Can't build project after Xcode 6 update

[jimcad]

I recently updated XCode 5 to XCode 6. But now I can't build project any more. This is on Qt 5.3.2

Here is the error message:
@clang: warning: no such sysroot directory: '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk'@

How this can be fixed? Thanks in advanced!

Hi,

You have two choices: copy the 10.8 SDK from Xcode 5.X.X or rebuild Qt yourself

Edit: <your_qt_install_path>/5.3/clang_64/mkspecs/qdevice.pri

change line:

!host_build:QMAKE_MAC_SDK = macosx10.8

to:

!host_build:QMAKE_MAC_SDK = macosx10.9

Clean your project and run qmake again.
