matter 官方代码初体验
入坑
上次edgeX跑起来还算平坦， 没使用源代码编译，docker无疑是一个不错的台阶。 我是熟悉golang的， 所以我是放心的。 但是， matter是c++写的，不是我不熟悉， 而是我知道肯定会被坑。 我太熟悉这些老外了， 他们引用了很多谷歌开源的代码， 这些谷歌代码又引用谷歌工具， 这些工具国内又没人做本地化。
其实我是应该先试用mainflux的， 也是golang实现。 这些更倾向于边缘计算， 而不是智能家居。 我还是觉得智能家居可玩性好一点。以前智能家居不开放， 手机厂商垄断。 有了这个matter的开放协议， 尤其是可以支持个人diy，和usb一样对vid是弱要求。 这个的确赞。
官方代码
看了一些方案实现， 要么是c语言直接引入官方代码。 要么是python等调用官方代码的库。
这思路也不错。毕竟不需要重复造轮子。该入坑的早晚要入。
github https://github.com/project-chip/connectedhomeip
链接看起来很神奇吧。 chip是一个缩写，Connected Home over IP， 链接家庭设备基于IP协议。 其实我觉得， 太专业了。
智能家居over wifi是最常用， 然后用边缘网关扩展到其他协议， 作为一个扩展标准，学习起来就更简单了。
毕竟咱们也搞过多年c++， 不在乎。
build matter https://project-chip.github.io/connectedhomeip-doc/guides/BUILDING.html
上面链接到了构建部分。 噩梦刚刚开始。
程序员喜欢复制粘贴， 更喜欢git clone， 这里提示一下github 近期禁用了匿名代码拉取。
git clone --recurse-submodules git@github.com:project-chip/connectedhomeip.git上面这个代码要把子模块也拉下来。 子模块之多， 让我从来没想到。 网速很快，能达到10Mb/s， 但是， 就这速度， 下载完代码一共19G， 19G的视频，我不怕。 代码我还真怕了。 linux 内核有多大？ 安卓java代码有多大？ 这个小东西要19G真是看不完。
搞嵌入式真是西天取经。 一关又一关。
source scripts/activate.sh要想编译， 不仅仅是根据文档把属于自己专属os的以来安装一下。 还有一个脚本初始化。 因为不同的库，有不同的依赖和构建。 需要持续兼容。 毕竟用文档写， 超越了用户的忍耐能力。大家都知道，写构建代码的人， 大概率能用就行。 人家在国外， 网速快， 并且稳。 我们在wall内， python代码总是报超时。 配了一下https_proxy这个变量， 又配错了。 注意一定要有http:// 否则这个低概率的bug， 官方代码是不可能给你正确的提示的。 他总是提示我python不支持https， 我都重装好几次了。 时间就这么浪费了。 我开始去查python的代码， 一步一步分析才知道又是一个弱智错误导致时间大量浪费的故事。
后面的编译没有遇到什么问题。
切换到quich_start https://project-chip.github.io/connectedhomeip-doc/QUICK_START.html
因为这里有真正的快速入门的验证。 linux和macos是一样的。 用linux入口能看到编译macos上的虚拟样例。
我是arm的macos选用的下面的脚本
$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target darwin-arm64-all-clusters-no-ble-asan build"在 out/darwin-arm64-all-clusters-no-ble-asan/下面编译出来chip-all-clusters-app
我执行一下精选一点日志看看， 但是， 手机是能发现设备的， 但是无响应。 这个后续再看
cat log2.txt| grep -v DMG | head -n 100使用上述命令筛选日志
