Porting Qt 5.3.2 to Ubuntu LXDE on BD i.MX6Q SABRE-Lite with HW graphics acceleration

I'm porting the Qt 5.3.2 source to my i.MX6 SABRE-Lite. Everything's working well except QPA (Qt Platform Abstraction) related issues. I've no success on starting my test application (QtWidget-Based GUI with a child widget serving as OpenGL-Rendering surface). EGLFS compiles fine but runs into Seg Fault during application startup (same with plugins DirectFB and XCB). According to the Qt configure summary XCB should run fine.

 

The cause of the problem seem's to be in the OS driver setup or some incompatibillities between the Kernel- and the OS-libraries. I'm using the OS-libs from the VIVANTE GPU SDK (gpu-viv--x11-bin-mx6q-3.10.17-1.0.0) because Qt should be built on top of an X11 environment with Openbox window manager.

 

Does somebady made some similar experiences?

What should i consider to get Qt 5.3.2 running on top of X11 (LXDE) with OpenGL support?

 

My setup:

- Boundary Devices SABRE Lite (i.MX6Q)

 

OS:

- Kernel 3.10.17-8-boundary-4t3

- Ubuntu with LXDE (from

- gpu-viv--x11-bin-mx6q-3.10.17-1.0.0 installed

- hard float toolchain
