Tons of errors after reinstalling Qt-Creator Clang Code Model

[pauledd]

Hi

I am dogged by bad luck after messing with Qt-Creator reinstalls. My current
project just worked fine and I had no errors. After reinstalling and reconfiguring my kits to crosscompile for RaspberryPi, I get a LOAD of errors in the same project, but if I BUILD the project I get NOT ONE error.
In the editor window I get those errors indicated by a red O cirlce.
Even in the main.cpp I get now an error:

main.cpp:6:5: error: cannot initialize object parameter of type 'QWidget' with an expression of type 'MainWindow'

And then this continues in my mainwindow.cpp like in a battlefield:

But again, if I compile the project I just get one tiny warning for an unused parameter...

I guess the problem is in the "Code Model"? I dont really understand how this works. I have this settings:

My Kit is a bit specific because I use GCC from the Raspberry Toolchain (4.9.?) and as sysroot a copy from my raspberry pi.

This worked without errors until recent Qt-Creator reinstall.

I also get this warning about "code model could not parse in included file":

Any Ideas why bad luck hunts me so hard ? :)

Solved. Under KITS->compilers I obviously had selected a wrong g++ compiler.
I have to use this one:

~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++

as decribed here:

Once selected all errors gone.
