![]() ![]() You’re doing a course on Advanced Operating Systems and have no choice but to do this!.You want to debug kernel source code, enable support for a new piece of hardware, or make modifications to its existing configurations.You want to enable experimental features on your kernel that are not enabled by default (or, disable default features that you don’t want).(Each time you implement your own system call or modify kernel source code, you will need to recompile the kernel to implement the changes) You want to write a really cool ‘Hello world’ program.Here are a few specific cases where you’ll need to know how to work with the kernel’s source code: If you plan to work on the internals of the Linux kernel or change its behavior, you’ll need to recompile the kernel on your system. So, here’s a guide to help you through the process of building the kernel from source, and it’s a guide that works! You will not have to worry about messing up your system or wasting your time. It can also get really irritating if you aren’t following the right instructions. My goal is to present a straightforward approach for doing this, which should hopefully help you save a lot of time.Ĭompiling the Linux Kernel from source can seem like a daunting task, even to someone who’s pretty comfortable with computers in general. There are a number of blogs that already tell you how to go about doing this, but some of them are outdated, and some seem unnecessarily complicated. And I decided to document my approach for building the Linux kernel from source and implementing my own system call. I just finished my first assignment for a course on Advanced Operating Systems.
