Error while building/deploying project navi (kit: Qt 4.8.4 (4.8.4))
When executing step 'Make'

Nothing very informative in this output. Clean the build, run qmake and then build again.

Are you sure you have installed Qt5, when the output clearly states your kit is for Qt 4.8.4?

Thanks for reply . i have installed Qt 5 with Qt libraries 4.8.4 for Windows (minGW 4.4, 317 MB) and qt-creator-windows-opensource-2.6.2. i have to say im really new in Qt. i have cleaned the build but how i can run qmake ?

thanks if you help me to solve this problem

In Qt Creator, right click on your project, select "Run qmake" then "Build project".

No need to install both Qt5 and Qt4 when you are new to Qt. Pick one.
