Glut Camera/stray error: need tutorial/advice
Hello, I am new to C++ and Glut (I know some C), and I have made an attempt to add a camera to a basic Glut program. However, when I compile, I get these following errors:

Could you let me know what I am doing wrong, and/or reccomend a glut camera tutorial? Thanks!!!!!
