Installing ROS 2 on Windows

This page explains how to install ROS 2 on Windows from a pre-built binary package.

System requirements

As of beta-2 only Windows 10 is supported.

Installing prerequisites

Install Chocolatey

Chocolatey is a package manager for Windows, install it by following their installation instructions:

https://chocolatey.org/

You’ll use Chocolatey to install some other developer tools.

Install Python

Open a Command Prompt and type the following to install Python via Chocolatey:

> choco install -y python

Install OpenSSL

Download an OpenSSL installer from this page. Scroll to the bottom of the page and download Win64 OpenSSL v1.0.2. Don’t download the Win32 or Light versions.

Run the installer with default parameters. Then, define environment variables (the following commands assume you used the default installation directory):

  • setx -m OPENSSL_CONF C:\OpenSSL-Win64\bin\openssl.cfg
  • Add C:\OpenSSL-Win64\bin\ to your PATH

Install Visual Studio

Install Visual Studio 2015 if using Ardent or earlier If you already have a paid version of Visual Studio 2015 (Professional, Enterprise), skip this step. Microsoft provides a free of charge version of Visual Studio 2015, named Community, which can be used to build applications that use ROS 2: https://www.visualstudio.com/vs/older-downloads/ Make sure that the Visual C++ features are installed. First choose 'Custom installation': ![Custom installation](http://i.imgur.com/tUcOMOA.png) Next check Visual C++: ![Visual C++](http://i.imgur.com/yWVEUkm.png) Ensure that the correct features will be installed: ![Summary](http://i.imgur.com/VxdbA7G.png)
Install Visual Studio 2017 if using Bouncy or a nightly If you already have a paid version of Visual Studio 2017 (Professional, Enterprise), skip this step. :warning: Visual Studio 2017 v15.8 seems to have a compiler bug preventing from building some ROS 2 packages. Please try installing an older version of Visual Studio 2017. Microsoft provides a free of charge version of Visual Studio 2017, named Community, which can be used to build applications that use ROS 2: https://visualstudio.microsoft.com/downloads/ Make sure that the Visual C++ features are installed. An easy way to make sure they're installed is to select the `Desktop development with C++` workflow during the install. ![Desktop development With C++](https://i.imgur.com/2h0IxCk.png)

Install additional DDS implementations (optional)

ROS 2 builds on top of DDS. It is compatible with multiple DDS or RTPS (the DDS wire protocol) vendors.

The package you downloaded has been built with optional support for multiple vendors: eProsima FastRTPS, Adlink OpenSplice, and (as of ROS 2 Bouncy) RTI Connext as the middleware options. Run-time support for eProsima’s Fast RTPS is included bundled by default. If you would like to use one of the other vendors you will need to install their software separately.

RTI Connext

To use RTI Connext (available as of ROS 2 Bouncy) you will need to have obtained a license from RTI.

You can install the Windows package of Connext version 5.3.1 provided by RTI from their downloads page.

After installing, run RTI launcher and point it to your license file.

Set the NDDSHOME environment variable:

set "NDDSHOME=C:\Program Files\rti_connext_dds-5.3.1"

If you want to install the Connext DDS-Security plugins please refer to this page

Install OpenCV

Some of the examples require OpenCV to be installed.

You can download a precompiled version of OpenCV 3.4.1 from https://github.com/ros2/ros2/releases/download/opencv-archives/opencv-3.4.1-vc15.VS2017.zip

Assuming you unpacked it to C:\opencv, type the following on a Command Prompt (requires Admin privileges):

setx -m OpenCV_DIR C:\opencv

Since you are using a precompiled ROS version, we have to tell it where to find the OpenCV libraries. You have to extend the PATH variable to c:\opencv\x64\vc15\bin

In ardent and earlier

These releases used OpenCV 2. You can download a precompiled version of OpenCV 2.4.13.2 from https://github.com/ros2/ros2/releases/download/release-beta2/opencv-2.4.13.2-vc14.VS2015.zip

Since you are using a precompiled ROS version, we have to tell it where to find the OpenCV libraries. Assuming you were extracting OpenCV to c:\ you have to extend the PATH variable to c:\opencv-2.4.13.2-vc14.VS2015\x64\vc14\bin

Install dependencies

There are a few dependencies not available in the Chocolatey package database. In order to ease the manual installation process, we provide the necessary Chocolatey packages.

As some chocolatey packages rely on it, we start by installing CMake

> choco install -y cmake

You will need to append the CMake bin folder C:\Program Files\CMake\bin to the PATH (you can do this by clicking the Windows icon, typing “Environment Variables”, then clicking on “Edit the system environment variables”. In the resulting dialog, click “Environment Variables”, the click “Path” on the bottom pane, then click “Edit” and add the path).

Please download these packages from this GitHub repository.

  • asio.1.12.1.nupkg
  • eigen-3.3.4.nupkg
  • tinyxml-usestl.2.6.2.nupkg
  • tinyxml2.6.0.0.nupkg

Once these packages are downloaded, open an administrative shell and execute the following command:

> choco install -y -s <PATH\TO\DOWNLOADS\> asio eigen tinyxml-usestl tinyxml2

Please replace <PATH\TO\DOWNLOADS> with the folder you downloaded the packages to.

You must also install some python dependencies for command-line tools:

python -m pip install -U catkin_pkg empy git+https://github.com/lark-parser/lark.git@0.7b pyparsing pyyaml setuptools

rqt dependencies

python -m pip install -U pydot PyQt5

Downloading ROS 2

  • Go the releases page: https://github.com/ros2/ros2/releases
  • Download the latest package for Windows, e.g., ros2-package-windows-AMD64.zip.
    • Notes:
      • there may be more than one binary download option which might cause the file name to differ.
      • [ROS Bouncy only] To download the ROS 2 debug libraries you’ll need to download ros2-bouncy-windows-Debug-AMD64.zip
  • Unpack the zip file somewhere (we’ll assume C:\dev\ros2).
    • Note (Ardent and earlier): There seems to be an issue where extracting the zip file with 7zip causes RViz to crash on startup. Extract the zip file using the Windows explorer to prevent this.

Set up the ROS 2 environment

Start a command shell and source the ROS 2 setup file to set up the workspace:

> call C:\dev\ros2\local_setup.bat

For ROS 2 releases up to and including Ardent, if you downloaded a release with OpenSplice support you must additionally source the OpenSplice setup file manually (this is done automatically for ROS 2 releases later than Ardent; this step can be skipped). It is normal that the previous command, if nothing else went wrong, outputs “The system cannot find the path specified.” exactly once. Only do this step after you have sourced the ROS 2 setup file:

> call "C:\opensplice67\HDE\x86_64.win64\release.bat"

Try some examples

In a command shell, set up the ROS 2 environment as described above and then run a talker:

> ros2 run demo_nodes_cpp talker

Start another command shell and run a listener:

> ros2 run demo_nodes_py listener

You should see the talker saying that it’s Publishing messages and the listener saying I heard those messages. Hooray!

If you have installed support for an optional vendor, see this page for details on how to use that vendor.

Troubleshooting

  • If at one point your example would not start because of missing dll’s, please verify that all libraries from external dependencies such as OpenCV are located inside your PATH variable.
  • If you forget to call the local_setup.bat file from your terminal, the demo programs will most likely crash immediately.
