OpenDDS
OpenDDS 3.30.0
OpenDDS is an open-source C++ implementation of the Object Management Group's specification "Data Distribution Service for Real-time Systems" (DDS), as well as some other related specifications. These standards define a set of interfaces and protocols for developing distributed applications based on the publish-subscribe and distributed cache models. Although OpenDDS is itself developed in C++, Java bindings are provided so that Java applications can use OpenDDS. OpenDDS also includes support for the DDS Security and XTypes specifications.
OpenDDS is built on the ACE abstraction layer to provide platform portability. OpenDDS also leverages the capabilities of TAO for IDL compilation and the OpenDDS DCPS Information Repository.
The primary development of OpenDDS was done by
Object Computing, Incorporated in
St. Louis and Phoenix. It is released under generous license
terms similar to ACE, TAO and MPC. See the LICENSE file for
details.

Questions concerning OpenDDS should be directed to GitHub Discussions.
If you wish to file a bug report:
tests/DCPS/MyExample (MyExample is a placeholder.)run_test.pl. Be sure to document the options. See tests/DCPS/HelloWorld/run_test.pl for inspiration.README.rst file that gives a high-level overview of the example and the problem that it illustrates.It should be possible to build and run the example using run_test.pl as in the quickstarts for Windows and Linux.
If the problem lies in the example, then GitHub's Pull Request interface will allow people to discuss, comment on, and propose changes to get the example working.
If the problem lies in OpenDDS, then the example is a new test case.
This release of OpenDDS is based on the DDS Specification formal/2015-04-10 (version 1.4). It features the following transport protocols:
RTPS (Interoperability) features are based on the DDS-RTPS Specification formal/2019-04-03 (version 2.3). See the OpenDDS Developer's Guide and the file docs/design/RTPS for more details on RTPS.
See the Developer's Guide for information on OpenDDS compliance with the DDS specification. If you would like to contribute a feature or sponsor the developers to add a feature please see the Support section above for contact information.
These are just the required dependencies. For a complete detailed list of dependencies, including optional ones, see https://opendds.readthedocs.io/en/latest-release/devguide/building/dependencies.html.
OpenDDS requires TAO for both IDL compilation as well as interaction with the
DCPSInfoRepo. ACE is also required, but it is always included with TAO. If you
will be using the configure script for OpenDDS, you do not need to download TAO
first -- the configure script will download it for you.
Perl is used for the configure script, running the automated tests and examples included in this source tree, and generating Makefiles or Visual Studio project files.
On Windows we recommend the use of Strawberry Perl.
This release of OpenDDS has been tested under the following platforms:
Linux family:
Windows family:
Embedded/Mobile/IoT:
We have built OpenDDS for VxWorks 6.9, 7, and 21.03 and have run basic system and performance tests (but not the entire regression test suite). Please see the OpenDDS Support page for more information on support for ACE, TAO, and OpenDDS on VxWorks. Download VxWorks RPM packages for ACE, TAO, and OpenDDS here.
This release of OpenDDS has been tested using the following compilers:
For building and installation instructions see https://opendds.readthedocs.io/en/latest-release/devguide/building/index.html
See the Docker Quick Start for how to use the pre-built docker image.
