While attempting to incorporate shaders for PPL, i think i accidently removed a few includes and now my program wont run even with commenting out all the glsl code and reverting back to my original program.
The errors:
1>main.obj : error LNK2019: unresolved external symbol [email="__imp__glutSwapBuffers@0"]__imp__glutSwapBuffers@0[/email] referenced in function "void __cdecl drawScene(void)" ([email="?drawScene@@YAXXZ"]?drawScene@@YAXXZ[/email])

They appear to be glut errors, but beyond that im not sure.
I tried to backtrack and figure what i did wrong. So i'll name off the things i currently have in my program and whether or not i changed them while trying to get my shader to work.
Includes: (I did remove 1 or 2 that may have caused these errors)
C:\Users\Shawn\Documents\New folder\First Project - visual\Light\Light\glew\include
C:\Users\Shawn\Documents\New folder\First Project - visual\Light\Light\cwc\include
C:\Users\Shawn\Documents\New folder\First Project - visual\Light\Light\freeglut\include
C:\Program Files %28x86%29\Microsoft Visual Studio 10.0\VC\include
Linkers:(Never touched)
SOIL.lib glu32.lib opengl32.lib
And the includes in my program:
#include <stdlib.h>
#include <gl/glut.h>
#include <SOIL.h>
#include <string>
#include <iostream>
I would greatly appreciate help!

Seems, that you miss linking against glut32.lib.
