How to copy/include the DLLs my application needs?
-
Hello,
How do I modify the Qt project settings so that it automatically copies whatever Qt/MinGW DLLs my application needs to the build output directory? (So I can zip it up and ship to any modern Windows machine with no Qt installed.)
Qt has a lot of DLLs, and I don't know exactly what I need.
I know about using the depends tool, but that is a manual process. (I assume Qt/MinGW already know what's needed since they just did the build and are privy to the locations of their own specific DLLs)
Thank you

You can "build standalone Qt application for windows with all required files":http://developer.qt.nokia.com/wiki/Build_Standalone_Qt_Application_for_Windows

Careful with the LGPL restrictions about static.
A simple method (on Windows - since we are talking about .dll) is to not set anything in the path, then open the built application from Explorer and it will tell you which .dll to copy - you need two for MinGW run-time and one per Qt module.
A little more complicated is with plugins and image-formats, but after a little trial-and-error you can solve the puzzle.
//Anyway nonot1 idea would be and interesting tool ;)

It's been mentioned "elsewhere":http://developer.qt.nokia.com/forums/viewreply/32996/ that statically linking Qt is not the best solution. (Plus is problematic with LGPL, as the above poster said.)
Thus, my question about auto-bundling the DLL files.

You can read the official Qt documentation about "deploying Qt's libraries":http://doc.qt.nokia.com/latest/deployment.html#deploying-qt-s-libraries and create an installer for your application using "NSIS":http://nsis.sourceforge.net/Main_Page
