N1SDP bitbake error

Hi, I was following 


I think I exactly followed it (on my ubuntu 16.04, I had to install python 3.6 from source with sqlite support and gcc 6.0 ).

Not at the final bitmake command, I get following error. Can anyone help me please?

(I asked support@arm too so I might get answer from there and will post it here.)
