Without visualization everything seems to work fine. I have tried following to get a СcorrectТ openGL.   Yum install on mesa-libGL Цdevel and mesa-libGLU Цdevel. Getting MesaGLUT-6.5 and MesaLib-6.5 and doing the make (puutinn the result in a different directory to X11R^ and then setting the path to the new value in the configure part.   In both case I get the following error messages from the Geant install:   **************************************************************************************************** Compiling G4OpenGLImmediateSceneHandler.cc ...
