Hello,

I have successfully compile qt for imx6 target and able to run application on my IMX6 board with -qws option
Eg: ./MyQtApp -qws.
I have also running matchbox desktop.

But when qt app runs my desktop goes green screen beside.

What changes should i do?

To run Qt application with X11 it should be configured without embedded option only by providing -arch arm and other option.
but the root file system should consist for X11 libraries for arm architecture.

Same thing i have managed to build root file system with X11 libraries. I have created mkspec file .
when i configure following error is thrown:

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /mnt/suraj_R_D/qt-everywhere-opensource-src-4.8.0/mkspecs/qws/linux-arm-g++.

But all libraries are exist in my root file system.
I have tried by setting LD_LIBRARY_PATH also.
But still not working.

What changes i should ?

Hi,

If Qt is built for embedded it will be running using qws.
For qt running with xserver, It should not build with qws and embedded option while configuring.
Create own qmake file in mkspec directory , provide the x11 libraries for arch you are building.
