[vtkusers] core dump with vtk4.0/python on Linux

Thu Apr 4 22:37:34 EST 2002

Hi jon,
   I had already done a 'make clean' and rebuild with g++ instead of c++
and
now I don't have anymore this problem (it's obviously not related, but I
really don't know what was wrong).
But I have now a problem with vtkTkRenderWidget.py

I went on vtk website download the nightly source, rebuilt from scratch.
Then I went into VTK/Wrapping/Python
and try:
python vtkRenderWidget.py

..But I get a core dump.

Here is what I have with gdb :

And here is a part of my .cshrc file:
setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH":/shalom/data/mmalat/VTK/bin/"
setenv PYTHONPATH
/shalom/data/mmalat/VTK/Wrapping/Python:/shalom/data/mmalat/VTK/bin

I really don't know what I did wrong. Any idea would be really helpfull
Mathieu
Ps: It is related only to Python because tcl work fine.
