How to create executable file for a Qt Application?

Here is what I did and I got it to work after some time;after making sure that your program builds inside Qtcreator,go to the directory that contains your exe and double click on it.(I'm using windows and don't know if it is the same on other platforms).A window should popup telling you which .dll is missing.Go to the directory where Qt is installed and type the exact name in the search bar(top-right in Windows 7) and the dll should show up in search results.Right click and choose open file location.Copy the file where your exe is located .Double click on the exe again.If another .dll is missing repeat the same thing until none is missing.In the end your program should run. Hope this helps.

Do these steps:

1- Open qt command-line window.

2- Go to the directory which .exe file exists (using cd command).

3- Run windeployqt.exe --quick . command

4- Run your exe file and enjoy it!

Basically you have to look for mingw subfolder deep into qt tree, where qt utilities reside, and copy needed dll's.

These are the steps I follow, based upon QT 4.7.4, for packaging the application with correct shared libraries.

1. Let's say you've installed QT under c:\qtsdk
2. Open your project, and compile it in release mode.
3. 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

4. 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.
