Unable to compile QT Create Quick Application Project

Question

I am new to QT Creator and I have installed QT Creator 5.6.2 with MinGW 4.9.2 32bit. I have a problem compiling a quick application project as it always shows this error mes

Answer 1

I am a beginer in QT but it is easy to solve... Just go to Projects and change the content at Build Directory for a valid directory. Good Luck

Answer 2

By chance I stumbled across the exact same issue today on a native Ubuntu computer and I found the solution here: https://bugreports.qt.io/browse/QTBUG-59509

"Please go to Preferences > Build & Run > General and click "reset" behind "Default build directory". Looks like this is an incompatibility when using Qt Creator 4.3 without having used Qt Creator 4.2 before, and then going to Qt Creator 4.2 instead."

I thought to share the solution, because it seems to be a quite undocumented issue!
