Thank you for creating your first issue on this repo! Give me some time to review and respond to your problem.
Hi all,
my bad. Given the above structure, you must first install the dependencies using
cd $myworkspace
rosdep install --from-paths src -i
and the error is gone (trivial, yet might be worth adding to the readme).
cd $myworkspace
source /opt/ros/foxy/setup.bash
colcon build --packages-select bno055
source install/local_setup.bash
ros2 run bno055 bno055 --ros-args --params-file ./src/bno055/bno055/params/bno055_params.yaml
now results in

UPDATE: it works fine on my desktop.
Ok. Now, based on this ROS2 Git Issue one should run
apt-get dist-upgrade
which fixed the error! Thank you for reading everybody, I hope it helpes someone else in the future.
Hey,
given the following structure on my Raspberry Pi 4b running Ubuntu 20.04 Server
and
gives me the following error
Could someone replicate the error? Any advice?
example_interfaces
is a standard ROS2 package given by the ROS2 developers, e.g. used in their tutorials, too: see Writing A Simple Py Service And Client.The
bno055/package.xml
looks fine, including as<exec_depend>example_interfaces</exec_depend>
, which I would normally do as<depend>example_interfaces</depend>
, but colcon says it's redundant.
