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.
