Warning: It's a while since I did this. ;-) Some graphics modes and/or graphics cards are unsupported, so mgl will not work in some situations. The demo programs do not make full use of error codes (or this information is not available, IIRC the function QuickInit() is a culprit) so that is why they just quietly return without doing anything. What graphics card do you have and what version of the library are you using? That information will be useful to anyone trying to help. > am i supposed to set the graphics mode myself or something? Possibly you could fiddle with the demo code to try and figure out what is failing. It would be a good idea to try your compiled binaries on a machine with a different graphics card to confirm this as the problem. You could also try an older or newer version of the library to see if it better supports your graphics card / mode (if that is the problem). Scitech also host mgl newsgroups on their news server, see the web site for details.
