@Pedestrian1671022 there is not enough information in the description. Please fill out the issue template when submitting an issue. Formatting the code and console output is also appreciated.
We encourage you to ask debugging question on ROS Answers and open issues on Github only when confirmed that there is a bug in the code.

If I had to guess I'd say that you are building custom packages using the latest API from master but using ardent packages for your dependencies. The addition of rmw_log_severity_t happened after the Ardent release so is not part of the binary packages.

You can either try to build from source or use the ardent branch of the repositories you are modifying the sources.

I'm closing this, feel free to post a new question on ROS answers following our support guidelines if you still face problems compiling
