When trying to build QT Creator hangs for like about 40 seconds and resume telling that "Could not start process "/usr/bin/qmake-qt4""

I think this is a bug, because I got some update through Arch Linux of QT and since then it doesn't build anymore.

QTCreator hangs for a while and after some time in the compile output it says this:

18:24:18: Running steps for project untitled...
18:24:48: Could not start process "/usr/bin/qmake-qt4" /home/gerstrong/workspace/sandos/test/untitled/untitled.pro -r -spec linux-g++ CONFIG+=debug CONFIG+=declarative_debug
Error while building/deploying project untitled (kit: Desktop)
When executing step 'qmake'
18:24:48: Elapsed time: 00:30.

The most funny thing is that /usr/bin/qmake-qt4 is installed on the system and I can execute it by hand. Can somebody help me here.

CMake has the same issue. QTCreator is not able to execute it anymore.

I will try the RC of qtcreator to see if it also happens there.

Btw. I had many IDEs and made them crash a lot of times. Also KDevelop which right I'm forced to use, since I cannot build anymore with qtcreator.

Your product is very solid and has a lot of cool features. Thanks for bringing such a great product!
