I am new on this forum so hi everybody. I am here because I would like to develop Desktop applications with Qtlocation module.
I installer on my ubuntu 12.04 qtlocation and I try to deploy an example named mapsdemo. On this computer the mapsdemo file works properly.

So I took all the necessary .so files and the mapsdemo file. I put it all on an other clean ubuntu 12.04 computer.
When I run the mapsdemo file I get that error "No service providers are available".

So my questions are why do I get this error?
I red that a pluging is necessary to be able to use QGeoServiceProvider but I don't really understand what could this be linked to my error?

Can anyone give me a answer or a advice?

Best regard.
