Hi everyone,
I've written a WebRTC client example using libwebrtc, my code works fine when I build it with libwebrtc/src/examples but I couldnt managed to run it externally.
Here are the steps I followed:
1- Build libwebrtc and obtain a static webrtc.lib file
2- Set Visual Studio to link the webrtc.lib file
3- Add additional directories:

\webrtc-checkout\src;
\webrtc-checkout\src\third_party\abseil-cpp;
\webrtc-checkout\src\third_party\jsoncpp\source\include;
4-Set preprocesssors:

5- Add webrtc.lib library directory to Linker->Additional Library Directories
5- Add webrtc.lib library directory to Linker->Additional Library Directories
6- Add additional dependencies to Linker->Input:
webrtc.lib;secur32.lib;winmm.lib;dmoguids.lib;wmcodecdspuuid.lib;msdmo.lib;Strmiids.lib;%(AdditionalDependencies)
But when I try to build, I am receiving approx 600 unresolved external symbol errors mostly realting to webrtc.lib, like rtc::SocketAddress::SetIp and etc.
What am I missing here exactly?

Hello Bertay Eren
Where did you define the .lib files of "Linker->Input", or did you copy-paste.
I'm also new to webrtc, I used to fix this error by seeing which header file the members causing the error were from.
I would then search for it in the src folder -> then open the corresponding BUILD.gn file containing that folder, and I could find the lib file containing the members causing the error.
This worked for my problem.
Please respond with your results.
