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, Laurent
