did notice the warning in the installation guide [1]: **If you have Ubuntu 12.10 or older, you need to install libqglviewer-qt4-dev package instead of libqglviewer-dev.** and installed package libqglviewer-qt4-dev instead of libqglviewer-dev before compiling yade.

It's stranger when with Yade Daily installed at the same time it works like a charm. In another laptop I compiled with the same tricks with the same package and it works too, (also same ubuntu 64bit 12.04). So is this problem of YADE or a problem of the QT package? And how to fix it then?

Waiting for your help.
Thanks in advance.
