链接:致命错误 LNK1561:必须在 VC++ 中定义入口点错误

I installed MS VS VC++ for the first time in order to start programming OpenGL with GLFW library. I follower instructions on how to install it over at http://shawndeprey.blogspot.com/2012/02/setting-up-glfw-in-visual-studio-2010.html Then I wrote this simple program, just to test it, which did work on Eclipse:

#include <stdlib.h>
#include <GL/glfw.h>

using namespace std;

int main()
{
    int running = GL_TRUE;
    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 );
        glfwSwapBuffers();
        running = !glfwGetKey(GLFW_KEY_ESC) && glfwGetWindowParam(GLFW_OPENED);
    }

    glfwTerminate();
    exit(EXIT_SUCCESS);
    return 0;
}

但后来我得到了这个可怕的错误:
