Building

Prerequisites

• CMake
• Ninja
• Make
• xorriso
• An x86_64-elf-gcc cross compiler if you are building for x86_64.
• WSL2 if you are on windows.

Build Instructions (x86_64)

1. Open a terminal (or WSL if on windows), and clone the GitHub repository with these commands:

git clone https://github.com/oberrow/obos.git
cd obos
git clone https://github.com/limine-bootloader/limine.git --branch=v5.2023-20241006.0-binary --depth=1

You can ignore any warnings.
2. Configure cmake with this command:

cmake --toolchain src/scripts-toolchains/x86_64/toolchain.cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja .

3. Finally, build the kernel with these commands:

make -C limine
ninja -j 0

The iso image will be stored in out/obos.iso
If you have qemu installed, you can run a virtual machine with the os by running scripts/launch-qemu.sh
