webrtc build on linux

[George Kastour]

Hi All

I'm new to webrtc , trying to build and use C++ API on Linux

I did below steps ,

mkdir webrtc-checkout
cd webrtc-checkout
fetch --nohooks webrtc
gclient sync

then using gn gen with target_os linux

then ninja -c to build

then combined all the static libraries generated after build in one static library

exported all header files of webrtc and third parties

tried an example with only one line of code, using the header files and the static library

#include "webrtc/api/peerconnectioninterface.h"

int main(int argc, char* argv[]) {

    

   

    rtc::scoped_refptr<webrtc::PeerConnectionFactoryInterface> peer_connection_factory = webrtc::CreatePeerConnectionFactory();

   

    

    return 0;

}

I got 124 errors

plz correct me, I'm sure I'm missing some stpes

Please let us know how you setup your app and how you compiled it to link with the libraries. 

I think you should only need to link with out/Debug/obj/webrtc/libwebrtc.a in order to get it to run - it is a fat library that contains everything.

Hi Henrik 

Thanks for your reply, I linked against the fat libwebrtc.a, tried it on mac OSX and it worked perfect, 

now I'm trying to do the same for IOS , so I fetched webrtc-ios and built it for arm , according to the device I'm testing on, when I link against libwebrtc.a , I get link error
