c++ - GLFW - 与 Visual Studio 2012 的链接问题

Question

我在链接 GLFW 时遇到了一个大问题。我在这个网站和其他网站上看到过多个帖子，其中已经查看了此类错误消息，但是当我尝试修复时，错误仍然存​​在。具体的错误是:

一直到错误 50，然后...

Error   51  error LNK1120: 46 unresolved externals  C:\Users\Asher\documents\visual studio 2012\Projects\Procedural Terrain\x64\Debug\Procedural Terrain.exe    Procedural Terrain

我看到这些错误并注意到末尾的“win32”。我正在使用 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 页面中描述的“未解析的外部符号”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链接了所有内容。这是我所做的。

1. 在Project>Properties>Configuration Properties>Linker>Input>Additional Dependencies下，我已经添加了GLFW.libopengl32.lib 和glu32.lib

2. 在 VC++ Directories>Include Directories 下，我添加了 C:\Users\Asher\glfw-2.7.7.bin.WIN64\glfw-2.7.7.bin.WIN64\include 。

3. 在 VC++ Directories>Library Directories 下，我添加了 C:\Users\Asher\glfw-2.7.7.bin.WIN64\glfw-2.7.7.bin.WIN64\lib-msvc110 。

我没有触及 dll，因为我更喜欢静态库。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;
}

标题包含

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

到目前为止，关于该主题的任何主题都没有任何帮助，我完全被困住了!这个问题的解决方案将不胜感激。 - Asher(从我的文件路径中可以看出 =D)

Answer 1

简要概述如果其他人偶然发现类似问题，如何调试此类问题:

首先您会注意到所有链接器错误都与 win32 库中的函数有关。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，这并没有改变任何东西，这意味着我们在链接 user32.lib 时遇到了问题。由于默认的 Visual Studio 项目不应该有这个问题，这意味着完整的安装有问题或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，但如果没有，下一步就是重新安装 Visual Studio。
