It worked on 2.4 (this is really old project)

[likezjuisee]

I have tried 2.4.0 and 2.4.13, both failed.
Could you give me the specific version?

[MichalBusta]

I can compile it now on Ubuntu 18.04
Using OpenCV from /usr/share/OpenCV, include dirs: /usr/include;/usr/include/opencv 3
exact version is 3.2.0
