I want to cross compile a QT Application for ARM-Cortex A8 device on (x86) Ubuntu.
How can I do this process.

Secondly, The Device has QT-4 but version of my app is QT5. I think I have to cross compile for QT5 source library. Is that right?

Can I use the buildroot or Yocto for QT5 cross compile process?

Thanks

I installed buildroot but my device not supported by buildroot completly. There is no def_conf file for my device.

I used arm-gnueabi compiler but not successfull.
