iphone - 在命令行中调试ios问题-Xcode

Question

我为iPhone构建了一个项目，并在Xcode 4.3.2中对其进行了调试，效果很好。但是，我想在命令行中调试它，所以我运行:

xcodebuild -target NAMEOFTARGET -sdk SDKPATH -configuration Release

它应该与Xcode中的相同，但出现一些错误，并且无法编译!也许有人可以帮忙...

Answer 1

它正在/opt/中寻找GCC，但没有找到它。这不是与Xcode捆绑在一起的GCC的标准安装位置。以下命令将告诉您Xcode在哪里寻找其开发人员工具:

xcode-select -print-path

要更改它，请运行:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

该路径用于通过App Store安装的标准Xcode安装位置。如果已将其安装在其他位置，则必须相应地更改路径。
