Is it possible to compile programs using GLX under cygwin? I am trying to compile the attached example with command
g++ -I/usr/X11R6/include -L/usr/X11R6/lib -lX11 -lGL glxsample.cpp -o glxsample
All the X and glx functions are reported undefined. Am I doing something wrong? I've found the thread in [EMAIL PROTECTED] list about OpenGL but that was about linking to the hw accelerated libs. I need to compile program written for the glx. Thanks.
