无法解析的外部符号_IID_IDXGIFactory [英] Unresolved external symbol _IID_IDXGIFactory

问题描述

我在VC ++ 2010中创建控制台应用程序，并向其中添加以下代码:

I create Console Application in VC++ 2010, and add the following code to it:

#include <d3d10.h>
#include <d3dx10.h>
#include <DxErr.h>

#pragma comment(lib, "d3d10.lib")
#pragma comment(lib, "d3dx10.lib")
#pragma comment(lib, "dxgi.lib")
#pragma comment(lib, "dxerr.lib")

int _tmain(int argc, _TCHAR* argv[])
{
    IDXGIFactory* pDXGIFactory;
    CreateDXGIFactory(IID_IDXGIFactory, ( void** )&pDXGIFactory);

    return 0;
}

正在构建此项目，我有链接器错误:错误LNK2001:无法解析的外部符号_IID_IDXGIFactory

Building this project, I have linker error: error LNK2001: unresolved external symbol _IID_IDXGIFactory

现在，我创建具有MFC支持的控制台应用程序，并添加相同的代码.构建成功.第一种情况有什么问题?为什么MFC项目建立成功，非MFC项目失败?

Now I create Console Application with MFC support, and add the same code. The build is successful. What is wrong in the first case? Why MFC project is built successfully, and non-MFC project fails?

推荐答案

您需要引用另一个包含此标识符的库:

You need to reference another library, which holds this identifier:

#pragma comment(lib, "windowscodecs.lib")

MSDN说，其 DXGI.lib ，但实际上至少Windows SDK 7.0在不同的库中具有它.

MSDN says its DXGI.lib but effectively at least Windows SDK 7.0 has it in a different library.
