Open GL compilation error #81

Open YonatanSimson opened 7 years ago

YonatanSimson commented 7 years ago

In order to get the example from chapter 3 to compile one should replace

include <gl/gl.h>

include <gl/glu.h>

with:

include <GL/gl.h>

include <GL/glu.h>

You should compile OpenCV source codes with OpenGL support and then use it. That's it! You can use CMake for compiling OpenCV with OpenGL support on Windows platform.

I ran into many GL header related errors using Visusal Studio 2019.

The solution in my case was to simply: #include <windows.h> before GL.
