从网上下载乐unix网络编程这本书的源代码，然后按readme配置：
./configure # try to figure out all implementation differences
cd lib # build the basic library that all programs need
make # use "gmake" everywhere on BSD/OS systems
cd ../libfree # continue building the basic library
make
//* 1*// cd ../libroute # only if your system supports 4.4BSD style routing sockets
make # only if your system supports 4.4BSD style routing sockets
cd ../libxti # only if your system supports XTI
make # only if your system supports XTI
cd ../intro # build and test a basic client program
make daytimetcpcli
./daytimetcpcli 127.0.0.1
从//* 1 *//开始就配置不了，只到cd ../libfree make这里，另外我运行daytimetcpcli的时候提示找不到unp.h，将其复制到相应文件夹，运行如下：
In file included from daytimetcpcli.h:1:
unp.h:122: error: redefinition of ‘struct in_pktinfo’
请问我要如何解决问题呢？

不好意思，刚才没看清楚，当成没找到这个结构体了
redefinition of ‘struct in_pktinfo’
这里报的是重定义
参考这个主题吧：
