Meggo harmattan several problems

[AlterX]

Hello,
I'am trying to do an app, but I'am having so many problems!!!!
First of all, my app doesn't start tapping on icon, but just using QtCreator (it seems equal using 2.8 or QtCreator made by Nokia) and then when I close my app swiping down that, QtCreator sticks and gps (my app is using that) remains active...If I try to start it from within terminal, it starts but gps doesn't start...
I've created new project from scratch, using oder projects working very well but whatever I'm doing result is always the same above...
I've forgotten how much pains n9 made!
I've tried it on n9 and n950 without any result...

Ok so, I have seen my problem is under linux and not under windows...
