In the solution explorer, right-click your project and select properties. From the configuration list box, select "all configurations". In the left pane, select the Linker sub-tree and then the input option. Add opengl32.lib under "Additional Dependencies".

I'm using VC++ 2010 to work with some OpenGL. However, it's becoming a pain. I keep getting error codes again and again.

Here is the code I am working with:

// Include standard headers
#include <stdio.h>
#include <stdlib.h>


// Include GLEW
#include <GL/glew.h>

// Include GLFW
#include <GL/glfw.h>


// Include GLM
#include <glm/glm.hpp>
using namespace glm;
int main( void ){        
    // Initialise GLFW
    if( !glfwInit() ){

            fprintf( stderr, "Failed to initialize GLFW\n" );
            return -1;
    }

    glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4);
    glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
    glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
    glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    // Open a window and create its OpenGL context
    if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )
    {
            fprintf( stderr, "Failed to open GLFW window. If you have an Intel GPU, they are not 3.3 compatible. Try the 2.1 version of the tutorials.\n" );
            glfwTerminate();
            return -1;
    }

    // Initialize GLEW
    if (glewInit() != GLEW_OK) {
            fprintf(stderr, "Failed to initialize GLEW\n");
            return -1;
    }

    glfwSetWindowTitle( "Tutorial 01" );

    // Ensure we can capture the escape key being pressed below
    glfwEnable( GLFW_STICKY_KEYS );

    // Dark blue background
    glClearColor(0.0f, 0.0f, 0.3f, 0.0f);

    do{
         // Draw nothing, see you in tutorial 2 !

         // Swap buffers
         glfwSwapBuffers();

    } // Check if the ESC key was pressed or the window was closed
    while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
         glfwGetWindowParam( GLFW_OPENED ) );

// Close OpenGL window and terminate GLFW
    glfwTerminate();
    return 0;
}

Here are the errors I am getting from Visual Studio after compiling the code above. The output appears to be linking issues, however, I'm not sure how to correctly link the glfw requirements with the editor. Example errors:

@NathanHatch-Martinez: For the LNK1120 error, please see this link. For the LNK2019, I recommend this link.

Ok, side note: I used the wrong libs... Thank you for your help.
