WiFi IoT 源码里是有以下几个示例的，demolink/iothardware/samgr，前两个可以正常编译运行，但第三个即samgr时却遇到了问题。

使用的源码是从这里下载的：https://repo.huaweicloud.com/harmonyos/os/1.0/code-1.0.tar.gz

1. 第一处错误就是关于SAMGR_GetInstance()的。

后搜索发现此问题已经解决了，https://gitee.com/openharmony/applications_sample_wifi_iot/pulls/2。鸿蒙系统在gitee上开源，已经提PR修复了此问题。但在官网上下载的源码压缩包并没有同步更新，于是就按此文档介绍的添加了头文件。

2. 按文档添加头文件后发现还有问题，如下，漏掉了bootstrap_example.c里添加头文件，于是添加了#include "time_adapter.h"。

../../applications/sample/wifi-iot/app/samgr/bootstrap_example.c: In function 'FEATURE_OnInitialize':
../../applications/sample/wifi-iot/app/samgr/bootstrap_example.c:75:96: error: implicit declaration of function 'SAMGR_GetProcessTime'; did you mean 'SAMGR_GetInstance'? [-Werror=implicit-function-declaration]
            osThreadGetId(), g_initIndex++, parent->GetName(parent), feature->GetName(feature), SAMGR_GetProcessTime());
                                                                                                ^~~~~~~~~~~~~~~~~~~~
                                                                                                SAMGR_GetInstance

3. 头文件都添加好后却又出现了另一个问题，如下，fatal error: unity.h: No such file or directory

在vscode里搜索unity.h发现有两处，一处位于cJson内部，另一处在third_pard/unity目录下，还发现了其他地方引用方式，于是在/applications/sample/wifi-iot/app/samgr/BUILD.gn里添加了"//third_party/unity/src"，终于编译成功了。

In file included from ../../applications/sample/wifi-iot/app/samgr/broadcast_example.c:22:0:
../../test/xts/tools/hctest/include/hctest.h:22:10: fatal error: unity.h: No such file or directory
 #include "unity.h"
          ^~~~~~~~~

4. 下面看一下都修改了哪些文件

需求注意的是下面贴出的图片仅是applications/sample/wifi-iot/app目录的修改，在foundation/distributedschedule/services/samgr_lite/samgr/source/BUILD.gn文件也有修改。
