惯例先放hello world
本项目地址: https://gitee.com/hiharmonica/lua
下载能在鸿蒙上跑的二进制文件
准备环境
1. 安装 docker
2. 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

static_library里的source参照lua/makefile
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
文件内容如下
- set -e
- rm -rf ./out ./bin
- docker run --rm -ti \
- -e HARDWARE=ipcamera_hi3516dv300 \
- -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
