I trying to deal with the AppRTCDemo projet but I am getting error. Which library I forget to include ?

Log error :

Undefined symbols for architecture armv7s: "_OBJC_CLASS_$_RTCVideoRenderer", referenced from: objc-class-ref in VideoView.o "_OBJC_CLASS_$_RTCSessionDescription", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_RTCICECandidate", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_RTCVideoCapturer", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_RTCPair", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_RTCMediaConstraints", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_RTCPeerConnectionFactory", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_RTCICEServer", referenced from: objc-class-ref in APPRTCAppClient.o ld: symbol(s) not found for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation)

Thanks

The solution is to set the "Other Linker Flags" in the build setting of your project to $(inherited).

Then it will be an inherited link options from the workspace.

Maybe this library isn't built for armv7s processors.

Is it static lib built in .a file?

If so, you can run in console lipo -info command to see what architectures is this library built for.

For example, this command for some library somelib.a lipo -info somelib.a gives output:

Architectures in the fat file: somelib.a are: armv7 i386

If armv7s architecture isn't supported, but armv7 is, you can also run your project, try setting this in your build options:

"Build Active Architecture Only" YES --> NO.

You may be testing on iPhone 5 or above which is on armv7s architecture (see http://iossupportmatrix.com/ for more info).

The AppRTCDemo was built on armv7, that assume to run it on devices issued between the iPhone 3GS and the iPad mini (that includes iPhone 4 and 4s).
