cd unpv12e
./configure
make
vim README看怎么安装
cd unpv12e/lib
make会报错unp.h:114: error: redefinition of ‘struct in_pktin
unp.h中，这段代码注释掉，因为在linux系统include文件中已经定义了这个结构，

/* The structure returned by recvfrom_flags() */struct in_pktinfo {  struct in_addr    ipi_addr;    /* dst IPv4 address */  int      ipi_ifindex;                  /* received interface index */};

cd ../libfree
make
inet_ntop.c:61: error: argument ’size’ doesn’t match prototype
/usr/include/arpa/inet.h:153: error: prototype declaration
在mac下为：

apple:libfree apple$ makegcc -I../lib -g -O2 -D_REENTRANT -Wall   -c -o in_cksum.o in_cksum.cgcc -I../lib -g -O2 -D_REENTRANT -Wall   -c -o inet_ntop.o inet_ntop.cinet_ntop.c: In function ‘inet_ntop’:inet_ntop.c:61: error: argument ‘size’ doesn’t match prototype/usr/include/arpa/inet.h:99: error: prototype declarationmake: *** [inet_ntop.o] Error 1apple:libfree apple$

inet_ntop.c第60行 size_t size ->改成 socklen_t size

#cd ../intro
#make
将daytimetcpsrvv6.c:12行的语句extern struct in6_addr ipv6addr_any;
改为struct in6_addr ipv6addr_any;

#./daytimetcpsrv &
#./daytimetcpcli 127.0.0.1
得到输出时间应该就表示安装初步成功了
