Undefined symbols for architecture arm64 while building for iOS

[ghost]

Rebuilt libwebrtc.a, libmediasoupclient.a, libsdptransform.a according to guide, but in XCode project getting this error while trying to build. Checked paths, frameworks & libraries, but everything seems to be in place..

Undefined symbols for architecture arm64:
  "webrtc::CreatePeerConnectionFactory(rtc::Thread*, rtc::Thread*, rtc::Thread*, rtc::scoped_refptr<webrtc::AudioDeviceModule>, rtc::scoped_refptr<webrtc::AudioEncoderFactory>, rtc::scoped_refptr<webrtc::AudioDecoderFactory>, std::__1::unique_ptr<webrtc::VideoEncoderFactory, std::__1::default_delete<webrtc::VideoEncoderFactory> >, std::__1::unique_ptr<webrtc::VideoDecoderFactory, std::__1::default_delete<webrtc::VideoDecoderFactory> >, rtc::scoped_refptr<webrtc::AudioMixer>, rtc::scoped_refptr<webrtc::AudioProcessing>)", referenced from:
      mediasoupclient::PeerConnection::PeerConnection(mediasoupclient::PeerConnection::PrivateListener*, mediasoupclient::PeerConnection::Options const*) in libmediasoupclient.a(PeerConnection.cpp.o)
     (maybe you meant: webrtc::CreatePeerConnectionFactory(rtc::Thread*, rtc::Thread*, rtc::Thread*, rtc::scoped_refptr<webrtc::AudioDeviceModule>, rtc::scoped_refptr<webrtc::AudioEncoderFactory>, rtc::scoped_refptr<webrtc::AudioDecoderFactory>, std::__1::unique_ptr<webrtc::VideoEncoderFactory, std::__1::default_delete<webrtc::VideoEncoderFactory> >, std::__1::unique_ptr<webrtc::VideoDecoderFactory, std::__1::default_delete<webrtc::VideoDecoderFactory> >, rtc::scoped_refptr<webrtc::AudioMixer>, rtc::scoped_refptr<webrtc::AudioProcessing>, webrtc::AudioFrameProcessor*))
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

also getting bunch of warnings libsdptransform.a(grammar.cpp.o)) was built for newer iOS version (14.2) than being linked (10.0) on every cpp file (total 17) but i couldnt find where can i set target sdk for libsdptransform

tried

set(IPHONE_SDKVER "14.2")
set(IPHONE_VERSION_MIN "10.0")

inside mediasoup-client-ios/dependencies/CMakeLists.txt but it didnt help with libsdptransform warnings (not sure is that important or not either)

PS: Also rebuilt WebRTC.framework with use_xcode_clang = true in separate directory and put it inside out_ios_libs if that matters

Not sure is this some clang conflict or I should not have mess they deployment targets, kinda new to this but I need slightly custom webrtc build so trying to rebuild mediasoup with that

UPD: I just noticed that it is missing AudioFrameProcessor parameter at the end, so probably because of version mismatches.. Is there a way to fix it myself to latest version? Or if you just confirm that it is webrtc version mismatch i can try to update myself (if thats possible) or downgrade my webrtc sources to m84 (is that latest supported?)

What XCode version are you running? Also this will only work with webrtc branch m84, latest is not supported.

@nonpensavo Hello there. I'm experiencing exactly the same issues. Checked all the framework/library search paths. Still having undefined symbols: Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_MediasoupDevice", referenced from: objc-class-ref in ViewController.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Did you try any other steps to fix it? Any feedback would be appreciated. Thanks

Probably only occurs with newer versions of XCode?

Closing for now...
