Refactoring of makefiles is here. Looks like a bit less of a mess, thankfully. Also now using `ld` and `as` instead of `gcc` for everything. Seems to work OK for now - but may bite on the ass later. We'll see!

###CONFIGURATION
ARCH := i686
CROSS := $(ARCH)-elf-
This underwent some crazy scope creep. Just one more feature... - Changed primary assembler to NASM. Specifically so I could use - - Swapped start.s to intel syntax. I find it prettier. Learned a lot doing it tbh. - Changed the name of the multiboot structures in C.

CC := $(CROSS)gcc
LD := $(CROSS)ld
QEMU := qemu-system-i386
Moved i/o content to kerno.c Added function for integer -> string (library pending) Modified makefile to reflect use of include/ dir
2025-05-29 03:19:50 +00:00
INCLUDES:= include/
First content commit. Added sample code hello world with personal comments for study Also made a makefile that can build and run the thing. Current run method is directly from QEMU - but the makefile will later make an image with a given bootloader.

Temporary "default output" global, makefile changes. Default output variable holds a generic writer, and any output that isn't really sure where to output to can just output there. Set by the system early in boot. Also made some changes to the makefile to support arguments in the "make run" or "make debug" subset of calls. For now, it's just VGA=1/0 or SERIAL=1/0 to enable/disable VGA/serial. Defaults are VGA=1, SERIAL=0.

Page frame setup done, plus makefile changes. Makefile now has VGA=2 to set the QEMU monitor to STDOUT. Nice for things like memory dumps. Can now parse the memory and create a bitmap of workable regions. Allocation soon(tm)

Makefile is getting a little messy, i'll rework it later, probably. Anyway, now: make iso -> creates iso with bootloader make run_iso -> runs iso in qemu make run -> runs kernel without bootloader or img creation

Quick addition to the makefile, run_iso will build the ISO image and then run the full image. As opposed to run, which will just run the kernel from QEMU.

Added some framework to create a bootable ISO with grub as the bootloader. Eventually the bootloader will be a submodule of this dir - but for now GRUB works for boot.
