I am a Windows/Linux developer who occasionally builds for OS X - particularly in Qt.

I have a simple Qt project that I have been developing on Windows. I now wish to build it on OS X.

I am running Yosemite. I have installed Xcode 7 and am attempting to install Qt 5.5.

When I run the Qt installer, immediately after the prompt to log in to Qt (which is successful), I receive the following error:

You need to install Xcode version 5.0.0.

Qt installation fails

I have attempted to locate Xcode 5.0.0 on the Apple Developer site, but this is 2 major versions behind the most recent version, and I cannot even find an installer for it.

More to the point, I do wonder why the most recent version of Qt requires a version of Xcode that is considered so old by Apple that it's not even available.

How do I overcome this problem so that I can get Qt installed on OS X?

  • I doubt it will solve your problem, but XCode 5.0.0 appears to be available here under "XCode 5": https://developer.apple.com/downloads/ – Alexander O'Mara Jul 22 '15 at 05:02
  • @AlexanderO'Mara - Not sure how I missed that download. In any case - it did solve the issue. I guess the Qt OS X installer isn't exactly vetted. Thanks! – Dan Nissenbaum Jul 22 '15 at 05:33
  • Could you please also set the question as as solved – Marco Jul 22 '15 at 08:15
  • @Marco I am leaving this question open because - although I have installed Qt on OS X - I think an answer that incorporates an explanation or context regarding why the old Xcode 5 is required would be better than merely a link to it. But, in a few days, if nobody has anything insightful to incorporate into an answer, I will answer it myself and mark it as accepted. – Dan Nissenbaum Jul 22 '15 at 13:16
  • This is a Qt installer bug. Qt itself doesn't need the outdated xcode, and won't use it IIRC. Please report it as such, answer your own question stating that it is a Qt bug, with link to the bug report. – Kuba hasn't forgotten Monica Jul 22 '15 at 22:42
  • Looking forward to an answer to this question, as I too experienced this odd requirement. – johnbakers Oct 07 '15 at 11:34

I ran into the same problem and solved it by following the instructions here. This link describes a similar, but slightly different installer issue.

To summarize, you need to ensure that the Xcode command line tools are installed and set up correctly. I already had them installed, but had to go into Preferences -> Locations in Xcode and set the dropdown to the currently installed version.

The link shows an earlier version of Xcode where the path is actually Preferences -> Downloads -> Components.

Once I'd made this change, the installer continued successfully.

The solution that worked for me (on OSX Sierra XCode 8.2.1) is to open XCode Preferences -> Locations.

There is a drop-down menu named Command Line Tools. Select the available XCode version here. Then restart the Qt Creator installation.

  • This worked perfectly on MacOS 10.13.3 when trying to run the maintenance tool to update from Qt 5.10.0 to Qt 5.10.1. Thanks! – Andrew Mar 02 '18 at 09:33
  • thanx for the method. If QT already installed, after adding location of Command Line Tools, just remove from ~/.config/ QtProject folder :) – Konstantin Streletsky May 24 '18 at 12:55
  • Works for me :) But why doesn't QT mention this as a suggested troubleshooting thing!?!? It just said "Xcode and developer command line tools don't exist" and I was like 'err, yeah they do, what you on about?'. – Gregory Fenn Feb 10 '19 at 12:31

taken from the link above, this resolved my issue:

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

  • That doesn't work. I got the error `xcode-select: error: invalid developer directory '/Applications/Xcode.app/Contents/Developer'`. – Donald Duck May 09 '17 at 16:36
  • What version of OS X are you running, and how was X Code installed? I just tried this again on 10.11.6 with X Code 8.1 and it works still. Take a look at this, might be related to how X Code was installed: http://stackoverflow.com/questions/17980759/xcode-select-active-developer-directory-error If you've used Homebrew there may be a few additional steps, something like this might help: https://apple.stackexchange.com/questions/209624/how-to-fix-homebrew-error-invalid-active-developer-path-after-upgrade-to-os-x – TSga May 10 '17 at 19:08

It also might be related to accepting license agreements.

I faced the same issue described, despite I already had Xcode installed, Command Line Tools installed, and had already made sure XCode active developer folder was selected by making a xcode-select -s /Applications/Xcode.app.

Following the instructions in @gus answer, I launched Xcode to check if the command line tools was really installed and properly selected. It asked for license agreements. Going to Preferences -> Locations as suggested, I found that everything was OK.

Relaunching Qt installation after exiting Xcode, it was now working. So maybe performing a sudo xcodebuild -license accept could also help (or launch XCode at least once like I did and accept agreements when prompted).

Note that on XCode 14.3.1, Ventura (macOS 13), described option is located in XCode -> Settings -> Locations

Issue faced using qt-unified-macOS-x64-4.6.0-online dmg

For me closing the prompt and smashing keys (alt F4, I know that its not windows) before the next prompt opened worked... qt is running fine now, as it doesn't need the old version.

you can find the old version of XCode on the the Apple offical site here and download .dmg of xcode 5 or 6.1 for example :

I do this and it's ok for me.
