Can u try `rapth` option Use -rpath option. In Eclipse CDT, right click on "DisplayImage" project -> Properties -> C/C++ Build -> Settings -> Tool Settings -> C Linker -> Miscellaneous -> Other options and Add `-rpath "path to libopencv_core.so.3.0" or easier set LD_LIBRARY_PATH=path to so folder – kiranpradeep Jan 15 '15 at 06:42

You are trying to run in Eclipse so the solution provided (The export part) in openCV program compile error "libopencv_core.so.2.4: cannot open shared object file: No such file or directory" in ubuntu 12.04 May not work. I suppose you have installed open cv following the instructions provided in open cv documentation. If so, you can get rid of this problem by adding the following environment variables to the eclipse runtime.
Name - LD_LIBRARY_PATH
Value - $LD_LIBRARY_PATH:/usr/local/lib
Steps
- Click on Run As -> Run Configurations
On the window on the right hand side you see the Environment tab.
Here click on New, you'll see a New Environment Variable pop up.
- Here, for Name enter LD_LIBRARY_PATH, for Value enter $LD_LIBRARY_PATH:/usr/local/lib. click ok and Apply
- Now run again, you shouldn't see the issue.
