The package [rosidl_generator_dds_idl](https://github.com/ros2/rosidl_dds/tree/master/rosidl_generator_dds_idl) already generates `.idl` files from `.msg` files which is being used for `rmw_connext_cpp` and `rmw_fastrtps_cpp`. But `rmw_fastrtps_cpp` is different since it uses introspection rather than generated code specific to each message so for FastRTPS you don't have to generate `.idl` files. --- [Visit Topic](https://discourse.ros.org/t/generate-idl-files-for-fast-rtps-from-ros2-messages/2964/2) or reply to this email to respond.
