Linux多线程服务端编程学习muduo（四）finger服务的实现

例 七步实现finger服务

---

本文以陈硕老师的 Linux多线程服务端编程 为参考书，展示如何通过陈硕老师的源码编写对应的CMakeLists.txt ，然后编译运行。（在进行本部分的实验前，需要先 进行网络库的安装 参考链接 https://blog.csdn.net/YoungSusie/article/details/90021742 以及 库文件和头文件的设置 参考链接 https://blog.csdn.net/YoungSusie/article/details/90035042）
陈硕老师在源代码中，example/twisted/finger 下包含01-07 代码文件 、 一个 CMakeLists.txt 文件 和一个README 文件

其中，CMakeLists.txt文件的内容

很明显，这不是一个完整的cmakelists 文件，因此，先修改CMakeLists.txt的内容

• 建立CMakeLists.txt 文件

• 修改源代码中的include部分

将finger 01-07 代码中的include " " 全部改为 include <>

全部修改完成后，在finger文件夹下打开一个终端

#  mkdir build

#  cd  build

# cmake ..

#  make

• 测试

在/build/bin 目录下打开一个终端，运行finger07

#  ./twisted_finger07

打开另外一个终端，运行命令

# telnet localhost 1079
