I’ve decided to get my hands dirty and try messing around and create a driver for a device. However, the very first problem I run into is that gcc fails to find the following headers:
#include <linux/init.h> #include <asm/irq.h> #include <asm/io.h>
Simply copying and pasting the code from the kernel doc’s “Creating an input driver” (can’t put the link, probably account limiation) immediately gave me a compile error:
fatal error: linux/init.h: No such file or directory
I’ve confirmed that the problem is specifically with finding the headers, as a simple hello world fails to compile and, if I comment or exclude those headers, the compiler works. For the sake of comparison, the headers
<linux/input.h> <linux/module.h> don’t generate a compile error.
sudo pacman -Syu shows that everything is up to date.
linux-api-headers installed and the result of uname -r is
How can I make the compiler find the headers?
