QML app deployment with MSVC

Bremenpl

Hello there,
I am trying to deploy my QML application for windows (compiled with MSVC). I used windeployqt to get the initial libs. I then moved the whole deploy dir to a clean Win10 machine and tried to run the app. I was missing some libs so installed the Microsoft Visual C++ Redistributable 2015. After that, running the app doesnt show any window. Running it in the command line also doesnt show what is missing. How can I find out what else I am missing? Those are the modules I am using:

QT += quick widgets core xml multimedia opcua

I would appreciate all help.

@Bremenpl
I would assume, as it's a common enough mistake, you did not specify the qmldir path (pointing to your qml files)

Bremenpl

@J.Hilk Thanks for answer. Do I still need that even though using the Qt Quick Compiler option?

Bremenpl

@J.Hilk I have just added the qmldir option, here is the output:

But still no effect... What else could be the case?

Bremenpl

@J.Hilk Hi, I have made additional steps required (issued the MSVC enviroment setting command), but still, same effect...

Hi @Bremenpl, I don't know the exact cause of your issue, but try the Quick and Dirty deployment: https://wiki.qt.io/Deploy_an_Application_on_Windows Does it help?

J.Hilk

@Bremenpl can you share a screenshot of your deploy folder after windeployqt was run?

@J.Hilk @JKSH Here is my deploy dir:

k:\deploy>dir
 Volume in drive K is RAMDISK
 Volume Serial Number is 65E0-0000

Just FYI, I have just deployed some simple hello world QML app and it works... There has to be missing something from this certain app but I have no clue what.

@JKSH I will try your solution now.

J.Hilk

@Bremenpl
well, nothing missing, from what I can see, at least from the first glance.

Seems like somewhere one qml component can not be resolved.

if you replace your main qml file with a simple colored rectangle, does that load ?

How do you load your qml files in the first place, from a qrc file or local path ?

Guys, dirty deployment works... I will now start the Final deployment (Cleaned up) steps. Thanks for help. I am a bit dissapointed that it came to this but at least it works :P.
