Can't get opencv to work with eclipse mars (ubuntu 15.10)

edit

Hello,

I am running Ubuntu 15.10 and installed the current version of Eclipse Mars from eclipse.org. Then I installed the latest version of opencv from the git repository and tried to set up the project described in this tutorial. I followed the tutorial step by step but when I try to build it, I receive the following errors:

My libs are in /usr/local/libs and my includes in /usr/local/include/opencv and I inserted these paths in the project properties just as described in the tutorial.

What am I doing wrong? I already suceeded to run opencv in VisualStudio in Windows 10 and in XCode in Mac OS X. But with Eclipse in Ubuntu it won't work.
