Answer 1

So, I solved this problem with the answer from Peter Korsgaard. Bassicly I removed my old bluetooth version, installed the new version which supports QtCharts ( https://buildroot.org/downloads/buildroot-2018.02-rc1.tar.gz ), and now my application is running. Problems found: Had the change the content of my cmdline.txt and config.txt because they were making the new version crash in boot and give "Kernel Panic". I just used the default cmdline.txt and config.txt generated by make, and now its running.

Answer 2

On Ubuntu 18.04, installing libqt5charts5-dev (as suggested by eyllanesc) using Synaptic Package Manager solved my issue. Version: Qt Creator 4.5.2 based on Qt 5.9.5.
