I am trying to make an Operating System using HelenOS and making big changes to it, but I want to re build the OS whenever I make a change to the code, how do I do that? I looked carefully and thought about using the "ninja" command, ninja command is used for building the OS, but whenever I type it in it says ninja: no work to do. How do I fix that?
Here is the link for building the OS: https://github.com/HelenOS/helenos
