Recording, Visualizing and Persisting Data

i want to use class G4VisExecutive to visualize the examples/extended/biasing/B01, but the error occurs:

/vis/open OGL 600x600-0+0
/vis/sceneHandler/create OGL
parameter value (OGL) is not listed in the candidate List.
Candidates are: ATree DAWNFILE HepRepFile HepRepXML RayTracer VRML1FILE VRML2FILE gMocrenFile

it seems this projection can not be visualized by Qt or OpenGL driver.

did you compile geant4 with the required build option, e.g. -DGEANT4_USE_QT=ON

yes, using DGEANT4_USE_QT=on is selected.

I can use Qt driver to visualize examples/Basic/* and other projects.
