Compiling Qt-App gives me lib***.so instead of normal binary

Spice
Hi,

as the subject describes, if I compile/build my QT-Application, I got a
file called libnameofProject.so but I want the compiler to generate a
normal binary file, which I can upload on the Mini2440. Does anybody knows
this problem and how to fix? I did not change any compileroptions. The
first time compiling the Project gives me a normal binary which works on
the Target but compiling any more gives me a .so file... 
I would be very thankful if someone could help.
Thank u very much
