如何使用PKEY_Device_FriendlyName修复链接器错误 [英] How to fix a linker error with PKEY_Device_FriendlyName

问题描述

使用PKEY_Device_FriendlyName时，出现以下错误:

Upon using PKEY_Device_FriendlyName, I'm getting the following errors:

Error   1   error LNK2001: unresolved external symbol _PKEY_Device_FriendlyName DefaultAudioDeviceCPP.obj   
Error   2   fatal error LNK1120: 1 unresolved externals C:\Users\srobertson\Documents\Visual Studio 2005\Projects\DefaultAudioDeviceCPP\Debug\DefaultAudioDeviceCPP.exe 

清除这些错误的最简单方法是什么?我包括functiondiscovery.h和functiondiscoverykeys.h.另外，Project-> Properties ...-> Configuration Properties-> C/C ++-> General-> Additional Include Directories中的路径也是正确的.

What's a very simple way to clear these errors? I'm including functiondiscovery.h and functiondiscoverykeys.h. Also the path in Project->Properties...->Configuration Properties->C/C++->General->Additional Include Directories is correct.

有趣的是，提到的错误是:_PKEY_Device_FriendlyName，而不是PKEY_Device_FriendlyName.但是我只在程序中使用后者.

One thing of interest is that the errors are mentioning: _PKEY_Device_FriendlyName, not PKEY_Device_FriendlyName. But I'm only using the latter in my program.

推荐答案

PKEY_Device_FriendlyName驻留在uuid.lib库中.因此，您需要在源代码中添加一行:

PKEY_Device_FriendlyName resides in uuid.lib library. So you need to add a line to your source code:

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

通常，您可以与MSDN一起检查您需要引用哪个库.

Most often, you can check with MSDN which library you need to reference.
