xcodebuild联编没有找到GCC 4.2

Question

我试图运行xcodebuild联编，我收到以下错误：

2011-12-11 04:42:22.834 xcodebuild[9155:4203] error: Error Domain=NSPOSIXErrorDomain Code=2 "Non-zero exit code 127 returned from shell command: /Developer/Library/Xcode/PrivatePlugIns/Xcode3Core.ideplugin/Contents/Frameworks/DevToolsCore.framework/Resources/gcc-4.2 -v -E -dM -arch i386 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk -x objective-c -c /dev/null 2>&1" UserInfo=0x4001a61a0 {NSLocalizedDescription=Non-zero exit code 127 returned from shell command: /Developer/Library/Xcode/PrivatePlugIns/Xcode3Core.ideplugin/Contents/Frameworks/DevToolsCore.framework/Resources/gcc-4.2 -v -E -dM -arch i386 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk -x objective-c -c /dev/null 2>&1, NSLocalizedFailureReason=No such file or directory}

任何想法，这是为什么？我猜测，那是因为我没有GCC-4.2以下路径：

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

截至目前GCC-4.2位于USR/bin中。问题是我如何重定向它？

Answer 1

你是如何选择编译器的？转到Xcode导航器，点击最上面的项目，然后在项目的右侧窗口中（不是目标），然后点击Build Settings。 U并在Build Options部分中，您可以选择编译器。通常你可以选择LLVM gcc-4.x和一些Apple LLVM x。

Answer 2

这可能是涉及到在你的shell的$ CC的变量（它让你的编译器的轨道），你可以找到更多的信息from jMoody on github

从本质上讲，你需要删除$ CC

Answer 3

您用过xcode-select选择你想使用的Xcode版本？

Manpage。
