Comment 1 garnier 2010-07-29 17:19:37 CEST

This problem could occurs with 
- OpenGL AND MacOsX snow leopard (and after) versions.
- All Geant4 versions

 The fact is it does not link with correct OpenGL libraries.

You have to change *one* line in /config/sys/Darwin-g++.gmk file :
- Go in "config/sys/Darwin-g++.gmk
- around line 60, you will find :

_____________________________
ifndef OGLLIBS
  ifeq ($(shell uname -r | sed 's/\([0-9]*\).[0-9]*.[0-9]*/\1/'),9)
    # the following lines are for building on MacOSX 10.5 "Leopard"
    OGLLIBS   := $(shell test -f /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib && echo "-L/usr/X11R6/lib -lGLU -lGL -Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib")
  else
    OGLLIBS   := -L$(OGLHOME)/lib -lGLU -lGL    <-----LINE TO MODIFY !!!!
  endif
endif
_____________________________

- change the line :
    OGLLIBS   := -L$(OGLHOME)/lib -lGLU -lGL    <-----LINE TO MODIFY !!!!
By :
     OGLLIBS   := -F/System/Library/Frameworks/ -framework OpenGL -framework AGL

- go in /source/visualization/OpenGL;
- make clean; make
- go in your prog folder
- make clean; make

Thanks,
