objective-c - 构建Apple的 "Son of Grab"项目

Question

我想构建和研究演示项目Son of Grab来自苹果公司。

我下载了存档并使用 Xcode 6.1 打开该项目。构建失败，并出现错误:

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，然后更改为 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。

在这里找到答案:Linking error for inline functions
