Question

我正在尝试编译Mac应用程序，但Xcode给了我这个错误：

有什么想法吗？

您获得的错误是由于项目设置造成的。这是很可能是一个较旧的项目，建立在较旧版本的OS X / SDK上比你目前正在运行的。逐个获取错误并进行搜索是什么导致了他们每个人。例如，
```
cc1obj: error: unrecognized command line option "-Wno-implicit-atomic-properties"
```
与Implicit Atomic Objective-C Properties LLVM编译器有关在项目设置中启用警告。尝试删除此设置并检查是否仍然出现错误，等等。
同时检查命令行工具是否安装正确，因为这似乎是一个命令行工具问题。它们是单独下载的。转到XCode / Preferences / Downloads / Components，您应该在列表中有一个名为命令行工具的项目，其状态应为“已安装”。如果没有，请下载并安装它。希望这会有所帮助。
