I'm working on an OpenGL app, and when I use >gcc -mwindows code.C -lopengl32 -lglu32 I get an executable that runs fine. However, when I use >gcc -mno-cygwin -mwindows code.C -lopengl32 -lglu32 I get >code.C:17 gl/gl.h: No such file or directory >code.C:18 gl/glu.h: No such file or directory and the compile fails. I also tried >gcc -mno-cygwin -mwindows code.C -I /usr/include -lopengl32 -lglu32 but I get warnings about APIENTRY being redefined. However, the executable seems to work. Can anyone help me understand what's going on here? Shawn -- Want to unsubscribe from this list? Check out: http://cygwin.com/ml/#unsubscribe-simple
