[vtkusers] vtk6 porting question (segfault)

Tue Aug 14 16:37:03 EDT 2012

OK, I was able to build all of the examples OK.

My problem is that I do not use CMake in my application, so relying on
CMake is not a very good solution for me. Are there any resources for how
to write portable applications using VTK 6.0, I have been relying on users
to have VTK installed already. Maybe I should stick with 5.10 for a while.

Thanks again,

-- Trevor
