I'm trying to get Qt Embedded applications running on a mobile device (Dingoo mobile game device). I compiled Qt Embedded and copied the libs and some examples to the device.

However, when I try to run an example, I get some weird error messages:
> ./clock -qws
QWSServerSocket::init: Function not implemented
QWSServerSocket: unable to create socket.
QWSServerPrivate::initServer: server socket not listening: Illegal seek
Failed to bind to /tmp/qtembedded-0/QtEmbedded-0

I already tried deleting the contents of the /tmp folder and make it writable for all users as was pointed out in some forums, but nothing helped so far.

Does anybody have an idea of what I did wrong?
