Steps to run a QML application on IMX7D with Non commercial licence

Hi,

So I’ve been trying to compile a QML program lately, without success. My goal is to compile for the moment a simple “QML” hello world.
#include <QtQuick/QQuickView>
#include 

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QQuickView view;
    view.setSource(QUrl("qrc:///main.qml"));
    view.show();
    return app.exec();
}

Unluckily, I’ve not been able to make it work. Indeed, my compilation (on the target) gives the following error (in the linker):

undefined reference to `QQuickView::QQuickView(QWindow*)' 
undefined reference to `QQuickView::setSource(QUrl const&)'
undefined reference to `QQuickView::~QQuickView()'

In my layer.conf, I’ve got the following, in addition to your base layer.conf:

IMAGE_INSTALL_append = "qtbase-plugins \
    qtbase-tools \
    qtbase-examples \
    qtdeclarative \
    qtdeclarative-plugins \
    qtdeclarative-tools \
    qtdeclarative-examples \
    qtdeclarative-qmlplugins \
    qtsensors \
    qtserialport \
    qtquickcontrols \
    qtquickcontrols2 \
"
PACKAGECONFIG_append_pn-qtbase = "qtquickcompiler tools debug developer examples no-opengl tests widgets"

#DISTRO_FEATURES_remove = "x11 wayland"
IMAGE_INSTALL_remove = "eglinfo-x11"

I then bitbake the console image.

I’ve tried several Qt configuration, and tried to play a bit with the x11 settings, but this always lead to the same messages.

Any idea?

Regards,

Matthieu
