Are you sure that's the repository your packages are coming from? It's discontinued and to me it looks rather empty: http://build.openmodelica.org/apt/dists … 6/Packages (some other packages are left)

Are you using deb-src or some other repo?

apt-cache show omc | grep ^Filename:

thank you for the hint. Hmm I believe it worked 2 week ago .. .
Anyway I changed it  to

deb   http://build.openmodelica.org/apt squeeze nightly

and got an update to Version: 15923-1.

unfortunately the problem remains the same. Do you think
I should compile everything from source?


$ apt-cache show omc

I have a wheezy repository in the pipeline. Let's say 4 or 5 hours from now you will be able to use wheezy nightly if everything works out fine. Hopefully that will solve it. Else, "raring" (2013) or "quantal" (2012) probably work better than squeeze (2011). I would really like for wheezy to be released soon so I can stop supporting squeeze.

Ok, wheezy is up. Of course there were problems

Thanks a lot. I  installed all packages from the new repository and
everything is up to date

apt-cache show omc | grep ^Filename:

    Filename: pool/contrib-wheezy/omedit_15947-1_i386.deb

Unfortunately the problem still remains. I tried again:

Mechanics.Rotational.Examples.First:

  After the simulation run I have to wait approx 5 minutes. Then CPU load went down and
  I could use the plotting view. After switching to modeling view and  back to plotting 
OMEdit was frozen agein.

  similar (but not exactly reproducable) results happen with other examples (Blocks.Examples.PID_Controler)

Next I would like to test OMEdit on a fresh installed Ubuntu distribution.

Do you have suggestions how to  track down the problem?

Meanwhile I terminate OMEdit after the simulation run, read the mat file
with octave and do plotting from there.

Thank you for your help

OK. Subscribe to the follow bug report https://trac.openmodelica.org/OpenModelica/ticket/2145. I think it's related and possibly a reason why wheezy was not released yet. Although more likely is OMEdit does something bad (it often does).

I just want to mention my latest experience.

The problem seems related to Debian Wheezy and KDE. If I use another Desktop Environment
( I tried icewm) the problem vanished and OMEdit works like a charme.

Starting a fresh KDE Desktop environment for an new created user will not solve
the problem.

Also the experiment to copy the OMEdit executable together
with all shared libraries from a Ubuntu 12.04 system to my Debian box, didn't
help.

I wonder if OMEdit is working on a Kubuntu system. Maybe somebody else can try ..

For now I have found a workaround and I can concentrate my work
on developping Modelica Simulation models.
