Hello agurz,

I clone your code and compile on ubuntu16.0.4, it always report errors. Do you know how to resolve this error? thanks for your kindly help!

Hey @nickwwww, sorry for delay, I was busy with work and exams.

I was able to reproduce the error on a fresh Ubuntu 16.04 installation. I just fixed it, please let me know if it works for you.
