This article will demonstrate how to write a small Limine-compliant x86-64 kernel in (GNU) [[C]], and boot it using the [[Limine]] bootloader.
For this example, we will create these 2 files to create the basic directory tree of our project:
Line 29:
This is the kernel "main".
<
#include <stdint.h>
#include <stddef.h>
Line 155:
}
</syntaxhighlight>
===linker.ld===
Line 246:
GNU make will process it.
<
# Nuke built-in rules and variables.
override MAKEFLAGS += -rR
Line 342:
# Link rules for the final kernel executable.
# The magic printf/dd command is used to force the final ELF file type to ET_DYN.
# GNU binutils, for silly reasons, forces the ELF type to ET_EXEC even for
# relocatable PIEs, if the base load address is non-0.
# See https://sourceware.org/bugzilla/show_bug.cgi?id=31795 for more information.
