I got the error message above in starting my QML application. I used console-trdx-image to create the image of my rootfs. I added the following lines to local.conf to enable Qt (local.conf contains qtdeclarative and qtquickcontrols)

IMAGE_INSTALL_append = " \
        qtbase \
        qtbase-fonts \
        qtbase-plugins \
        qtdeclarative \
        qt3d \
        qtgraphicaleffects \
        qtconnectivity \
        qtquickcontrols \
        qtquick1 \
        qtimageformats \
        qtenginio \

The qml-files and code to use QtQuick controls normally resides in the the folder /usr/libqt5/qmlQtQuick/Controls. But there exists no folder Controls at all.If I search the QtQuick control Slider.qml ( find . -name Slider.qml) at the starting point of rootfs there is nothing found at all. Normally the folder Controls should contain about 20 qml files and the lib libqtquickcontrolsplugin.so.

I made another trial removing the lines redirecting output to eglfs in local.conf and make a new run of bitbake and target angstrom-qt-x11-image. Now the controls are visible in rootfs. But of course I want to use ECGLFS, it’s sufficient and my application works fine in using this environment.

Hello

I think I found the culprit:

If one wants the qtquickcontrols one needs to configure qtbase with “-accessibility”
That configuration was applied for X11 builds to work around a compile time error seen with X11 and as a side effect also enabling qtquickcontrol.

I pushed a patch which unconditionally configures accessibility so qtquickcontrol should now also be built when not targeting X11.
