Compatibility between opendds and cyclonedds

[Yingliangzhe]

Hello everyone,
I have a question about the compartibility of opendds as mentioned in title.
If I would like to write a publisher in opendds and a subscriber in cyclone. Would it be possible, that the subscriber receives the messages from the publisher, which is writen in opendds? Have you already tested the compartibility?

rmw_opendds is still in development. We have tried the ROS2 system tests with Fast RTPS and doing the same with Cyclone should be possible. Please let us know what you find out.

OpenDDS itself conforms to the OMG DDS specifications and should have no problem working with Cyclone assuming it does the same.

Is there a readme file, which can guide me to build the rmw_opendds? I already have the ros2 framework on my pc, and checked the interoperability between Fast RTPS and zenoh bridge(implemented using cyclonedds).
Within the docker the publisher through rmw_opendds was not found. I would like to try it without docker.
Thank you
