You can use the provided shell script, which (using Ubuntu) reuqires the following packages `build-essential curl bison flex bc rsync kmod cpio lsb-release libssl-dev`.
For increased compatibility, replace the config file provided here with a new configuration based on your system's current configuration.
In this case, you must use a config tool like `make menuconfig` to set the `preemption model` to `Fully Preemptible Kernel (RT)`.
