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？

Answer 1

1. 您遇到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。把错误一一找出来 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 在您的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。

2. 还要检查您的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 / 首选项 / 下载 / 组件，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。
