windows client build error

[bo__yuan]

hello,

    when I build the Open WebRTC Toolkit Native SDK, I run "python build-win.py --gn_gen --sdk --tests --ssl_root /path/to/ssl --msdk_root /path/to/msdk --output_path /path/to/out" in cmd.exe,but  the following error shows "C:\Users\MS\Desktop\owt-client-native-master\src\third_party\webrtc\logging/rtc_event_log/rtc_event_log_parser.h(158): error C2338: PacketView can only be created for standard layout types.". 

what can I do to solve this problem?

Any help&suggest would be appreciated.

Thank you.

Best Regards,

I already solved this problem by Commenting  static_assert about "is_standard_layout" in File“tc_event_log_parser.h”.
