🌠System Template

🔧This is a template that can help you quickly build your own OS using rust.

🦀HanabiOS is built on it.

🙏I hope that everyone can use it to understand and learn the underlying principles of computers and the operation of operating systems without barriers!

📕Prepare For It

1. 🌙Use the following command to install the nightly version of rust,

   😀because we may need to use some features that only this version provides.

rustup install nightly

2. 🔧Then set the toolchain used in this project to nightly version of rust.

   🔭In the future we can enable some experimental features by adding feature flags at the beginning of main.rs,

   😫such as adding #![feature(asm)] to enable experimental introverted compilation.

rustup override add nightly

3. 🔧Configure your target.json,

   📜here we only provide target.json to help you build the system for the x86_64 architecture platform.

   😀If you have other written target.json,

   welcome to submit it to us!

4. 📦Install xbuild and bootimage,

   🏭they can help you quickly build an operating system image.

rustup component add rust-src
rustup component add llvm-tools-preview
cargo install cargo-xbuild
cargo install bootimage

5. ✍From now on you can directly start writing the code of the operating system!

   The entry point of this operating system is the _start function in main.rs!

🏃‍Build And Run

cargo bootimage --target target.json
qemu-system-x86_64 -drive format=raw,file=./target/target/debug/bootimage-os_template.bin

🛑Precautions

1. 😫You will not be able to use anything in std::,

   🔨you need to construct your own api and call it.

2. 📜The target.json given here can only help you build an operating system for the x86_64 platform,

   ✍please write your own for other platforms!

   🤝If you have target.json for other platforms,

   🤣please submit it to us!

   ❤Thank you!
