Quick Start

We provide a cli tool to simplify some action. For example: init, build and so on.

We will now begin to introduce this capability step by step.

Requirement

Before all, we need to install Rust and HarmonyOS NDK.

Rust

For rust, we can use official guide to install it.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

🌈

For more detail about rust, you can visit link

And then we need to install some toolchain and component, which will help use to build prebuild binary for HarmonyOS.

1. nightly toolchain

   OpenHarmony is tier3 target for rust, so we must use custom toolchain or use source-code to build it. Just run this command and set toolchain to nightly

   rustup default nightly

2. rust-std

   Then we need to install source code. Just run this command

   rustup component add rust-src

HarmonyOS NDK

TIP

For the latest SDK Version, You need DevEco Studio NEXT Developer Beta1 (5.0.3.100) or later.

You just need to download the latest DevEco-Studio and download the latest SDK. You can download it with official website

Install

Now, you can install cli tool with cargo.

cargo install ohrs

Simple Project

Using ohrs to init project

ohrs init hello

And using ohrs to build project
