Qt Quick cross compiled application didn't show images on raspberry pi 4

[amina]

I cross compiled Qt5.14.2 for my raspberry pi 4 on a raspberry pi OS lite

after that I created a Qt Quick application on my Ubuntu and I integrated images in my qml file

Image {
        id: compteur
        x: 223
        y: 102
        width: 570
        height: 227
        source: "images/b2.png"
    }

so the image b2.png on my ubuntu is under ~/Desktop/test_v1/images and the executable test_v1 was generated under ~/Desktop/build-test_v1-Qt5pi-Release

on my raspberry pi I copied this executable and copied also all the directory test_v1

but when executing the application it worked well but the images didn't show up

I tried also to put the images and the executable in the same directory but couldn't work also.

if you know what should I change please tell me !

Thank you in advance

Did you consider using Qt resources?

Otherwise you should be able to to remote debug the application from a desktop. This should give you some error messages with a clue what is happening.

Thank you , I didn't know about the Qt resources , I will try it and keep you updated.

and for the remote debug , I couldn't do it because I cross compiled Qt for a lite version .. even eglfs is not available. when I want to test something I just execute it on the raspberry with the framebuffer linuxfb

@koahnig Thank you so much, it works now with the Qt ressources.

I will post what I did maybe it will help someone!

so under my test_v1 directory I createad a file image.qrc (I used nano to create it)
after that in qtcreator I added to my project this file (right click on the project -> add existing files-> choose image.qrc)

image.qrc containes :

<!DOCTYPE RCC> <RCC version="1.0">
<qresource>
    <file>images/b2.png</file>
</qresource>
 </RCC>

the image b2.png is under test_v1/images
