      I was proud of myself when I compiled and run an exe on windows using Qt. Then I moved the executable and all of its DLLs to another computer and it wouldn't run. I spent a few hours on IRC in #Qt and couldn't get an answer that would work. My idea is just to get a list of dependencys from people on this forum for the most basic Qt program. Is this possible? I undetstand that I need to include many DLLs just for C++ by itself, but that shouldn't be a problem!

      Please help me, I'm going crazy for Qt.

        Hi,

        Did you already follow this fine wiki "entry":http://qt-project.org/wiki/Deploy_an_Application_on_Windows ?

        Did you try the windeployqt tool ?

          Yes I used that firstly to build my origonal project, but I will try again. I havent tried the windeployqt tool, but someone told me I should. The problem I am having with it is that it only runs in the console, and all the computers I use have the console blocked. Don't ask me why, but it has to do with the library. Do you have any other ideas please?

          Thanks

            Did you solve your problem?
            What I do is either use the windows Dependency walker which I am sure you know about "(depends.exe)..":http://www.dependencywalker.com/
            or,
            I just put my new Qt .exe in a new folder and rename my Qt install folder to something other than its usual name. Run my new .exe and see what dll it says it can't find. I then search the Qt install folder for those missing dlls. You need to be careful because some things need to be in a sub folder of a specific name etc. This is described in the link given by SGaist.

            This is all a bit tedious the first time around but once you get it it does not change much.

            I hope this is of some help to you.

              Thanks, I will try this tommorow. I can only work on this while I am at the public library, right now which is kind of lame. I can't run searches or open up cmd.exe. Any other ideas?

                I'm at the library now, and everything is working fine. I just followed your instructions exactly, and everything compiled.
