This uses a fixed gcc version, 10.2, as that is what ardupilot is using, and seems to play along fine with glibc and gdbserver in blueos.
10.3 WILL NOT WORK IN BLUEOS

Long and love-rate (more rate than love) relationship, take mostly of this review with a grant of salt.
ROS (started in 2010) have some great tools visualize topics, send and debug messages, check frequencies, and much more. It's also possible to use more advanced tools and solutions like: rviz, gmapping, rtabmap, stereo_image_proc and the list goes on. With ROS, it's possible to take advantage of all drivers that exist for different pieces of hardware. Keep in mind that this is possible, but not easy, usually the drivers need specific configuration, custom settings and may give as output really complex data that needs to be processed or analyzed by another program.

Sometimes it seems like the first (and sometimes only) advice you get offered for almost any problem with a Raspberry Pi is "check your power supply". You think something like:
"hey, I'm using an official power supply sold as being matched with my Pi so how can there be any problem?"
You look up the specs then stick a controlled load across your supply and confirm that it can deliver the required number of Watts.
Yet your problems persist…
