kawaii MQTT部署踩坑记录

最近在尝试复现韦东山的MQTT智能家居的项目，在ubantu部署kawaii mqtt时出现了点问题。首先就是直接从jiejieTop那里git下载下来的mqttclient在buid时会出现报错：

Scanning dependencies of target mc-mqttclient_static

怀疑可能是因为宏定义冲突或者编译器标志差异？？？具体原因我也不清楚，即使我运行了sudo apt-get update之后，还是会出现同样的报错，大佬如果有知道的话，请在评论区指导一下小弟。
尝试了一些方法无法解决之后，还是决定使用老师学习资料压缩包doc_and_source_for_projects中的mqtt文件，这个经过测试之后可以成功编译，但是在测试的时候又遇到了问题。

book@100ask:~/Documents/mqttclient/mqttclient$ ./build/bin/emqx

welcome to mqttclient test...

[I] >> /home/book/Documents/mqttclient/mqttclient/mqttclient/mqttclient.c:1468 mqtt_list_subscribe_topic()... there are no subscribed topics...

提示没有已订阅的主题，但是test文件里明明订阅了topic1\2\3，这是因为没有成功连接上test中mqtt_set_host(client, “xxxx”);函数里作者提供的ip，所以并没有成功订阅。建议大家可以按照韦老师的方法，使用.\mosquitto.exe在自己的电脑创建一个broker，记得更改.\mosquitto.conf开放端口，因为他是默认只监听了本地回环地址的。最后成功在ubantu上运行了kawaii mqtt，开心ing！
