I compiled and ran the program in a mintty window, while X server was started and the environment variable DISPLAY was set. It ran perfectly. I don't have XTerm installed, it would probably have taken care of the DISPLAY variable. I started a second mintty window and started the program from there without setting DISPLAY, and the program complained "cannot connect to X server". I think Rafał started the program from a shell which had DISPLAY set, but @Rafał if you could confirm that it would help a bit. I think some Cygwin X components may be missing. The reason I think this is the message that says the Windows DRI extension is missing, which I guess is awfully specific. It occurs to me that starting XTerm would be a useful diagnostic, but if "Windows DRI" is missing, XServer probably can't start, never mind "Windows DRI extension" -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
