I Need Some Help. To Recompile this project after some modifications. about toaruos

It sounds like you made an attempt to build the toolchain locally - the Docker builds assume you are coming from an empty repo, so when your local directory is mapped in, the script that “installs” the Docker image’s toolchain fails.

For the second question, there is a different Docker image with an aarch64 toolchain - you can check the Github Actions configuration to see how that is used. The RPi builds aren’t very useful, though, as I have not made much progress on the USB stack - they can boot to a desktop you can’t interact with, and with some changes you can get a serial console over the miniuart, but they’re not generally useful.

sudo docker run

You should not run docker with sudo. You should add your user to the appropriate group to run docker as yourself. If you run docker as root, the permissions on files produced within the container may cause issues.

Did you make an attempt to build that failed? The last step in the build-in-docker.sh removes the util/local symlink. You can try removing it manually before proceeding - the scripts were not intended for active development.
