RaspberryPi: module "Qtquick.Controls" is not installed

maxwell31

Hi,
I cross compiled Qt for the RaspberryPi 4, but then run into errors of the type:

qrc:/mainCyclicVoltammetry.qml:6 module "QtQuick.Controls.Material" is not installed
qrc:/mainCyclicVoltammetry.qml:5 module "Qt.labs.platform" is not installed
qrc:/mainCyclicVoltammetry.qml:3 module "QtQuick.Controls" is not installed
qrc:/mainCyclicVoltammetry.qml:6 module "QtQuick.Controls.Material" is not installed
qrc:/mainCyclicVoltammetry.qml:5 module "Qt.labs.platform" is not installed
qrc:/mainCyclicVoltammetry.qml:3 module "QtQuick.Controls" is not installed
qrc:/mainCyclicVoltammetry.qml:6 module "QtQuick.Controls.Material" is not installed
qrc:/mainCyclicVoltammetry.qml:5 module "Qt.labs.platform" is not installed
qrc:/mainCyclicVoltammetry.qml:3 module "QtQuick.Controls" is not installed

I might very well have forgotten to copy some files or set some environment variable. What do I need to do to make Qt find those modules. ldd says that the executable found all the dlls it needs.

I should mention that I tried to set the following environment variables (output of export):

declare -x QML2_IMPORT_PATH="/opt/qt5pi/qml/"
declare -x QML_IMPORT_PATH="/opt/qt5pi/qml/"
declare -x QT_PLUGIN_PATH="/opt/qt5pi/plugins"
declare -x QT_QPA_PLATFORMTHEME="qt5ct"

the content of /opt/qt5pi/qml is

pi@raspberrypi:/opt/qt5pi/qml $ ls
builtins.qmltypes  Qt  QtQml  QtQuick  QtQuick.2  QtTest

and for example of QtQuick:

pi@raspberrypi:/opt/qt5pi/qml/QtQuick $ ls
Layouts  LocalStorage  Particles.2  Shapes  Window.2

Is there something missing?

Hm, the problem is that I am actually missing those modules in the qml directory

The problem was that make install failed due to QtQuick3D. If I compile Qt with -skip qtquick3d it works
