 While DDS support in Ardupilot is mostly through git submodules, another tool needs to be available on your system: Micro XRCE DDS Gen.

+Follow the wiki [here](https://ardupilot.org/dev/docs/ros2.html#installation-ubuntu) to set up your environment.
-- Install java
-  ```console
-  sudo apt install default-jre
-  ````
-- Follow instructions [here](https://micro-xrce-dds.docs.eprosima.com/en/latest/installation.html#installing-the-micro-xrce-dds-gen-tool) to install the latest version of the generator using Ardupilot's mirror

-> :warning: **If you have installed FastDDS or FastDDSGen globally on your system**:
-eProsima's libraries and the packaging system in Ardupilot are not deterministic in this scenario.
-You may experience the wrong version of a library brought in, or runtime segfaults.
-For now, avoid having simultaneous local and global installs.
-If you followed the [global install](https://fast-dds.docs.eprosima.com/en/latest/installation/sources/sources_linux.html#global-installation)
-section, you should remove it and switch to local install.
 
 ### Serial Only: Set up serial for SITL with DDS
