Build from source code

cd ros2_ws/src git clone https://github.com/ros2/rmw_gurumdds ros2/rmw_gurumdds git clone https://github.com/ros2/rosidl_typesupport_gurumdds ros2/rosidl_typesupport_gurumdds
Then, install necessary packages for GurumDDS.
cd .. rosdep install --from src -i --rosdistro galactic
Finally, run colcon build.
colcon build --symlink-install
