That error isn't about dlib. It means something is terribly wrong with your compiler. I also use dlib on ubuntu all the time without issue. If you can post complete instructions to replicate this error on ubuntu I'll look into it. But you need to post what exactly someone types, starting from a standard ubuntu install.

Today，I reinstalled dlib on the system of Ubuntu 14.04 with python3.6 and it succeeded.
I think the Error may be related to python3.5。

ananconda3,
python3.5

@QuantumLiu
I encountered this problem again.
run: conda install libgcc
can solve this problem.
