Note this error message, which is repeated a few times:

/home/christophe.bedard/ros2_ws/install/zenoh_cpp_vendor/opt/zenoh_cpp_vendor/include/zenoh/api/shm/buffer/zshm.hxx:69:25: error: ‘ref’ is not a member of ‘std’

It seems like something in zenoh uses std::ref without including <functional>. Including <functional> in some locations before <zenoh.hxx> is included fixes the build:

Note that <zenoh.hxx> is sometimes included before the STL includes. For example, see zenoh_utils.hpp. In any case, this should probably instead be fixed in zenoh.

Interestingly, we didn't see this because it doesn't fail on Ubuntu 24.04 for whatever reason. Regardless, as I wrote in #351 (comment) , we should fix this in upstream zenoh-cpp.

Thanks, @ahcorde and @christophebedard! The PR looks good to me. By the way, I did a test within Iron and Humble dockers (22.04). It surprised me that it passed in Humble but failed in Iron.
