Hi, I am using a jetson nano with a dusty-nv docker for ros2 humble. I tried to install it from command as “sudo apt install ros-humble-filters” and didn’t worked so I tried to install it from source. When builiding it I have this error.

Hope you can help me.

Hi @thiagoromero42, can you try cloning the ros2 branch of that repo instead?

Or here is a way that you can pull/build ROS packages from source using rosinstall_generator or rosdep:

github.com

dusty-nv/jetbot_ros/blob/d8e5ee1b17f5c66d038017b86f8920a496197ea9/Dockerfile#L72


      
              pip3 install protobuf>=2.6 --verbose && \

              pip3 install trollius --verbose && \

              pip3 install pynput --verbose

          

          ENV PYTHONPATH=/opt/py3gazebo

             

             

          #

          # Gazebo plugins for ROS

          #

          RUN source ${ROS_ROOT}/install/setup.bash && \

              export ROS_PACKAGE_PATH=${AMENT_PREFIX_PATH} && \

              cd ${ROS_ROOT} && \

              mkdir -p src/gazebo && \

              rosinstall_generator --deps --exclude RPP --rosdistro ${ROS_DISTRO} \

                    gazebo_ros_pkgs \

          	> ros2.${ROS_DISTRO}.gazebo.rosinstall && \

              cat ros2.${ROS_DISTRO}.gazebo.rosinstall && \

              vcs import src/gazebo < ros2.${ROS_DISTRO}.gazebo.rosinstall && \

              apt-get update && \

              rosdep install -y \

(replace gazebo_ros_pkgs with the ROS package names that you want)
