📦 Build dependencies

To compile GalaxyOS kernel and create basic OS ISO image you need to install following dependencies:

python3 (to run build.py script)
nasm
rust nightly toolchain (with rust-src component)
grub
xorriso
GNU mtools

You can install them with following commands:

Debian-based distributions:

apt install python3 nasm grub-common xorriso mtools curl   # as root
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
rustup toolchain install nightly
rustup component add rust-src

Arch-based distributions:

pacman -S python3 nasm rustup grub xorriso mtools   # as root
rustup toolchain install nightly
rustup component add rust-src

⚙️ Compiling

Clone GalaxyOS repository and change working directory to its location.

To compile use build.py Python (3.6+) script. You can change _*_BINARY variales inside the script to specify non-standard executable locations.

chmod +x build.py
./build.py
# or
python3 build.py

▶️ Running

The kernel binary and basic OS iso are located in build/ directory after compiling.

If you have qemu installed, you can run basic OS in the qemu virtual machine with:

qemu-system-x86_64 -cdrom build/galaxyos.iso

Releases(v0.1.0-alpha.1)

v0.1.0-alpha.1(Nov 12, 2022)
This is first alpha release of GalaxyOS.

It includes basic kernel with 8259 PIC interrupts support.

Multiboot2 kernel parameters are loaded and put on the screen

The kernel successfully allocates pages, remaps itself and initializes memory allocator

You can type something on the keyboard, but deleting characters and moving a cursor is still not supported.

There is uptime displayed on the screen every 10 seconds.

It is known that on some devices Double fault occurs immediately after boot.

Only BIOS boot is supported (VGA Text mode does not exist on UEFI)
