Compiling o3d3xx-ros

It appears as though you have both OpenCV 3 and OpenCV 2.4 installed on your system. Since you are using ROS Indigo and you want to build our ROS bindings, you will need to settle on using OpenCV 2.4. I.e., you cannot link to two different versions of OpenCV in the same binary. From the above output, it looks like when you built libo3d3xx's image module you linked to OpenCV 3. When building the image module of libo3d3xx you can specify the -DFORCE_OPENCV2=ON flag to ensure you are building against OpenCV 2.4. Please note, this will require you to not use the top-level build system in libo3d3xx but rather build each module individually.

An unrelated note, but worth bringing up.... if you are just getting started with the ifm O3 cameras, I'd suggest you consider using the newer libraries: ifm3d and ifm3d-ros.

Hi Tom,
Thanks a lot for help. The issue now is resolved, as following:
1- I found references to opencv 3 (was installed from source) and removed it using sudo make uninstall. And deleted the previous 'build' folders from each modules and the libo3d3xx.
2- I rebuild the individual modules, camera, framegrabber
3- build the image module with -DFORCE_OPENCV2=ON flag
4- build the top-level library with camera connected. (at first (i.e., before deleting the 'build' folders and rebuild again with -DFORCE_OPENCV2=ON for image module), the catkin_make failed as libopencv_core.so.3 says missing and still needed by libo3d3xx). resolved when I started again by deleting the 'build' folders.
5- catkin_make my workspace
All Tests are passed. and now I can start rviz and view the data.

Thanks again
Wissam
