(VOXL2 PX4 ROS2) px4_msgs Unrecognized In Program

[GlennTee]

Hello. I'm attempting to use various PX4 messages in a program I am working on, but for some reason the px4_msgs package is not recognized at all. I'm not sure if it is a path issue or if I downloaded it wrong somehow, but I tried sourcing the files and that hasn't worked. Ignoring the type also hasn't worked for me. Is there any easy fix for this that I'm missing? I am urgently seeking a fix for this. Pictured below is the error that comes up:

@GlennTee have you sourced the right directories? If you run source /opt/ros/foxy/mpa_to_ros/install/setup.bash that should tell your package manager that the px4 messages type exists. I also notice you are running this on your local machine - have you install the necessary packages there? If you instantiate the voxl-cross or qrb5165 emulator image and then use vscode inside the docker then you should be able to see the px4 messages just fine.

LMK if that helps!

@Zachary-Lowell-0 I tried "source /opt/ros/foxy/setup.bash" and "source install/local_setup.bash," but this was for trying to run my program. I just tried running "source /opt/ros/foxy/mpa_to_ros/install/setup.bash" and this is what I got:

I'm using remote ssh in order to access the files on the drone.

Did you ever install voxl-ros2-foxy?

@Zachary-Lowell-0 Yes I installed voxl-ros2-foxy. This time I just tried "source /opt/ros/foxy/mpa_to_ros2/install/setup.bash" and that was accepted. However, looking now px4_msgs is still not recognized within my program.
