1、Error: Multiple commands produce ***************
- 解决办法:
Xcode--File--Workspace Settings--Build System--legacy Build System
2、Error: library not found for -lstdc++. ****
- 解决方法:
苹果的解释是libstdc++已经标记为废弃,建议大家使用经过了llvm优化过并且全面支持C++11的libc++库
拷贝以前Xcode的缺失的 libstdc++、libstdc++.6、libstdc++6.0.9 到新的SDK下。
根据调试方式不同,真机和模拟器文件放置路径存在差异,分别复制对应的Lib文件到下面的路径即可解决Xcode编译报错`:
路径及下载地址如下:
-
For Device
Put tbd copy to the path:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/
-
For Simulator
Put dylib copy to the path:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/
Put tdb copy to the path:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/
