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:

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".
