Warning while building project using Qt 5.1 on OSX

qt, qt-creator, qt5, warnings

Solution

The solution is to call cache() in your main .pro file. Then run qmake (from the QtCreator build menu) and rebuild the project. The warning should be gone. Example .pro:

cache()

QT += ...
//the rest of the .pro file

Problem

I am getting two warnings while trying to build Qt projects on Mac (using QtCreator). warning: No .qmake.cache is present. This significantly slows down qmake with this makespec. warning: Call 'cache()' in the top-level project file to rectify this problem. The warning instructs to call `cache()` in the top level project, but I don't find any documentation on how I should do that. I see some bugs logged on qt - https://bugreports.qt.io/browse/QTBUG-31340 - https://bugreports.qt.io/browse/QTBUG-30586 I know this is just a warning, but I am interested in fixing it. Is there any workaround to fix it?
