ArkCompiler Development

Introduction

ArkCompiler is a unified programming platform. Its key components include a compiler, toolchain, and runtime. ArkCompiler supports compilation and running of high-level programming languages on the multi-chip platform and accelerates the running of applications and services on mobile phones, PCs, tablets, TVs, automobiles, and smart wearables.

Environment Setup

Ubuntu 18.04 or later is recommended.

Install dependent tools.

sudo apt-get update && sudo apt-get install python ruby python3-pip git-lfs gcc-multilib g++-multilib zlib1g-dev libc++1 curl nodejs

Install the repo tool.

mkdir ~/bin/
curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > ~/bin/repo
chmod a+x ~/bin/repo
export PATH=~/bin:$PATH
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple requests

Download source code.

repo init -u https://gitee.com/ark-standalone-build/manifest.git -b master
repo sync -c -j8
repo forall -c 'git lfs pull'

Install the compiler and binary tool.
```
./prebuilts_download.sh
```

How to Develop

Create the build products ark_js_vm and ts2panda.
```
python ark.py x64.release
```
- ark_js_vm: executable program for running .abc files.
- ts2panda: tool that converts ArkTS files into ArkCompiler bytecode files.

Use ts2panda to convert a TypeScript file to an .abc file.

prebuilts/build-tools/common/nodejs/node-v12.18.4-linux-x64/bin/node --expose-gc out/x64.release/clang_x64/obj/arkcompiler/ets_frontend/ts2panda/build/src/index.js helloworld.ts --opt-level 0

Code snippet of the TypeScript case file helloworld.ts:

declare function print(arg:any):string;
print("Hello world!");

Run the generated .abc file.
```
out/x64.release/clang_x64/arkcompiler/ets_runtime/ark_js_vm helloworld.abc
```
.abc file: ArkCompiler bytecode file.

The execution output is as follows:
```
Hello world!
```

Running the Test262 Test Suite

python ark.py x64.release test262

Build Options

Select a build mode, for example, mode for building a debug version on an x64 platform.

python ark.py x64.debug
