Assertion `b->isClumpMember()' failed.

[Janek Kozicki]

After today's bzr update, I cannot anymore run scripts: funnel.py and buldozer.py

[Václav Šmilauer (eudoxos)]

Is ok here. Do you have clean source?

[Anton Gladky (gladky-anton)]

Could you not be more specific? What does not work for you?

I have found the problem only with creating video with buldozer.py

Good point, Anton. @Janek: we need backtrace.

[Janek Kozicki (cosurgi)]

ok, apparently I was caught in the middle of fixes made by Anton. Now funnel.py and buldozer.py ar working, except for the

ImportError: No module named pygst

error at the end of buldozer.py

sudo apt-get install libgts-dev

in features should be gts included (default parameter, actually)

If you mean pygts module, then you need to compile with the gts feature enabled.

features = 'gts,log4cxx,opengl,openmp,python,vtk'

it is installed already:

Checking for gts_object_class() in C++ library gts... (cached) yes

OMG can you please post backtrace or exact error message?

There is NO pygst module; perhaps pygts, and that is compiled and installed with yade.

well, my python skills are very small, so in fact I don't know if
this is the backtrace that you are looking for?

I have found this file:

~/40-Yade/Bin/HEAD-fast/lib/yade-trunk/py/gts/pygts.py

maybe yade is unable to find it? Usually I would just delete the
~/.yade-trunk dir to "refresh" whole config. But now this directory
isn't there anymore.

hm, I did a bzr update. Also, I'm sorry - I had debug=0 ! Now, with debug=1 and bzr 2193 I get this:

Do you want me to retry with debug=1 and bzr2192 and post the result?

[Václav Šmilauer (eudoxos)]

Oh, that is the backtrace. And sorry, I recalled there _is_ pygst (gstreamer); install the python-gst0.10 package. Sorry for that one. I will have a look at the clump issue. Thanks.

[Václav Šmilauer (eudoxos)]

Fixed in r2194.

[Janek Kozicki (cosurgi)]

Ok I installed python-gst0.10, now I have a following error:

It's different, so we are moving forward :)

[Janek Kozicki (cosurgi)]

I have installed gstreamer0.10-plugins-good and the encoding worked. Now I have a file /tmp/bulldozer.ogg, but this video is just one frame long. That single frame is when the calculation starts at t=0s.
