You need to copy/install your application program and the required dlls to your friends machine. Checked out this [developer.qt.nokia.com]

I think this is more general: Deploying Qt Applications [developer.qt.nokia.com]

Thank u i got error message saying….
“The procedure entry point _Z5qFreePv could not be linked in the dynanic link library QtCore4.dll” !!!

You first need to release the application and put the Qt libraries in it’s folder (Hm…). I think the error you’ve got is some “sort” of problems with the libraries if i’m not wrong.

Try using C:/QtSDK/QtCreator/bin libraries. Well, or wherever you have your Qt Creator.

Please do not use the libraries found in C:\QtSDK\QtCreator\*. That is a custom Qt build for Qt Creator and not what you used to build your code. Please use whichever Qt version you used to build your code with instead.
