I wanted to build firmware according to the getting started guide (
http://www.8devices.com/wiki/carambola:2:gettingstarted)
But building it fails all the time.
I am using Ubuntu 18.04.1 LTS on a virtual machine (Virtual box from oracle)
Error output after entering the command "make -j1 V=s":

Do you have any suggestions on how to solve this problem?
