I’m trying to compile libmediasoupclient C++ client sdk with lastest libwebrtc: CMakeLists.txt: ```auto # Project configuration. set(LIBWEBRTC_INCLUDE_PATH "/Users/chenzx/repo/webrtc/src/" CACHE STRING "libwebrtc include path") set(LIBWEBRTC_BINARY_PATH "/Users/chenzx/repo/webrtc/src/out/Debug/obj/" CACHE STRING "libwebrtc binary path") ``` But compiles error: ```auto [60%] Building CXX object CMakeFiles/mediasoupclient.dir/src/ortc.cpp.o /Users/banma-0643/repo/webrtc_server_demo/libmediasoupclient/src/ortc.cpp:1603:18: error: no type named 'CodecParameterMap' in namespace 'webrtc::H264' webrtc::H264::CodecParameterMap aParameters; ~~~~~~~~~~~~~~ ^ /Users/banma-0643/repo/webrtc_server_demo/libmediasoupclient/src/ortc.cpp:1604:36: error: use of undeclared identifier 'bParameters'; did you mean 'aParameters'? webrtc::H264::CodecParameterMap bParameters; ^ ~~~~~~~~~~ aParameters ``` It seems latest libwebrtc source code removed `webrtc::H264` related code? How can i switch libwebrtc’s version to mediasoup-compliant M74? ---

We write documentation for something. ---

I’m using Mac 10.15, and: ```auto src % ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ DriverKit20.2.sdk MacOSX.sdk MacOSX11.1.sdk ``` i guess the m84 build script is not robust enough ---

I’m afraid that is a pure libwebrtc issue. We cannot give support about libwebrtc. Maybe others can. ---

I fixed this, i changed src/build/mac/find\_sdk.py to adapt to new version sdk: line: ```auto sdks = [re.findall('^MacOSX(10\.\d+)\.sdk$', s) for s in os.listdir(sdk_dir)] ``` changed to ```auto sdks = [re.findall('^MacOSX([0-9]{2}\.\d+)\.sdk$', s) for s in os.listdir(sdk_dir)] ```
