最近 sogou开源的workflow项目在github上得到了很大的关注，抱着学习的心态研究一下。https://github.com/sogou/workflow

一、编译安装

git clone --recursive https://github.com/sogou/workflow.git
cd workflow
./configure #在workflow目录下创建build文件夹，整个是用cmake来编译的。
cd build
make #编译成功在workflow目录下生成两个文件夹_include _lib

编译还是非常方便的，只需要依赖OpenSSL>=1.1

二、搭建一个简单的服务端程序

测试通过，简单易使用。
