OS: ubuntu 18.04.01 Install packages: sudo apt-get install qt5-default libqt5serialport5-dev build-essential libgtk2.0-dev libusb-1.0-0-dev libnotify-dev libudev-dev libappindicator-dev git ... get the error during compilation:

Is it the way to fix it?

Just need to add QDataStream header as above to qtlocalpeer.cpp.
