linuxdeploy: appimage is only working in local environment

[Yunus]

Hi all,

I have a qml project and I want to deploy it as appimage . I am using linuxdeply to achieve that and here is the documentation.

When I followed the steps, I got an appimage at the end and it works fine in my pc without a problem. Since this is an appimage, I am also expecting this to work in my other linux PCs. But when I moved this appimage to other PCs, its not working and giving me error in the terminal as follows:

:~/Documents/documents/appImage/QtQuickAppRef/build$ ./QtQuickApp-82a3b40-x86_64.AppImage 

QQmlApplicationEngine failed to load component
qrc:/main.qml:2 module "QtQuick.Window" is not installed

Here is my .pro file to deploy:

TEMPLATE += app
QT += quick
QT += qml quick
QT += widgets
QT += core
CONFIG += c++11 release
CONFIG += link_pkgconfig
PKGCONFIG += opencv4

SOURCES += src/main.cpp
SOURCES += src/opencvimageprovider.cpp
SOURCES += src/videostreamer.cpp

HEADERS += src/opencvimageprovider.h 
HEADERS += src/videostreamer.h

RESOURCES += src/qml.qrc

QML_IMPORT_PATH += /opt/Qt/5.15.2/gcc_64/qml
QML2_IMPORT_PATH += /opt/Qt/5.15.2/gcc_64/qml

QML_DESIGNER_IMPORT_PATH =


# Default rules for deployment.

unix {
    isEmpty(PREFIX) {
        PREFIX = /usr
    }

    target.path = $$PREFIX/bin

    shortcutfiles.files = resources/qtquickapp.desktop
    shortcutfiles.path = $$PREFIX/share/applications/
    data.files += resources/qtquickapp.png
    data.path = $$PREFIX/share/pixmaps/

    INSTALLS += shortcutfiles
    INSTALLS += data
}

INSTALLS += target

DISTFILES += \
    resources/qtquickapp.desktop \
    resources/qtquickapp.png

What can cause this and how can I figure out this issue, thanks all

Hi,

Based on a quick look of the project README, did you specify QML_SOURCES_PATHS ?

[Yunus]

@SGaist Thanks for your reply. Where should I specify that ? inside .pro file ?

Also where is the location of this path, can you give an example.

Thanks

[SGaist]

On the README of the project it's written that this is an environment variable. Define it before the call to the command. You can do it on the same line.

[Yunus]

@SGaist yes I got the point. but where is this path and what is that ? I tried couple of paths:

/opt/Qt/5.15.2/gcc_64/qml

/opt/Qt/5.15.2/gcc_64/include

These folders are inside my qt installation folder, and I tried like:

export QML_SOURCES_PATHS=/opt/Qt/5.15.2/gcc_64/include

but results are same, where QML_SOURCES_PATHS locates actually?

[SGaist]

It should point to your application QML sources.
