I'm going through Linux Device Drivers 3rd edition to start learn about the kernel and drivers. I know it's outdated, but from my understanding the "high level" of it still applies. Also, I found this repository that has more up-to-date examples from the book. My current issue is that I'm missing linux/init.h which I think I'm supposed to get from the linux-headers package.
From some posts I've seen around the web, installing this should be done with something like
linux-headers-$(uname -r)but I don't see anything in the Arch repo that differs on that the kernel, only linux-headers. My current version (from uname -r) is 6.16.0-arch2-1 but what's out in the Arch repos is 6.16.1.arch1-1. I'm not sure if the versioning difference matters in this scenario. I figured I would try to install it and see if it works/breaks. When doing so though I get;
sudo pacman -S linux-headers

Errors occurred, no packages were upgraded.Which would make sense, since the repo has a different version than my local system. Using pacman -S linux-headers-$(uname -r) gives me a "target not found", as expected. So, my questions are...
- Am I looking in the right place for these headers or is there a better way I should acquire these?
- If the arch repo isn't the best place for me to get them, where should I look?
- If it is the correct place, what package should I be looking for?

it's in /usr/lib/modules/$(uname -r)/build/include/linux/init.h
you got 404 errors because the previous version has been removed from the repos, refresh your databases via upgrading often to prevent that

Ah, just updating my system with a good ol' pacman -Syu worked. Silly me.
