+下方将通过修改源码的方式展示如何编写简单程序,输出“Hello world”。请在下载的源码目录中进行下述操作。
1. 确定目录结构。
开发者编写业务时,务必先在./applications/sample/wifi-iot/app路径下新建一个目录(或一套目录结构),用于存放业务源码文件。
-
- 例如:在app下新增业务my\_first\_app,其中hello\_world.c为业务代码,BUILD.gn为编译脚本,具体规划目录结构如下:

2. 编写业务代码。
新建./applications/sample/wifi-iot/app/my\_first\_app下的hello\_world.c文件,在hello\_world.c中新建业务入口函数HelloWorld,并实现业务逻辑。并在代码最下方,使用OpenHarmony启动恢复模块接口SYS\_RUN\(\)启动业务。(SYS\_RUN定义在ohos\_init.h文件中)

- 配置./applications/sample/wifi-iot/app/BUILD.gn文件,在features字段中增加索引,使目标模块参与编译。features字段指定业务模块的路径和目标,以my\_first\_app举例,features字段配置如下。
