Yade

Segment Core Dump when run qt.View()

Asked by Hien Nguyen

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 (sudo apt-get install yade-daily, it was an old version). 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.

Thanks Anton,
I have no idea to say when a sources.list is messy or neat, here is mine: http://pastebin.com/MU6K80HB

Or, maybe, there is among the readers no omniscient linux consultant who can do telepathy with your hard drive and find the fix in less than two days for free?
No answer does not mean no wish to answer. :)

I am not sure, whether "ftp.free.org" server is the official
Ubuntus server. Also you have some PPAs, which can cause
package conflicts.

We will probably drop 12.04 support soon after discussing it
in yade-dev. It is too old already.

Cheers

Anton

The ftp.free.org ppa is chosen when I chose from list for France when configure the Software Update System.
In fact I tried with Synaptic and remove the conflict packages + trying to install required one from scratch, but by doing that my display of my system is totally ruined (black screen). Being furious, I formatted all and reinstalled Ubuntu + compile Yade once again, that should work.
And thanks for informing the next big update of support for Ubuntu version, I'll consider upgrading my system.
