Question

我正在尝试运行xcodebuild，我收到以下错误：

知道为什么会这样吗？我猜这是因为我在以下路径中没有gcc-4.2：

/Developer/Library/Xcode/PrivatePlugIns/Xcode3Core.ideplugin/Contents/Frameworks/DevToolsCore.framework/Resources/gcc-4.2

目前gcc-4.2位于usr / bin。问题是如何重定向？

Answer 1

这可能与你的shell中的$ CC变量有关（它跟踪你的编译器）你可以找到更多信息from jMoody on github

基本上你需要删除$ CC

Answer 2

您是如何选择编译器的？转到Xcode导航器，单击最上面的项目，然后单击项目右侧窗口（而不是目标），然后单击Build Settings。您可以在Build Options部分中选择编译器。通常，您可以在LLVM gcc-4.x和某些Apple LLVM x之间进行选择。

Answer 3

您是否使用xcode-select选择了要使用的Xcode版本？

Manpage

xcodebuild找不到gcc 4.2
