使用XCode编译时期望的类名与类名相同的c++

Expected class name C++ with same class name when compiling with XCode

本文关键字:c++ XCode 期望 使用 编译      更新时间:2023-10-16

我正在尝试用XCode编译WebRTC (c++)。最后一个也是唯一一个构建libwebtrc的项目"webrtc"失败了,错误:

/Volumes/Data/webrtc/webrtc/src/webrtc/audio/audio_receive_stream.h:33:49: Expected class name
/Volumes/Data/webrtc/webrtc/src/webrtc/audio/audio_receive_stream.h:36:28: No member named 'AudioReceiveStream' in namespace 'webrtc'; did you mean simply 'AudioReceiveStream'?

有两个类名为"AudioReceiveStream"

- Class 1:  webrtc::AudioReceiveStream
- Class 2:  webrtc::internal::AudioReceiveStream

如果我使用忍者来构建,不会出现问题。代码未修改

XCode设置为:XCode设置

谢谢!

在XCode "Build Setting"中搜索"USE_HEADERMAP"并设置为NO
