unp[unix 网络环境编程]学习 vscode环境搭建

1. vscode 下载安装 Native Debug,f5打开调试配置,或者按照我的文件直接覆盖就行

2. 参考.vscode的两个文件,其中launch不用修改

3. 如果想自己每次重新编译书本的源码,不使用默认的Makefie,则需修改task.json,这里主要就是增加头文件的路径和链接库的路径,这个参数定义在unpv13e/Make.defines

4. 这个参数其实可以随便找个Makefile 打印变量即可,我这里修改打印看了下

   dbg:
    echo${CC} ${CFLAGS} -o $@ daytimetcpcli.o ${LIBS}
