Qt Creator - Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild

I just installed Qt 5.5 and am using Qt Creator for the first time on OS X. When I first installed Qt, it gave me an error message 'Xcode 5 not installed' which I thought was strange, (I have the Xcode 7 beta), but the install completed successfully anyways.

Now, when I start or open a project, I get the error:

Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild.

When I run /usr/bin/xcodebuild in Terminal, I get the following:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

I'm not sure what Xcode has to do with Qt Creator, unless it has something to do with accessing libraries for cross-platform compatibility, but is there a way to fix this issue?

>= Xcode 8

In Xcode 8, as Bruce said, this happens when Qt tries to find xcrun when it should be looking for xcodebuild.

Open the file:

Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf

Replace:

isEmpty($$list($$system("/usr/bin/xcrun -find xcrun 2>/dev/null")))

With:

isEmpty($$list($$system("/usr/bin/xcrun -find xcodebuild 2>/dev/null")))

~> Xcode 8

Before Xcode 8, this problem occurs when command line tools are installed after Xcode is installed. What happens is the Xcode-select developer directory gets pointed to /Library/Developer/CommandLineTools.

Point Xcode-select to the correct Xcode Developer directory with the command:

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

Confirm the license agreement with the command:

sudo xcodebuild -license

This will prompt you to read through the license agreement.

Enter agree to accept the terms.

If you change content of Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf then it will work only for Desktop kit, not for ex. simulator.

A better way is just to create symlink:

cd /Applications/Xcode.app/Contents/Developer/usr/bin/
sudo ln -s xcodebuild xcrun

so you don't have to change .prf files for all targets.

This will do the trick:

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

Run this in your terminal.

For users of Xcode 8, there is another problem. See here for a temporary solution until Qt 5.7.1 is released:

To summarise:

Open Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf in a text editor, and replace this:

isEmpty($$list($$system("/usr/bin/xcrun -find xcrun 2>/dev/null"))))

with this:

isEmpty($$list($$system("/usr/bin/xcrun -find xcodebuild 2>/dev/null")))
