Have rosdep installed.

Install packages

The easiest way is to install from ROS 2 apt repository.

sudo apt install ros-rolling-rmw-cyclonedds-cpp

Build from source code

Building from source code is also another way to install.

First, clone Cyclone DDS and rmw_cyclonedds in the ROS 2 workspace source directory.

cd ros2_ws/src
git clone ros2/rmw_cyclonedds -b rolling
git clone eclipse-cyclonedds/cyclonedds

Then, install necessary packages for Cyclone DDS.

cd ..
rosdep install --from src -i

Finally, run colcon build.

colcon build --symlink-install

Switch to rmw_cyclonedds

Switch from other rmw to rmw_cyclonedds by specifying the environment variable.

export RMW_IMPLEMENTATION=rmw_cyclonedds_cpp

Run the talker and listener

Now run talker and listener to test Cyclone DDS.

ros2 run demo_nodes_cpp talker
ros2 run demo_nodes_cpp listener
