移植lua到鸿蒙 - 首个移植成功的编程语言
惯例先放hello world
hello world
本项目地址: https://gitee.com/ystyle/lua
下载二进制文件
准备环境
安装 docker
docker pull ystyle/open-harmony
ps: 本文使用与鸿蒙系统一同编译的方法。 如果自己有本地环境，可以把lua项目放鸿蒙代码目录里(或者使用软接连)
下载lua官方代码

mkdir -p ~/code/ohos/
cd ~/code/ohos/
git clone https://github.com/lua/lua.git
编写BUILD.gn文件
因为要与系统一起编译， 为了方便，直接用替换掉示例的方法，这样就只需要写一个BUILD.gn就好了

编译脚本
创建编译脚本build-ohos.sh文件

cd ~/code/ohos/lua
touch build-ohos.sh
chmod +x build-ohos.sh

set -e

docker run --rm -ti \

-v ${PWD}/out:/OpenHarmony/out \
-v ${PWD}:/OpenHarmony/applications/sample/camera/app \
ystyle/open-harmony
mkdir -p ./bin
cp ./out/ipcamera_hi3516dv300/bin/camera_app ./bin/lua
tar -zcf lua-5.4.2-ohos.tar.gz ./bin
echo 'build success!'
与鸿蒙一起编译，这里使用我之前的docker镜像

cd ~/code/ohos/lua
./build-ohos.sh
# 看到 ohos ipcamera_hi3516dv300 build success! build success! 就编译成功了。
编译后软件在鸿蒙的 ./out/ipcamera_hi3516dv300/bin/camera_app
脚本会把lua单独打包出来
单独的lua可执行文件在bin目录
