Since MeeGo uses cross-plate QT as the development environment because of Nokia, MeeGo SDK learning will also begin with QT. We have prepared two development environments, one is the MeeGo Handset simulator and the other is a local Linux (using a local environment, because the local efficiency is high, since it is only learning, it is convenient to use, finally, verify it in target ). Here we only conduct the learning and verification environment, and do not use the complete environment includin
