Error: Could not resolve SDK path for 'macosx10.8'

Question

So I just installed qt around 5 minutes ago, and when I wanted to code a simple line of text in the Push Button and try to run it, I got this error:

:-1: error: Coul

Answer 1

I'm running Qt 5.7.1 on Mac OS 10.12.2.

None of the above answers involving adding !host_build:QMAKE_MAC_SDK = macosx10.12 to a file worked for me.

What did work was a small reconfigure on the XCode side of things as described here, the key step being entering

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

in the command line.

What caused the problem for me was that I installed the XCode command line tools before installing XCode itself which apparently makes it hard for Qt to find the Mac OS SDK.

Answer 2

For Qt 5.7 and macOS Sierra

Navigate to where you installed Qt (default /Users/your username/Qt) using finder

Go to the subdirectory 5.7/clang_64/mkspecs directory

Open the file called qdevice.pri with a text editor

Add line on end file

!host_build:QMAKE_MAC_SDK = macosx10.12

Answer 3

In QT 5.7.0, Xcode 8.0 (8A218a), Mac OSX El Capitan (10.11.6), this issue happened from sudden in already configured environment. 5.7/clang_64/mkspecs/qdevice.pri no longer contains QMAKE_MAC_SDK line to modify.

I suspect some XCode part got silent update and I issue appeared again. This worked:

1. open XCode and let it reconfigure again (automatic action upon start)
2. delete .pro.user file from the project
3. reopen project in QT

Answer 4

In my case , I have just opened xcode again. It start installing some components. Once it finished , I open Qt again and everything start working fine.

Answer 5

All I had to do was accept the Xcode licence by running: sudo xcodebuild -license accept

Answer 6

The problem is that the online installer for Qt currently supports OSX 10.8 (Mountain Lion) by default, and I'm guessing you are on 10.9 (Mavericks) or greater.

There is a workaround:

• Navigate to where you installed Qt (default /Users/your username/Qt) using finder
• Go to the subdirectory 5.3/clang_64/mkspecs directory
• Open the file called qdevice.pri with a text editor
• Change the line !host_build:QMAKE_MAC_SDK = macosx10.8 to:
  • !host_build:QMAKE_MAC_SDK = macosx10.9 if you are on OS X 10.9 (Mavericks), or
  • !host_build:QMAKE_MAC_SDK = macosx if you are on OS X 10.10 (Yosemite)
• Save the file and restart Qt Creator
