Skip OpenCV in ROS Kinetic install?

edit

That's exactly the installation guide I was using. I've tried multiple times and it fails at the OpenCV part which is why I would like to install without OpenCV if possible. It's the same issue seen here:

https://www.raspberrypi.org/forums/vi....

The error is:

^~~~~~~~~~~~~~~~~~~~~~~~~~ make[2]: * [modules/python3/CMakeFiles/opencv_python3.dir/build.make:63: modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.o] Error 1 make[1]: [CMakeFiles/Makefile2:8425: modules/python3/CMakeFiles/opencv_python3.dir/all] Error 2 make: ** [Makefile:163: all] Error 2 <== Failed to process package 'opencv3': Command '['/opt/ros/kinetic/env.sh', 'make', '-j1']' returned non-zero exit status 2

Reproduce this error by running: ==> cd /home/pi/ros_catkin_ws/build_isolated/opencv3 && /opt/ros/kinetic/env.sh make -j1

Command failed, exiting.

Can you look at the output of the command cat *.rosinstall | grep opencv in your ros_catkin_ws ? there should not be any mention of "opencv3" if you installed ros_comm.

If there is a opencv3 package mention, make sure to redo the step 3 of the installation by creating a new workspace and use :

rosinstall_generator ros_comm --rosdistro kinetic --deps --wet-only --tar > kinetic-ros_comm-wet.rosinstall

wstool init src kinetic-ros_comm-wet.rosinstall

If there is no opencv3 mention, you can try to delete the package ros_catkin_ws/src/opencv3 and ros_catkin_ws/src/vision_opencv, but it would be better to create a new workspace with a clean src/.
