ld: library not found for -lstdc++.6.0.9
xcode 10 已经没有libstdc++.6.0.9.tbd 这个库了

解决办法1.找第三方更改
2.把9.4的这个拷贝到10 对应文件路径下面
文件路径
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/
libstdc++.6.0.9文件资源可以在百度网盘获取, 提取码:njj8

Xcdoe11及以上:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/libs

| 模拟器编译 | iPhoneSimulator | libstdc++.6.0.9.tbd | 206,800B | /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/ |
| iOS真机 | iPhoneOS | libstdc++.6.0.9.tbd | 209,673B |/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/ |
| macAPP | MacOSX | libstdc++.6.0.9.tbd | 206,751B | /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/ |
