1. 问题：

1.1 LNK2038 检测到“_ITERATOR_DEBUG_LEVEL”的不匹配项: 值“0”不匹配值“2”(RTCRoomImpl.obj 中) XWRtc D:\XWRTC\client\windows\XWRtcWinDemo\XWRtc\libcpmtd0.lib(xgetwctype.obj) 1

_ITERATOR_DEBUG_LEVEL不匹配的解决方案就是在Debug版本的args.gn中写入enable_iterator_debugging=true参数，然后再执行gn gen out/Debug重新生成文件，再调用ninja编译就可以了。

1.2 LNK2005 "protected: char * __cdecl std::basic_streambuf<char,struct std::char_traits >::eback(void)const " (?eback@?\(basic_streambuf@DU?\)char_traits@D@std@@@std@@IEBAPEADXZ) 已经在 webrtc.lib(int128.obj) 中定义 XWRtc D:\XWRTC\client\windows\XWRtcWinDemo\XWRtc\msvcprtd.lib(MSVCP140D.dll) 1

修改文件

src\build\config\win\BUILD.gn

中static_crt如下

config("static_crt") {
  if (is_debug) {
    # This pulls in the static debug CRT and defines _DEBUG
    cflags = [ "/MDd" ]
    if (use_custom_libcxx) {
      ldflags = [ "/DEFAULTLIB:libcpmtd.lib" ]
    }
  } else {
    cflags = [ "/MD" ]
    if (use_custom_libcxx) {
      ldflags = [ "/DEFAULTLIB:libcpmt.lib" ]
    }
  }

cflags = [ "/MDd", "/Z7" ]
