Request for Cyclone DDS loaned message working example

I've tried Galactic, Rolling, and building cyclone DDS and iceoryx from source using instructions at:

https://github.com/ApexAI/rmw_cyclone... https://github.com/eclipse-cyclonedds...

No matter what I do, I always get this error message when I try to borrow a loaned message:

Currently used middleware can't loan messages. Local allocator will be used.

Tests show large latencies that grow with message size.

I understand that for shared memory / zero-copy to work the data must be POD and certain QoS settings must be used. I've tried a lot of different options with no success.

Does someone have a working example with source code and configuration files?

Hi, since this feature is still in an experimental stage, it is disabled by default but can be enabled easily by providing a cyclonedds.xml configuration file: https://github.com/ros2/rmw_cyclonedd...
