When I tried to compile the point sprites example from opengl redbook 9th ed. using cygwin g++ and linking using -lX11 instead of windows I get an error of being unable to create context opengl 4.0-4.6. Only when I set opengl context to 3.3 does the program run and no core dump is generated. But of course I get a black window since the program needs at least opengl 4.3 to run. I'm really not sure what to do to make cygwin aware of my graphics cards capabilities?hisham... > -- maybe you need to install libGL-devel ? without further info and a simple test case we are in the dark of where is your problem.
