Problems when i launch Qt executable from folder

[jsulm]

@Adrian.Aioanei You also should check whether you copied all needed plug-ins

[Adrian.Aioanei]

Thank you for your replay @J-Hilk , @Ni-Sumi
I will try when i will go back to my pc to see if this solution solve the problem. :)

[Adrian.Aioanei]

I have try and also doesn't work.
Can have a connection with the path to the build directory?
I have change that path from Qt and now i receive a warning and say "The build directory needs to be at the same level as the source directory".

[jsulm]

@Adrian.Aioanei Build directory? Why? You want to deploy your app, right? Check http://doc.qt.io/qt-5/windows-deployment.html

[Adrian.Aioanei]

Yes, that's what i have done but still doesn't work. Every time when i launch my application popup a little window witch doesn't have any connection with my application. Here is what i get.

This is not how looks my application when i lunch from Qt. It has some buttons, labels and so on.

[jsulm]

@Adrian.Aioanei Set QT_DEBUG_PLUGINS to != 0 before starting your app in cmd and see whether any plug-ins are missing or failed to load. See http://doc.qt.io/qt-5/debug.html

[Adrian.Aioanei]

I will try and also i will try on a new machine to see if the result is the same.
I will came back with results.
Thanks :)

I have try on a new workstation and i have rebuild the project but the result is the same. I have made deploy using windeployqt following this video link. I have study the executable with dependency walker show me some missing dll. I was thinking the dll problem is solved by windeployqt . Here is a print

That dll name doesn't tell to much.
PS: I have also try to make an empty QML Quick 2 Application and make deploy. Also doesn't work...

UPDATE : I have close the application and rebuild again and now say :

qrc:/test.qml:4:1: module "QtQuick.Controls" is not installed
qrc:/test.qml:5:1: module "QtQuick.Controls.Styles" is not installed

Hi,

You should use the -qml parameter of windeployqt so that it can go parse your application qml files and deploy what's needed to support them.

[Adrian.Aioanei]

Yes @SGaist , that was the problem.
The above error appears in qt creator when i have created the new project and i don't understand why.
I just made a new project and i have copy all the file from the old one to the new one and show this error when i try to launch.
The old project works fine without any error.
Do i need to setup something from project configuration ?

[SGaist]

Do you mean from Qt Creator ?

[Adrian.Aioanei]

Yes. I don't remember if i have setup something to my previews project, but the think is the second doesn't work.

[SGaist]

Which version of Qt are you using ?

Did you setup the .pro file the same way ?

[Adrian.Aioanei]

Yes, i have
Sorry for my delay. :D
There was the problem. Now works fine.
Thank you very much all. :D
