thx, Larry, your link is really useful for me. Infact reading it I see that I was searching the plugns in wrong paths. :)
So I set the right path in the environment var. export QT_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/qt4/plugins Also I check that in plugin there is available che jpeg library. but still the map is not generate in jpeg format. Now I'm investigating to see if there is a problem of plugins version. Infact I read that qt is really sensible to the exact version of plugins.
