First question is about
vtkRenderingContextOpenGL2. With 9.0.0 it seems we no longer get that library? What should I link against to pick the OpenGL2 backend for context views? Or has the library been removed and they are now using OpenGL2 by default?
Hm, now that I got the program built, it crashes at runtime with:
2020-03-22 11:51:44.120 ( 0,477s) [ F002EC40] vtkContextDevice2D.cxx:32 WARN| Error: no override found for 'vtkContextDevice2D'.
So I’m guessing there’s something missing after all. In VTK 8 I could link against vtkRenderingContextOpenGL2 to pick an implementation. What should I link against in VTK 9?
In VTK 8 I had:
