hard crash on vtk 8

Support
1

We currently have an app that runs on vtk 6.3, using Java, and we’re working on getting things to run on 8.1.2. We’ve built the new libs, and updated DYLD_LIBRARY_PATHs accordingly to point to the new jnilibs.

I’m getting a fatal error from a deg fault that is dumping info to a hs_err file (I would attach it but I am too new to the discourse to do so). The top of the stack in that file is:

j vtk.vtkGenericOpenGLRenderWindow.Render_31()V+0
j vtk.vtkGenericOpenGLRenderWindow.Render()V+1
j vtk.rendering.jogl.vtkAbstractJoglComponent$1.display(Lcom/jogamp/opengl/GLAutoDrawable;)V+16
j jogamp.opengl.GLDrawableHelper.displayImpl(Lcom/jogamp/opengl/GLAutoDrawable;)V+62
j jogamp.opengl.GLDrawableHelper.display(Lcom/jogamp/opengl/GLAutoDrawable;)V+2
j com.jogamp.opengl.awt.GLJPanel$Updater.display(Lcom/jogamp/opengl/GLAutoDrawable;)V+200

Which to me looks like a JNI problem, but I’m not sure. Any thoughts on this? We’d really like to modernize our app, and this is a major hurdle. Thanks!

To make sure it is not a build issue of VTK, can you reach out to me privately so I can share a VTK build for macOS so you can try it out?

Best way to do that?

OK, so it looks like the prebuilt libs seemed to get past my problems. Now I’m working on making sure I can build them myself.

My one concern is that the vtk-superbuild project only refers to a max of VTK7 (the BUILD_VTK7 flag, for example) - if that flag is set it will use OpenGL2, otherwise it uses OpenGL. I’m going to run it with that flag set to true (even though I am building VTK8.2), but that flag should probably be renamed if it is valid for anything > VTK 7. I’ll report back here when I know more.
