How to resolve opencv multiple ver conflicts while building ORB-SLAM2?
Hi I am trying to check out orb2SLAM . When I try to build the package . I get the following error
/usr/bin/ld: warning: libopencv_core.so.4.3, needed by /home/shyam/AMR-II/catkin_ws/src/orb_slam_2_ros/orb_slam2/lib/liborb_slam2_ros.so, may conflict with libopencv_core.so.3.2
/usr/bin/ld: warning: libopencv_imgcodecs.so.3.2, needed by /opt/ros/melodic/lib/libcv_bridge.so, may conflict with libopencv_imgcodecs.so.4.3

Hi.
These are warning, not errors. Did you try to run Orbslam after built?

A simple solution is to download a suitable version of vision_opencv from https://github.com/ros-perception/vision_opencv/releases. Then extract the contents (containing some packages cv_bridge image_geometry opencv_tests vision_opencv) to a folder called vision_opencv of your src folder in your catkin workspace.
Now catkin_make or catkin build your workspace and the necessary ros opencv packages will compile and link against the local vision_opencv folder. You might need to clean your workspace before that.
