How to deploy Qt project on Windows

[baluk]

Hi,

I want deploy my first Qt app on windows. For this I have run the project in release mode in Qt creator and tried to execute the exe in the release folder.But I get the error that says missing dll. May be I can add that dll but from my googling I see that I will be keep asked for more dll's. So can any one tell me what is the proper way to do this.

Thank You,
Baluk

You need to copy the required dll's in the same folder with your application.exe

You need at least two dll's for MingW runtime:
mingwm10.dll and libgcc_s_dw2-1.dll
you can find this two in the QT_INSTALL_PATH\mingw\bin

And some (depending on what modules you use) for Qt runtime, for example: QtCore4.dll and QtGui4.dll (these are for release build of your application, those for debug have a d in their name and are bigger because they have more debugging information) you can find those in QT_INSTALL_PATH\qt\bin
Note: the dll's from QT_INSTALL_PATH\bin won't work with your application, you need the ones from QT_INSTALL_PATH\qt\bin.

Hi,

Thank you for very quiet detailed explanation and now I can able to run the exe in release folder. I have an other doubt that how can I use this release folder to install it on any other computer ( not just by clicking on the exe file from the folder) and Can I use this folder in Linux also. I would be grateful for any suggestions.

hi balu,


I have an other doubt that how can I use this release folder to install it on any other computer ( not just by clicking on the exe file from the folder)
u need make the package and deployment of ur own. many opensources are available to do tat.


Can I use this folder in Linux also
The exe compiled under windows won't work in linux.
u need to make different exe ,which compiled under linux.
similar to windows , u can put all the reqd libs and exe in same folder.
but for the deployment in another pc , u need to make ur own.

hope it helps
