Revision history [back]

My system info:

Ubuntu 14.04.3 LTS
OpenCV 2.4.13
ROS Jade

I have the same link error but fix by switching the following content in CMakeLists.txt

${OpenCV_LIBRARIES} ${catkin_LIBRARIES} in target_link_libraries
${OpenCV_INCLUDE_DIRS} ${catkin_INCLUDE_DIRS} in include_directories

OpenCV first, then catkin.

Hopefully this approach can resolve your problem.
