Building

Requirements to build

• Rust (https://www.rust-lang.org)

Windows

Windows 10 or later

Starting with Windows 10, you can use Ubuntu Bash. You can run it by typing C:\Windows\System32\bash.exe. For more information, please visit https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

You need to install Rust, qemu, mtools on Ubuntu Bash. You can install Rust using the following command.

$ curl https://sh.rustup.rs -sSf | sh
$ sudo apt install qemu
$ sudo apt install mtools

This script will download and install the rustup-init executable for your current platform.

After the installation is complete, you should clone the SnowFlake repository.

$ git clone https://github.com/SnowFlake/SnowFlake.git

To build SnowFlake as an x86_64 target, x86_64-elf cross-compilation is required. If you do not have the x86_64-elf compiler, and your system is x86_64, you can use the 'x86_64-linux_env.sh' script. And you should add rustup component.

$ cd SnowFlake
$ sh x86_64-linux_env.sh
$ cd kernel
$ rustup component add rust-src
$ cd ./../
$ make run

Windows 8.1 or lower

Will be added later

Mac
