Could u paste linking error message after setting environment variable or u can check if enviornement variable is set properly by

echo $QTDIR

echo $QTDIR

Hi v.d.,

I don't get any error messages beyond what I showed already, even when defining QTDIR at the command prompt (so that echo $QTDIR returned the intended directory). After the other various attempts to set QTDIR described here, I would still get nothing for echo $QTDIR. Of course, I'm running qtcreator out of the <qt version 4.7.0>/bin directory, but that seems unavoidable; if I move it to <qt version 4.7.1>/bin, it won't open because it fails to find
libExtensionSystem.so.1. But anyway regardless of what directory it's in it seems like just setting QTDIR appropriately would be the better solution, but how to do this...

Your QTDIR should probably be like this:

QTDIR=/home/matt/qt-everywhere-opensource-src-4.7.1/qt
if you have a 'qt' folder under '/home/matt/qt-everywhere-opensource-src-4.7.1'
