LNK2019 can't resolve

Question

Before I post the question, I have read the following document.

I am programming a VoIP client with Qt and one of PJProject/LinphoneSDK (I have tried both of them) by the VS2019 Community and Qt Creator. But commonly use MSVC2019. It always get the error LNK2019 whatever library and code I put in. Can someone provide a solution?

Project configuration->VC++ Directories->Include Directories/Libraries has been config correctly.

Answer 1

Probably you did not set some parameters, such as Linker -> Additional Dependencies, for all of configurations (which are displayed in dropdown lists of Project Properties.

If you know which library files (.lib) should be added, you can also insert #pragma lines to any file, for example:

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

Check if the product’s documentation contains detailed instructions.
