Your project tries to link some C++ code which makes use of a C++11 concept not supported all iOS platforms.
您的项目尝试链接一些 C++ 代码，这些代码使用了并非所有 iOS 平台都支持的 C++11 概念。
I think thread_localis allowed beginning with iOS 9. Try to set the deployment target to iOS 9 or later.
我认为thread_local从 iOS 9 开始是允许的。尝试将部署目标设置为 iOS 9 或更高版本。
The offending code is in base_logging::LogMessage::Flush().
违规代码在base_logging::LogMessage::Flush().

Changing the deployment target to 9.0 worked for me
将部署目标更改为 9.0 对我有用
open xcode:
打开xcode：
- select YOUR_PROJECT_NAME from target
- change Deployment target to 9.0 or greater under Deployment Info tab.
- 从目标中选择 YOUR_PROJECT_NAME
- 在部署信息选项卡下将部署目标更改为 9.0 或更高版本。
Hope it helps !
