This guide shows you how to install and use the tool with the most common configuration. For advanced options and complete reference information, see the official documentation. Some install guides also include optional next steps to help you explore related workflows or integrations.

The [Eclipse Cyclone DDS](https://cyclonedds.io/) is an open-source implementation of the Data Distribution Service ([DDS](https://en.wikipedia.org/wiki/Data_Distribution_Service)) standard, designed for high-performance, real-time, and scalable communication in autonomous systems, robotics, industrial IoT, and aerospace applications.

It is part of the Eclipse Foundation and is widely used in Robotic Operating System (ROS) 2 as a key middleware framework for inter-process communication.

## Before you begin

This article provides a quick solution to install Cyclone DDS on Arm Linux.

Confirm you are using an Arm Linux machine by running:

```bash
uname -m
```

The output should be:

```
__output__ aarch64
```

If you see a different result, you are not using an Arm computer running 64-bit Linux.

You need to install the following before building Cyclone DDS:

- C and C++ compilers (such as GCC).
- Git.
- CMake see [How do I install CMake?](/install-guides/cmake/).
- OpenSSL.

For Ubuntu Linux, run the commands below. For other Linux distributions, use the package manager to install the software listed above.

```bash
sudo apt update
sudo apt install -y gcc g++ git cmake libssl-dev
```

## How do I build Cyclone DDS?

You can install Cyclone DDS by building the source code.

Clone the GitHub repository to create a build folder:

```bash
cd $HOME
git clone https://github.com/eclipse-cyclonedds/cyclonedds.git
```

Once downloaded, you can build and install Cyclone DDS.

Enable the flags `BUILD_EXAMPLES` (to compile the example applications included) and `BUILD_TESTING` (to compile the test suite).

Here are the build and install commands:

```bash
cd cyclonedds
mkdir build && cd build
cmake -DBUILD_EXAMPLES=ON -DBUILD_TESTING=ON ..
cmake --build .
sudo cmake --build . --target install
```

Cyclone DDS is now installed in `/usr/local`.

> **Note**  
> If you don’t want to install Cyclone DDS in the default location of `/usr/local`, you can specify another location by adding `-DCMAKE_INSTALL_PREFIX=<install-prefix>` to the first `cmake` command with your alternative location.

## How can I test Cyclone DDS?

To verify the installation, you can run the `Hello World` example from the build directory.

Open two terminals and navigate to the `bin/` directory in each.

Run the commands shown below in each tab in each of your two terminals:

```bash
cd $HOME/cyclonedds/build/bin/
./HelloworldPublisher
```

```bash
cd $HOME/cyclonedds/build/bin/
./HelloworldSubscriber
```

If you observe the following output from each of the terminals, Cyclone DDS is running correctly on your Arm Linux machine.

```bash
=== [Publisher]  Waiting for a reader to be discovered ...
=== [Publisher]  Writing : Message (1, Hello World)
```

```bash
=== [Subscriber] Waiting for a sample ...
=== [Subscriber] Received : Message (1, Hello World)
```

You are now ready to use Cyclone DDS.
