The example code given on this page does not compile (on Ubuntu Linux 10.04 kernel 2.6.32-27-generic in any case), specifically the lines
#include <QSystemInfo> using namespace QtMobility;
It appears that the header file QSystemInfo cannot be found. All subsequent references to the QSystemInfo class do not work.
Removing the QSystemInfo references and commenting out the namespace line solves the problem and the application deploys correctly.
