构建 Apple 的 "Son of Grab" 项目

Question

我想构建和学习 Apple 的演示项目 Son of Grab。

我下载了存档并用 Xcode 6.1 打开了项目。构建失败，出现错误：

Undefined symbols for architecture x86_64:
  "_ChangeBits", referenced from:
      -[Controller awakeFromNib] in Controller.o
      -[Controller toggleOffscreenWindows:] in Controller.o
      -[Controller toggleDesktopWindows:] in Controller.o
      -[Controller toggleFramingEffects:] in Controller.o
      -[Controller toggleOpaqueImage:] in Controller.o
      -[Controller toggleShadowsOnly:] in Controller.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我尝试将基础 SDK 更改为 10.6 然后 10.7，希望代码依赖于过时的 SDK。但是它仍然失败并出现相同的错误。
