[Janek Kozicki <janek_listy@xxxxx>]

Now after svn update. SVN-HEAD. I tried to play with python
So here's my session (crashed at the end):

The program is running.  Quit anyway (and detach it)? (y or n) y




But I think I made it work with >>> p.generator="SDECSpheresPlane"
The simulation was running, only things that didn't work was:

>>> v=View()

Opened a view, but with unrefreshable remnants of QTFileGenerator
inside (the same that we see in QtGUI). Maybe it was simply in that
part of memory, not something that current session created. And lots
of errors:

QGLContext::makeCurrent(): Failed.

I remember this error. We had it, and yade was frequently crashing.
Olivier's laptop was hanging sometimes. And later I've found some
solution for that and it works cleanly now. I forgot what it was....
gotta look into SVN history for that.

I remember you talking something about pyView() so I tried:

>>> v=pyView()
Traceback (most recent call last):
  File "<console>", line 1, in ?
NameError: name 'pyView' is not defined

But nothing,

And finally - crash at exit:



>>> QGLContext::makeCurrent(): Failed.
sys.exit(0)

Looks like gdb tried to start, but failed: ptrace: No such process. I
hope that you can distinguish copy/pastes from my comments ;-)
