Skip OpenCV in ROS Kinetic install?
I'm trying to install ROS Kinetic on my Raspberry Pi 4 (4gb) running Rasbian Buster. It fails every time when it gets to installing OpenCV. Is there a way I skip OpenCV during the ROS install? The error I get is the following:
It's the same issue seen here: https://www.raspberrypi.org/forums/viewtopic.php?t=245432.
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: *** [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.

Hello,
For installing ROS on raspberry, you should follow this tutorial : http://wiki.ros.org/ROSberryPi/Installing%20ROS%20Kinetic%20on%20the%20Raspberry%20Pi
The main this to do is to use ROS-base or ROS-Comm (ros-kinetic-base or ros-kinetic-core) when installing ROS as it do not have any graphical dependencies : https://www.ros.org/reps/rep-0142.html#ros-core

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:

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/.

tl;dr Solution is https://github.com/opencv/opencv/issues/14856
If you follow the instruction to rebuild it (although you might need to cd /home/pi/ros_catkin_ws/build_isolated/opencv3/install - not just "/opencv3"), and if you make the terminal rollback long enough, you can see the actual error message, which is the same as that mentioned in the link above.
