Created attachment 399 [details]
fallback handling stubbed out via "#ifdef STUB_TJR"

On Mac OS X 10.9.5 (Mavericks), geant4.10.02.p01, the OpenInventor driver builds OK. My program links OK.

When executed, I get this error:
/vis/open OIX
ERROR: G4VisCommandSceneHandlerCreate::SetNewValue: could not find fallback graphics system for "OIX".
ERROR: G4VisCommandViewerCreate::SetNewValue: no scene handlers.

The fallback logic is obscure, so I edited G4VisCommandSceneHandlerCreate.cc to omit the fallback handling (attached), and it now works OK.

I believe this also applies to geant4.10.02.
This probably applies to other hardware and OSs.

  is not built.
