You start by downloading the ingredients (in this case, the source code) and mixing them together with some magic spells called “make” commands. Then you let it bake in the oven (or your computer’s processor) for a while until it’s ready to eat (or install).
Once your cake is done baking, you need to package it up so that other people can enjoy it too. This involves wrapping it up in pretty paper and ribbon (or some fancy packaging software) and labeling it with all the important information like what flavors are inside and any special instructions for eating it.
In Debian-speak, this process is called “building” and “packaging,” respectively. And if you’re feeling adventurous, you can even become a packager yourself by learning how to use some of the fancy tools that come with Debian (like dpkg or apt). But be warned: it’s not for everyone!
Here are some examples to help illustrate this process in action. First, let’s say you want to build and package a new kernel source called “mykernel” from scratch. Here’s what you might do:
1. Download the source code using your favorite web browser or wget command (depending on how tech-savvy you are).
2. Extract the tarball into a directory of your choice, like so: `tar -xzf mykernel_sourcecode.tgz`
3. Change into that directory and run some “make” commands to configure and build the kernel source (this can take anywhere from 10 minutes to several hours depending on how powerful your computer is).
4. Once the kernel source has been built, you’ll need to package it up using dpkg or apt. This involves creating a new .deb file that contains all the necessary information about your kernel source (like its version number and any dependencies it might have).
5. Finally, install your newly-packaged kernel source using either dpkg or apt (depending on which one you prefer). You’ve just built and packaged a new kernel source in Debian!
Of course, this is just the tip of the iceberg when it comes to building and packaging kernel sources. There are all sorts of fancy tools and techniques that can help make your life easier (like cross-compiling or using pre-built binary packages). But for now, let’s stick with the basics and focus on mastering this essential skill in Debian land!
