i exec "sudo find / -name features.h" there no features.h in rmw dir, anyone knows?

[clalancette]

Which ROS 2 distribution are you using? You can only compile the head of this repository if you are using Rolling.

[fengtuo58]

@clalancette galactic

[fengtuo58]

I flollow this url（https://docs.ros.org/en/galactic/Installation/DDS-Implementations/Working-with-Eclipse-CycloneDDS.html) to build from source code

[clalancette]

Yeah, for Galactic you need to use the galactic branch to compile. Otherwise it won't work.

Separately, we should update that documentation page to point to the correct branch. I'll open a PR to do that.

[clalancette]

See https://github.com/ros2/ros2_documentation/pull/2721 .
