I want to develop qt widget project (not qt quick project) on raspberry. can somebody point me to any blog or instructions for setting up cross compiler and tool-chain on my Ubuntu.
i am new to Linux embedded development.
Check out http://qt-project.org/wiki/RaspberryPi_Beginners_guide. This is the guide I've been following recently. If you look at the bakeqtpi.sh at the top of the page you'll see it does most of the work for you. Works very well on my setup. includes setting up cross compiler as well as building QT 5 as well.
