I think the proper links have been made to the needed files. I can compile the examples are run them just fine. I again tried copying the example from chapter 2 word for word and file for file, and I get this error as well. ....Perhaps my gl.h include file is old? Actually it can't be, because the examples compile fine. I am using the WinMain from the book, "Beginning OpenGL Programming" and I will add it at the end here as well. To be specific to only difference is the class name that I use instead of what the book uses. I have killed too many hours comparing and trying to figure this out, I know what the errors mean but not why they are happening. Feels like I have just started programming, but I have been going it for years.
