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...

without further info and a simple test case we are in the dark of
where is your problem.
