I have a QML plugin build successfully, but during run time, I have the following error:

plugin cannot be loaded for module "GuiTestInit": Cannot load library /usr/lib/qt5/qml/GuiTestInit/libqmlguitestplugin.so: (/usr/lib/qt5/qml/GuiTestInit/libqmlguitestplugin.so: undefined symbol: _ZN7GuiInitD1Ev)

Could anyone help on this ?

Thanks,

Alex
