ament_tools is missing

[azazdeaz]

The build_ros2.bash is using ament_tools which was removed from ros2.repos

I tried both adding ament_tools manually and migrating to colcon but i kept running into errors (i'm very new to these things :) ).

Hi azazdeaz,

Do you managed to using colcon on rasberry ? I have your same problem.

I ran into the same issue, and I was able to get a little further by apply these fixes (at least until trying to compile fastrtps due to missing dependencies):

1. Clone ament_tools into ~/ros2_rpi/ros2_ws/src/ament
2. Edit Dockerfile.bootstrap by adding from Start to End below:

   .
   .
   .
   python3-pkg-resources \
   python3-setuptools \
   python3-pyparsing \
   qemu-user-static \
   software-properties-common
   # <-- Start
   RUN easy_install3 pip
   RUN python3 -m pip install catkin_pkg
   RUN python3 -m pip install rosdep rosinstall_generator wstool rosinstall six vctsools
   RUN rosdep init
   RUN rosdep update
   # --> End
   .
   .
   .

However, when building fastrtps I still get this error:

+++ Building 'fastrtps'
==> '. /ros2_ws/build/fastrtps/cmake__build.sh && /usr/bin/cmake -DBUILD_TESTING=0 -DCMAKE_INSTALL_PREFIX=/ros2_ws/install /ros2_ws/src/eProsima/Fast-RTPS' in '/ros2_ws/build/fastrtps'

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

I was under the impression that rosdep should install all of the libraries required, but perhaps the path is missing in the bootstrap file? I don't really know enough about docker, rosdep or this tool to know where to look for the missing packages in the docker container.

I've managed to build ROS2 after changing the build tool to colcon and also switched to ros2 version crystal. The changes currently reside in my own fork /avrabe/ros2_raspbian_tools.

With these changes I was able to build (not test yet) ROS2 without rviz, ros-visualization and the demos. For the details on how to build, the circleci config .circleci/config.yml is the most accurate description.
