GLFW - Failed To Open A Window - opengl

Question

As my hunt for a cross-platform framework/library went in progress, GLFW was mentioned many times. So, I decided to try it out. Now, it seems as though I can't even init a window. :-/
#include
#include
#include
int main(int argc, char *argv[])
{
int running = GL_TRUE;
srand(time(NULL));
if (!glfwInit())
exit(EXIT_FAILURE);
if (!glfwOpenWindow(300, 300, 0, 0, 0, 0, 0, 0, GLFW_WINDOW))
{
glfwTerminate();
exit(EXIT_FAILURE);
}
while (running)
{
glClear(GL_COLOR_BUFFER_BIT);
glClearColor(rand() % 255 + 1, rand() % 255 + 1, rand() % 255 + 1, 0);
glfwSwapBuffers();
running = !glfwGetKey(GLFW_KEY_ESC) && glfwGetWindowParam(GLFW_OPENED);
}
glfwTerminate();
exit(EXIT_SUCCESS);
}
I typed this in MVC++ 2010, linked the header, and 2 lib files (and it had 1 DLL file, so I threw that into the SysWOW64 folder), and I get these errors:

I understand the first few with the random colors, but the ones after that make no sense to me. Any idea what's wrong with this?
I'm pretty sure that I have linked the libs correctly. I place them into the
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib directory
and even linked them to my
C:\SDK\GLFW\glfw-2.7.bin.WIN32\lib-msvc100\debug directory.
The GLFW package was a .zip file, so I just extracted it to my default SDK folder (for all my APIs and other stuff). So the C:\SDK\GLFW is my default for GLFW.

You need to link to opengl32.lib.
For that, as pictured below, go to Project Setting and then Linker > input > Additional Dependencies and add opengl32.lib there (use ; to separate different libs).
Note that you don't actually need to have opengl32.lib file anywhere. Visual Studio knows where to find it.
Edit: I should note that you don't need to do anything except adding opengl32.lib. That other stuff is irrelevant. Additionally, if both are present, try swapping the order, which matters in some cases.
