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

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
