Sadly the nokia QtCreator packages repository is down and you can't install any additional packages.

So you could use a real N900 connected to the sdk.
Or you could compile under scratchbox for x86 and run your app with the output to Xephyr.
Or find an older QtCreator full setup which is only for maemo, it could be that the emulator is included (I will look and see if I could implement it in the VM image, but atm I am very busy).

Xephyr procedure:

Terminal 1:

Code:

Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac &

Terminal 2:

Code:

/scratchbox/login
sb-conf se FREMANTLE_X86
export DISPLAY=:2
af-sb-init.sh start
(after nothing happens anymore ctrl+c)
run your previously compiled app ./helloworld

to exit:
af-sb-init.sh stop
exit
