on windows, rmw_cyclonedds is failing with,

C:\ci\ws\src\ros2\rmw_cyclonedds\rmw_cyclonedds_cpp\src\bytewise.hpp(32,12): error C2371: 'byte': redefinition; different basic types (compiling source file C:\ci\ws\src\ros2\rmw_cyclonedds\rmw_cyclonedds_cpp\src\rmw_node.cpp) [C:\ci\ws\build\rmw_cyclonedds_cpp\rmw_cyclonedds_cpp.vcxproj]

i am not sure why this is happening, before diving into the details i would like to retry just once again.

• Windows

[ahcorde]

@fujitatomoya This PR ros2/rcutils#492 should fix the windows regression

[ahcorde]

Windows warning is unrelated

[fujitatomoya]

i am writing documentation about this. this feature is supported from Humble, to keep the documentation consistent between all released distro, i would like to backport this example.

[fujitatomoya]

@Mergifyio backport humble jazzy

[mergify]

backport humble jazzy

Looks like this PR introduced a flake8 regression. The CI job reported a success despite the logs having an error: https://ci.ros2.org/job/ci_linux/22905/console. This also happened in ros2/rosbag2#1946 (comment).

[fujitatomoya]

@Yadunund this PR does not touch anything ros2/demos#712 trying to fix???

maybe #407 (comment) should have been posted on ros2/demos#711?

[Yadunund]

@fujitatomoya a CI job I ran for a different PR flagged a test error for examples_rclpy_minimal_publisher: https://ci.ros2.org/job/ci_linux/22914/testReport/junit/examples_rclpy_minimal_publisher.topics.minimal_publisher.test/test_flake8/test_flake8/

And when i look at the console logs for the job Alex ran above, I do see the flake8 failure but somehow the CI job was reported as success: https://ci.ros2.org/job/ci_linux/22905/console

[fujitatomoya]

@Yadunund

Ah, sorry i was mixed up, my bad.

now i see flake8 error with backports. i will fix it up.

[fujitatomoya]

@ahcorde thank you very much for taking care of this and backports.
