I have the current folder structure here
where msg containts all the .msg files (as seen in px4_msgs github). I'm trying to add the PX4 messages to my matlab to incorporate it into a SitL loop for a quadrotor, but I'm receiving the following error:
But the msg folder clearly contains all the correct .msg files, so I'm not sure why this is having this error. Is there another step I need to add here?

I would double check that the msg directory contains *.msg files

Hi,
You can try the following workarounds:
  1. Double check your path actually contains .msg files and the folder containing those files should be named "msg" only so you can check for any whitespaces, etc.
  2. You can try putting the actual folder path in the "ros2genmsg" command.
  3. You can try going level 1 or 2 up in the folderpath, so instead of "...work/ros2_ws/src/px4_msgs" you can try "...work/ros2_ws/src" or "...work/ros2_ws/src/ros2_ws"
  4. If the above doesn't work then you can try a known bug fix as below, although the error message suggests something else but with the limited information provided, these are the only ways to debug the issue.
Refer to this MATLAB answer for the bug fix: https://www.mathworks.com/matlabcentral/answers/2042607-error-using-ros2genmsg-custom
Here is also a list of other MATLAB answers that you can refer if your issue persists futher: https://www.mathworks.com/support/search.html?c%5B%5D=support&q=ros2genmsg&page=1
