:-1: error: Qt Creator needs a compiler set

Answer 1

I had a similar issue when developing on my Mac -

I was trying to do desktop development with QT creator 3.3.0 based on QT 5.4.0 (Clang 6.0 (Apple)) on OSX 10.9. After trying to manually modify my kits to use GCC, G++, and CLANG. I finally found this really simple solution:

Delete the xxx.pro.user file and then restart QT Creator. It should then automatically pick up your compilers/environments.
