Adding Qt backend support to already deployed application: rebuild is needed or replacing opencv_world3xx.dll suffices?

Hello.

Let's say I already deployed a C++ Windows application with its companion opencv_world320.dll which was built without Qt option.

Now user would like to have all Qt backend facilities: in addition to replace the DLL with the "Qt enabled" version, does my application need ALSO to be rebuilt against the opencv_world320.lib created with the "Qt enabled" DLL?

YES. (you also probably need to change some code in your application, where it should be using Qt functionality)

you'd have to:

  • install Qt on your dev box
  • rebuild opencv from src with Qt enabled
  • rebuild your app, so it's actually using qt functionality
  • either have the client install te same Qt version you used, or deploy the Qt dll's along with your app

Thank you, indeed I've already built OpenCV in both "flavors"
