What files are needed for a release build with Qt Creator?

I compiled the standard qt widget project (Desktop Qt 5.4.0 MSVC2013 32 bit) as a release build with QtCreator 3.3.0 on Windows 7 32 bit and put the qt libraries in the same folder (Qt5Core.dll, Qt5Gui.dll, icudt53,dll, icuin53.dll, icuuc53.dll) And when I start the program the error (roughly translated) "... doesn't work anymore" appears.

When I do the same thing with the debug release and put the appropriate debug libaries in the folder it works.

What do I have to make differently with the release build?

Thanks in advance for any help!

Solution

Try to deploy your application using The Windows Deployment Tool which could be found in QTDIR/bin/windeployqt.exe. It automatically puts all necessary files in your application directory.

Open your command prompt and add the path to your Qt directory and it's bin folder to the PATH variable like :

set PATH= path\to\Qt\bin

Next run the windows deployment tool with your application path as the argument:

windeployqt.exe  <path-to-app-binary>

This way you make sure that the deployed application would work on any computer and you have included whatever necessary.
