GLFW -与Visual 2012链接的问题

Question

我遇到了一个连接GLFW的大问题。我在这个网站和其他网站上看到了很多这样的错误信息，但是当我尝试修复时，错误仍然是一样的。具体的错误是：

一直到错误50然后..。

我看到了这些错误，并注意到最后的"win32“。我使用64位系统、64位项目(由解决方案平台声明)和GLFW的64位二进制下载。GLFW FAQ页面描述的“未解决的外部符号”的错误表明，链接问题是造成这种情况的原因。但是，我相信我已经为静态库正确地连接了所有的东西。这就是我所做的。

1. 在Project>Properties>Configuration Properties>Linker>Input>Additional依赖项下，我添加了GLFW.lib opengl32.lib和glu32.lib
2. 在VC++ Directories>Include目录下，我添加了Directories>Include。
3. 在VC++ Directories>Library目录下，我添加了Directories>Library。

我没有接触dll，因为我希望使用静态库。另外，这是我的代码

#include "Header.h"

using namespace std;
int main(int argc, char **argv){
//Initializes non-window dependent sources.
 if (!glfwInit())
{
    cout<< "Failed to initialize GLFW";
    return -1;
}
 //Sets window parameters
glfwOpenWindow(0, 0, 0, 0, 0,
           0, 8, 0, GLFW_FULLSCREEN);
//Window name
glfwSetWindowTitle("The GLFW Window");
//Terminates GLFW.
glfwTerminate();
return 0;
}

标头包含

#include <IOstream>
#include <GL\glfw.h>

到目前为止，这个问题还没有得到任何帮助，我被困住了！如果能解决这个问题，我们将不胜感激。- Asher (从我的文件路径中可以看出=D)

如果其他人遇到了类似的问题，那么如何调试这样的问题：

首先，您将注意到，所有链接器错误都引用了win32库中的函数。因此，我们首先尝试直接调用其中一个函数，看看它是否改变了什么。

正如预期的那样，这并没有改变任何事情，这意味着我们在链接user32.lib时遇到了问题。因为默认的Visual项目不应该有这个问题，这要么意味着完整的安装有问题，要么只有特定的解决方案。创建一个新的解决方案解决了这个问题，但如果不是的话，下一步将是重新安装Visual。
