my question is when i build release mode my simple app,how i can create exe file?
i tested this solution:

Let's say you've installed QT under c:\qtsdk
Open your project, and compile it in release mode.
Go to this directory: C:\QtSDK\Desktop\Qt\4.7.4\mingw\bin -- it contains all shared libraries. Debug libraries end with a "d" -- frex, QtCore.dll is release version, while QtCoreD.dll is debug version

Copy at least these files into your release directory (where your .exe lies)
    mingwm10.dll
    libgcc_s_dw2-1.dll
    QtCore4.dll
    QtGui4.dll

I just built, tested and deployed a dummy project this way.

but after copy file it return other dependency file,i again copy it and an other error!!!!
please guide me
