Error while building .

[JojoStacy]

I have followed all the steps for building the library including building webrtc using https://github.com/crow-misia/libwebrtc-bin. Now when it comes to building libmediasoup android I get this error ld.lld: error: undefined symbol: jni_zero::JavaRef<_jobject>::JavaRef(_JNIEnv, _jobject*)

I have checked all other resources but am stuck. I need to make minor adjustments to the lib for my use case .Thank you

First, please provide a description of what you have done to do this.

Also, WebRTC versions above m124 are not supported. Therefore, even if you bring the latest version from libwebrtc-bin, you will not be able to make it work.

1. I created webrtc from bwebrtc-bin and got to download the libwertc-android.tar.xz
2. The I used it to build the libmediasoupclient using the cmake command sudo cmake . -Bbuild \ -DLIBWEBRTC_INCLUDE_PATH:PATH=/Volumes/Data/Projects/CProjects/libwebrtc-android/include \ -DLIBWEBRTC_BINARY_PATH:PATH=/Volumes/Data/Projects/CProjects/libwebrtc-android/lib \ -DMEDIASOUPCLIENT_BUILD_TESTS="true" \ -DCMAKE_CXX_FLAGS="-fvisibility=hidden" 3.I then cloned libmediasoup-android and inside deps I put both the libmediasoupclient folder and also and the libwebrtc-android unzipped and renamed webrtc. 4.I then tried to build it using cmake and that is the error that keeps coming.

Could be that am using a version of webrtc above m124 .If so how can I in ibwebrtc-bin specify a version lower than that ? Thanks so much for your initial response

[JojoStacy]

I have made changes in the VERSION file and I have put this CCACHE_VERSION=4.9 WEBRTC_VERSION=m123.6312@{#3} WEBRTC_SEMANTIC_VERSION=123.6312.3.0 WEBRTC_COMMIT=41b1493ddb5d98e9125d5cb002fd57ce76ebd8a7

PACKAGE_NAMES= \ linux-arm \ linux-arm64 \ linux-x64 \ macos-x64 \ macos-arm64 \ ios \ android

DOCKER_PACKAGE_NAMES= \ linux-arm \ linux-arm64 \ linux-x64 \ android. I am currently building. I am I on the right track ?

[crow-misia]

If you are building libwebrtc, use branch m123.6312.

1. write the version of libwebrtc in the VERSIONS of this repository. This version must match the tag name of libwebrtc-bin.

2. Run following commands to download and patch libwebrtc and libmediasoup.

   cd core/scripts/
   ./get-deps.sh

3. run ./gradlew build directly under the project to build library.

Do not run cmake directly.

noted thanks so so much ! You are the best . Trying this out!
