【HarmonyOS HiSpark IPC试用】开发Hi3518第一个示例程序Say Hello to HarmonyOS
【HarmonyOS HiSpark IPC试用】开发Hi3518第一个示例程序Say Hello to HarmonyOS, https://www.pcbbar.com/data/attachment/forum/202009/12/154809tz1xr3m1v91j82x8.jpg <span]<span]
<span]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。 <span]下载是用windows10, 放在e盘 <span]cd ~ <span]解压源码 <span]
<span]
<span]
<span]vscode 安装wsl:ubuntu插件可以打开 wsl:ubuntu文件， 这点用win10非常方便 <span]#include “los_sample.h“ <span]int main（int argc, char **argv） <span] printf（“\n************************************************\n“）; printf（“Hi I\“m Lojam, Hello OHOS!\n\r“）; printf（“Copyright @sunshine Silicon \n\r “）; printf（“\n************************************************\n\n“）; 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
#include <stdio.h>
int g_num = 81; void LOS_Sample（int param） { printf（“This is a sample: Param = %d\n“, param）; }

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 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………………
