How to add the Dll to the application??

[Gokulnathvc]

I have completed a project in Qt. After everything, if i run the exe alone, it says it needs that dll and 4 more dlls, Anyway the final product will be the single exe file. So how it could be achieved by including all the dlls and make working the single exe for the required application.

Before you statically link everything into one executable you might want to check the licensing agreements for each DLL. For example, unless you have commercial license for Qt, you must allow people to relink your application (eg, provide source or object code). Some libraries may not work correctly when statically linked.

There is no need for static linking. When DLLS does not work, there could be a few reasons:

1. DLL is not found in the path: (Add the path to QT and your DLLs (if any) in system settings (or start it from commandline and do a SET PATH=%PATH%;X:\PATH\TO\MY\DLLS;X:\PATH\TO\QT\BIN;
2. DLL has not the correct references: To use functions/variables in DLL, you need EXPORT/IMPORT settings. Please search for Q_DECL_EXPORT and Q_DECL_IMPORT in QT documentation...

Here it contains the importing and exporting of the dlls but how it can be done.. Could anyone help me in this please.. How to include mingwm10,libgcc_s_dw2-1,QtCore4,QtGui4,QtNetwork4?

Just copy them to the same directory as your executable.

If you statically link you have to agree to different licenses than if you don't, therefore it's far easier to just dynamically link.

I want to build only the exe file not the supporting files with it. How to link the dlls statically.. or adding the dlls. Just one big exe file which contains all the dlls in it

You'll need to recompile Qt - see 'Deploying Qt Applications' -> http://doc.qt.nokia.com/latest/deployment.html
