[vtkusers] vtk6 porting question (segfault)

Tue Aug 14 15:41:51 EDT 2012

Thanks for the help. I think it's come down to not having VTK_USE_RENDERING
defined.
At least I get this error when following the directions on
http://vtk.org/Wiki/VTK/Examples/Cxx.

However, this does not seem to be an option when configuring VTK. There is
VTK_Group_Rendering, but no VTK_USE_RENDERING option.

I also find this strange, as in my installation directory
 $ ls -l  libvtkRendering*.so

libvtkRenderingAnnotation-6.0.so
libvtkRenderingGL2PS-6.0.so
libvtkRenderingMathText-6.0.so
libvtkRenderingAnnotationPython27D-6.0.so
libvtkRenderingGL2PSPython27D-6.0.so
libvtkRenderingMathTextPython27D-6.0.so
libvtkRenderingContext2D-6.0.so
libvtkRenderingHybridOpenGL-6.0.so           libvtkRenderingOpenGL-6.0.so
libvtkRenderingContext2DPython27D-6.0.so
libvtkRenderingHybridOpenGLPython27D-6.0.so
libvtkRenderingOpenGLPython27D-6.0.so
libvtkRenderingCore-6.0.so
libvtkRenderingImage-6.0.so
libvtkRenderingVolume-6.0.so
libvtkRenderingCorePython27D-6.0.so
libvtkRenderingImagePython27D-6.0.so
libvtkRenderingVolumeOpenGL-6.0.so
libvtkRenderingFreeType-6.0.so
libvtkRenderingLOD-6.0.so
libvtkRenderingVolumeOpenGLPython27D-6.0.so
libvtkRenderingFreeTypeOpenGL-6.0.so
libvtkRenderingLODPython27D-6.0.so
libvtkRenderingVolumePython27D-6.0.so
libvtkRenderingFreeTypeOpenGLPython27D-6.0.so
libvtkRenderingLabel-6.0.so

libvtkRenderingFreeTypePython27D-6.0.so
libvtkRenderingLabelPython27D-6.0.so

Generates quite a lot of hits. Thanks again for the tips and suggestions.
