Cannot Run Project in Eclipse C/C++ OpenCV 2.4.5 Ubuntu 12.10

Question

I have just installed OpenCV 2.4.5 and Eclipse IDE for C/C++ Developers on Ubuntu 12.10 and followed this opencv.org tutorial. The project builds with no errors but when I reach the "Running the executable" section from Eclipse, I get the following message after hitting Run:

/home/pedro/workspace/di/Debug/di: error while loading shared libraries: libopencv_core.so.2.4: cannot open shared object file: No such file or directory

Does anyone have any suggestions on how to solve this issue?

EDIT:

Using sudo dpkg -l | grep opencv gives:

Sorry the formatting is not the best.

The command "locate libopencv_core"

• /usr/lib/libopencv_core.a
• /usr/lib/libopencv_core.so
• /usr/lib/libopencv_core.so.2.3
• /usr/lib/libopencv_core.so.2

"locate libopencv" shows a extensive list that I don't know if it would be appropriate to copy it.

Ubuntu Quency Quantal 12.10 has 2.3.1 packages in it's repo: OpenCV in Ubuntu 12.10 repo The next version, raring has 2.4. I'd uninstall Ubuntu 12.10's various v2.3.1 opencv related packages. (How did they got installed? Did you install them manually, or something pulled them in?). Then I'd try to compile+install the OpenCV source again. The install stage of the make procedure should provide libraries to you.
