Relevant Log Output
See Description above.
So the docker build were really not supposed to be used on mendel (the dev board). The whole point of using docker is so that we can consistently cross compile this example on your robust machine with cpu target aarch64 and then copy the binary over to mendel. Using docker and all of the libraries needed will boat the board and for sure run out of ram to build.
I recommend you have something to the same effect as your explanation in your comment above in the README.md. Perhaps a preface of:
This project is designed to be downloaded onto a workstation where the program will be cross-compiled within Docker for installation on the Google Coral Dev Board. This is not intended for direct installation on the Coral Dev Board.
@jlpoolen we have updated build instrucitons for the dev board in the README.md file. Thanks for the feedback!
