Error installing ROS on RPI 3B+

edit

I am trying to folow this guide to install ROS on a Raspberry Pi 3 B+ with Debian-Stretch and at 4.1 point I need to folow this guide where I managed to reach the 3.2 Rebuild your workspace point. This is the point where I get this error:

<== Failed to process package 'pluginlib': 
  Command '['/home/pi/ros_catkin_ws/devel_isolated/rosconsole/env.sh', 'cmake', '/home/pi/ros_catkin_ws/src/pluginlib', '-DCATKIN_DEVEL_PREFIX=/home/pi/ros_catkin_ws/devel_isolated/pluginlib', '-DCMAKE_INSTALL_PREFIX=/opt/ros/kinetic', '-G', 'Unix Makefiles']' returned non-zero exit status 1

Reproduce this error by running:
==> cd /home/pi/ros_catkin_ws/build_isolated/pluginlib && /home/pi/ros_catkin_ws/devel_isolated/rosconsole/env.sh cmake /home/pi/ros_catkin_ws/src/pluginlib -DCATKIN_DEVEL_PREFIX=/home/pi/ros_catkin_ws/devel_isolated/pluginlib -DCMAKE_INSTALL_PREFIX=/opt/ros/kinetic -G 'Unix Makefiles'

Command failed, exiting.

Before this error I got another 2-3 errors that I managed to resolve but this is beyond my power.
