【HarmonyOS HiSpark IPC试用】开发Hi3518第一个示例程序Say Hello to HarmonyOS

本帖最后由 fannifu 于 2022-3-15 23:05 编辑

开发者需要在Linux服务器上下载并解压一套源代码，获取Hi3518源码（下载链接https://gitee.com/openharmony/docs/blob/master/get-code/%E6%BA%90%E7%A0%81%E8%8E%B7%E5%8F%96.md）。更多源码获取方式，请见源码获取。

下载是用windows10, 放在e盘
  1. cd ~
  2. cd  /mnt/e


解压源码
vscode 安装wsl:ubuntu插件可以打开 wsl:ubuntu文件， 这点用win10非常方便
引用:
#include "los_sample.h"
int main(int argc, char **argv)
    printf("n************************************************n");
    printf("Hi I'm Lojam, Hello OHOS!nr");
    printf("Copyright @sunshine Silicon nr ");
    printf("n************************************************nn");
    LOS_Sample(g_num);        // 鸿蒙系统特有的我也不知道是什么意思， 同一个示例目录里 调用los_samle.c里的LOS_Sample函数
    return 0;
}



los_samle.c内容

  1. #include

int g_num = 81;
void LOS_Sample(int param)
{
    printf("This is a sample: Param = %dn", param);
}



看看这个目录的Makefile内容

    编译
    之前Linux开发uboot、内核、文件系统、应用是分开编译的，一般只编译一次烧录，应用直接make编译出来copy到硬件环境里就可以了
    这里是所有的uboot、内核、文件系统、应用一起编译初次使用还有，后面老全部编译就很麻烦了，编译时间长，希望可以应用直接编译，然后copy到板子里，后面写应用或驱动就方便多了
    1. python build.py ipcamera_hi3518ev300 -b debug



    编译出错了，把编译日志放出来，希望能有大神帮助解决， 我找问题解决了再更新了…………OMG………………
