You're reading the documentation for an older, but still supported, version of ROS 2. For information on the latest version, please have a look at Humble.

GurumNetworks GurumDDS

rmw_gurumdds is a implementation of the ROS middleware interface using GurumNetworks GurumDDS. More information about GurumDDS is available on our website:


The following description assumes that you have completed the ‘Environment setup’ process from the Installing ROS 2 via Debian Packages or from the Building ROS 2 on Ubuntu Linux.

rmw_gurumdds requires version of GurumDDS-2.7.x. Debian packages of GurumDDS is provided in the ROS 2 apt repositories on linux. Windows binary installer of GurumDDS will be supported soon.

GurumDDS requires a license. See the next page: After getting a license, move it to the following location.

Install packages

The easiest way is to install from ROS 2 apt repository. When ros-galactic-rmw-gurumdds-cpp is installed, gurumdds-2.7 is also installed.

sudo apt install ros-galactic-rmw-gurumdds-cpp

Build from source code

Building from source code is also another way to install.

First, clone rosidl_typesupport_gurumdds and rmw_gurumdds in the ROS 2 workspace source directory.

cd ros2_ws/src
git clone ros2/rmw_gurumdds
git clone 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

Switch to rmw_gurumdds

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

export RMW_IMPLEMENTATION=rmw_gurumdds_cpp

Run the talker and listener

Now run talker and listener to test GurumDDS. Don’t forget to set up environment by setup script.

ros2 run demo_nodes_cpp talker
ros2 run demo_nodes_cpp listener
