@isan You need to cross compile QtCharts for Raspberry Pi using your cross-compiler and cross compiled Qt.

I get qtcharts module and make it

git clone git://code.qt.io/qt/<qt-module>.git -b <qt-version>
cd <qt-module>

~/raspi/qt5/bin/qmake -r
make
make install

Hi,

Did you cross-compile it or did you build it on the Pi directly ?

isan

@SGaist I cross compile it and copy libQt5Charts.so.2 to qt5pi library on raspberry pi

You forgot the symbolic links. If you run ldd on your application on your target it should show you what is missing.

@SGaist
hello;
I am facing similar problem i followed the same procedure given in https://wiki.qt.io/RaspberryPi2EGLFS i am cross-compiling from ubuntu 16.04 to my RPi. error Unknown module Qt:charts/Qt:quick for virtual keyboard.
can you explain step-wise procedure to solve this error.

@Andrex_Qt Did you build these two modules ?

@SGaist,
hello, i did not build those two modules. is that the only way or is there another way ( you want build your own keypad )?
apologies for late reply..

QtCharts has nothing to do with the virtual keyboard module however, QtQuick is mandatory yes.
