[SOLVED] Again on Windows Deployment

  • Hello.

    I have been trying to deploy my (quite simple) Qt/QML app to Windows (8.1, if that matters) and I simply can't do it, despite reading every thread in this forum and guides all over.
    First, I tried to do it the standard way:
    MyApp Folder
    ---- MyApp.exe
    ---- Qt5Core.dll
    ---- // All other required DLLs

    ---- platforms
    -------- qwindows.dll

    ---- bearer
    -------- qgenericbearer.dll
    -------- qnativewifibearer.dll

    ---- imageformats
    -------- // all .dll files

    ---- QtQuick
    -------- Controls
    ------------ qtquickcontrolsplugin.dll

    ---- QtQuick.2
    -------- qtquick2plugin.dll

    ---- qml
    -------- MyApp
    ------------ main.qml

    But this sh*t won't start!!! So I tried to add C:\Qt\5.2.1\mingw48_32\bin to Windows's PATH and place all DLLs inside there, but still no go.
    I then used DependencyWalker to see what the hell is missing, and here's what it says:


    So, looks like some Windows API are missing, right? Then why does that app start without a problem when launched from Qt Creator? And those missing .DLLs are obviously not installed in the Qt folder...

    I also tried to use process explorer from the Sysinternals suite (by Russinovic) to see which .DLLs are used by the working exe (opened in Qt Creator), and the ones I have listed above are all those listed by process explorer, so I should not be missing anything...yet, nothing works!!! Please help...

    You also need all the qmldir files in your QML plugin subdirectories.

    Ignore the Windows DLLs. Those are false positives -- you'll see them even when you try to open a Microsoft program like Visual Studio.

    If you still have no luck, try this guide: http://qt-project.org/wiki/Deploy_an_Application_on_Windows It ensures that no required file can possibly be missed.

  • That was it...thanks! I saw that post and I was sure I had already tried to add those files to the deployment folders. Maybe I did it when still missing other files...what a confusion :D
