Question

I am trying to build the QGroundControl for Android with the QT, but I am getting the below error: error: Unknown module(s) in QT: charts

I can build the QGroundControl for Windows without any trouble.

Answer 1

you have to add

QT += charts

in your .pro file.

If you want to use charts just in android use

android: QT += charts
