Troubleshooting
Segmentation fault in Ubuntu 11.10
If the reconstructor crashes like that (numbers can vary):
$ ./3dbar.sh ./3dbar.sh: line 17: 2296 Segmentation fault python bin/reconstructor/gui.py
the reason can be a bug in the 'python-vtk' package installed in your system. Unfortunately there is no automated way to fix it - you have to do it manually:
- Find a file named 'wxVTKRenderWindowInteractor.py'. It can be located in '/usr/share/pyshared/vtk/wx/' directory or in similar location:
$ find / -name 'wxVTKRenderWindowInteractor.py'
- Edit the file with your favourite ASCII editor. In the example editor 'vim' is used and it is assumed that the path to the file is '/usr/share/pyshared/vtk/wx/wxVTKRenderWindowInteractor.py':
$ sudo vim /usr/share/pyshared/vtk/wx/wxVTKRenderWindowInteractor.py
- Near 350th line of the file find a following line:
d = '_%s_%s' % (d[2:], 'void_p')
- Add '\0' characters to the line to make it like below:
d = '_%s_%s\0' % (d[2:], 'void_p')
- Save the modified file.
- The bug should be fixed for now. Try running 3dBAR again. If this solution doesn't work - let us know.
