How to fix a linker error with PKEY_Device_FriendlyName

Question

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

Error   1   error LNK2001: unresolved external symbol _PKEY_Device_FriendlyName Defau         


        

Answer 1

An updated solution that worked for me, as per the microsoft docs

#include <functiondiscoverykeys.h>

Answer 2

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

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

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

Answer 3

Old post, but hopefully this answer will save someone some time.

I was having the same problem with DEVPKEY properties - like DEVPKEY_Device_FriendlyName. I got a very similar link error. I stumbled upon the answer in comments here: Referencing GUIDs

Basically, add an #include before the include for things like devpkey.h where the property keys are defined.

So, at the top of my file I have:

#include <setupapi.h>  
#include <initguid.h>  // Put this in to get rid of linker errors.  
#include <devpkey.h>  // Property keys defined here are now defined inline.
