Hello. I’m trying to make android client support myself with latest libmediasoupclient. I’m stuck at building libmediasoupclient. First I build webrtc from branch-heads/4147 branch With ```auto gn gen out/Release --args='is_debug=false is_component_build=false rtc_include_tests=false target_os="android" target_cpu="arm" is_clang=false rtc_use_h264=true use_rtti=true use_custom_libcxx=false treat_warnings_as_errors=false use_ozone=true' ``` And then, when I try to build libmediasoupclient with: ```auto cmake . -Bbuild \ -DLIBWEBRTC_INCLUDE_PATH:PATH=$HOME/webrtc/src \ -DLIBWEBRTC_BINARY_PATH:PATH=$HOME/webrtc/src/out/Release/obj \ -DCMAKE_CXX_FLAGS="-fvisibility=hidden" ``` I’m getting this error: ```auto make: Entering directory '/home/mikluha/Projects/libmediasoupclient/build' make[1]: Entering directory '/home/mikluha/Projects/libmediasoupclient/build' make[2]: Entering directory '/home/mikluha/Projects/libmediasoupclient/build' Consolidate compiler generated dependencies of target sdptransform make[2]: Leaving directory '/home/mikluha/Projects/libmediasoupclient/build' [16%] Built target sdptransform make[2]: Entering directory '/home/mikluha/Projects/libmediasoupclient/build' Consolidate compiler generated dependencies of target mediasoupclient make[2]: Leaving directory '/home/mikluha/Projects/libmediasoupclient/build' make[2]: Entering directory '/home/mikluha/Projects/libmediasoupclient/build' [20%] Building CXX object CMakeFiles/mediasoupclient.dir/src/Consumer.cpp.o [24%] Building CXX object CMakeFiles/mediasoupclient.dir/src/DataConsumer.cpp.o [28%] Building CXX object CMakeFiles/mediasoupclient.dir/src/DataProducer.cpp.o [32%] Building CXX object CMakeFiles/mediasoupclient.dir/src/Device.cpp.o [36%] Building CXX object CMakeFiles/mediasoupclient.dir/src/Handler.cpp.o [40%] Building CXX object CMakeFiles/mediasoupclient.dir/src/PeerConnection.cpp.o [44%] Building CXX object CMakeFiles/mediasoupclient.dir/src/Producer.cpp.o [48%] Building CXX object CMakeFiles/mediasoupclient.dir/src/Transport.cpp.o [52%] Building CXX object CMakeFiles/mediasoupclient.dir/src/mediasoupclient.cpp.o [56%] Building CXX object CMakeFiles/mediasoupclient.dir/src/ortc.cpp.o /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp: In function ‘bool matchCodecs(json&, json&, bool, bool)’: /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1603:39: error: ‘CodecParameterMap’ is not a member of ‘webrtc::H264’ 1603 | webrtc::H264::CodecParameterMap aParameters; | ^ ~~~~~~~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1604:39: error: ‘CodecParameterMap’ is not a member of ‘webrtc::H264’ 1604 | webrtc::H264::CodecParameterMap bParameters; | ^ ~~~~~~~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1606:25: error: ‘aParameters’ was not declared in this scope 1606 | aParameters["level-asymmetry-allowed"] = std::to_string(getH264LevelAssimetryAllowed(aCodec)); | ^ ~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1609:25: error: ‘bParameters’ was not declared in this scope 1609 | bParameters["level-asymmetry-allowed"] = std::to_string(getH264LevelAssimetryAllowed(bCodec)); | ^ ~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1616:39: error: ‘CodecParameterMap’ is not a member of ‘webrtc::H264’ 1616 | webrtc::H264::CodecParameterMap newParameters; | ^ ~~~~~~~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1620:47: error: ‘GenerateProfileLevelIdForAnswer’ is not a member of ‘webrtc::H264’ 1620 | webrtc::H264::GenerateProfileLevelIdForAnswer(aParameters, bParameters, &newParameters); | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1620:106: error: ‘newParameters’ was not declared in this scope 1620 | webrtc::H264::GenerateProfileLevelIdForAnswer(aParameters, bParameters, &newParameters); | ^ ~~~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1622:37: warning: catching polymorphic type ‘class std::runtime_error’ by value [-Wcatch-value=] 1622 | catch (std::runtime_error) | ^ ~~~~~~~~~~~~ /home/mikluha/Projects/libmediasoupclient/src/ortc.cpp:1629:57: error: ‘newParameters’ was not declared in this scope 1629 | auto profileLevelIdIt = newParameters.find("profile-level-id"); | ^ ~~~~~~~~~~~~ make[2]: *** [CMakeFiles/mediasoupclient.dir/build.make:216: CMakeFiles/mediasoupclient.dir/src/ortc.cpp.o] Error 1 make[2]: Leaving directory '/home/mikluha/Projects/libmediasoupclient/build' make[1]: *** [CMakeFiles/Makefile2:135: CMakeFiles/mediasoupclient.dir/all] Error 2 make[1]: Leaving directory '/home/mikluha/Projects/libmediasoupclient/build' make: *** [Makefile:136: all] Error 2 make: Leaving directory '/home/mikluha/Projects/libmediasoupclient/build' ``` And ```auto ./tools_webrtc/android/build_aar.py --extra-gn-args 'is_debug=false is_component_build=false is_clang=true rtc_include_tests=false rtc_use_h264=true rtc_enable_protobuf=false use_rtti=true use_custom_libcxx=false' --build-dir ./out/release-build/ ``` doesn’t make .a files, so I use gn gen Thanks for any help! I had to mention I also get a lot of warning when building webrtc, similar to ```auto warning: unknown warning option '-Wno-class-memaccess'; did you mean '-Wno-class-varargs'? [-Wunknown-warning-option] ``` when I build with is\_clang=false UPD: I did everything from start and it worked, don’t know why. Sorry for bumping ---

> [@MikluhaMaclay](#): > > `CodecParameterMap’ is not a member of ‘webrtc::H264’` It’s defined in `media/base/h264_profile_level_id.h` in webrtc sources. It should be accessible.
