我刚刚更新到OS X Mavericks中的命令行工具的最新版本，现在在编译我的(以前有效的)代码时会引发以下错误

有谁知道如果更改此行
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
从SDK 8到9可以工作吗？如果是这样，我可以在Qt5的参数中的哪个位置进行更改？
最佳答案
供其他人引用，我通过编辑平台mkspec文件解决了该问题:
/users/nic/Qt/5.3/clang_64/mkspecs/qdevice.pri
更改以下行:
!host_build:QMAKE_MAC_SDK = macosx10.8
对此:
!host_build:QMAKE_MAC_SDK = macosx10.9
确保清理项目并再次运行qmake。
