Hey! I'm following OSDev's tutorials to learn about how operating systems work.

You will need to build a GCC cross compiler, which you can find instructions for here. (I will add internal documentation later probably.)

If you are on ARM, as one of my machines is, you may need to change the -d option on grub-mkrescue in iso.sh to your grub/i386-pc location is, which you may need to manually depackage the grub-pc-bin package for. If you are on x86, you can just remove the option entirely.

To clean the source tree:

./clean.sh

To install all of the system headers into the system root without using the compiler:

./header.sh

To build the operating system:

./build.sh

...or build a bootable cdrom image of the os (without needing to run ./build.sh separately):

./iso.sh

You can then use whatever to run the iso, such as qemu:

qemu-system-i386 -cdrom myos.iso

I want to learn how the bootloader works, as well as memory management and scheduling.

Note: Older commits in this repository may contain bootable ISOs that include GNU GRUB, which is licensed under the GPLv3. The source code for GRUB can be found at git://git.savannah.gnu.org/grub.git.
