configure: creating ./config.status

config.status: creating Makefile

config.status: creating Make.defines

config.status: creating config.h

编译库：

编译所有例程都需要用到的基础库

$ cd lib

$ make

得到静态库文件：libudp.a

查看符号表（主要是想看一下这个库的各个源文件调用了哪些Linux系统调用）

$ nm -g libunp.a

从中可以发现以下几个文件比较重要，主要是对常用的API进行了一层包装。

wrapsock.o: 对套接字socket的包装

bind

connect

err_quit

err_sys

getenv

getpeername

getsockname

getsockopt

inet6_rth_add

inet6_rth_getaddr

inet6_rth_init

inet6_rth_reverse

inet6_rth_segments

inet6_rth_space

listen

poll

recv

recvfrom

recvmsg

select

send

sendmsg

sendto

setsockopt

shutdown

sockatmark

socket

socketpair

strtol

wrapstdio.o: 对标准IO库中文件相关函数的包装

fclose

fdopen

ferror

fgets

fopen

fputs

wrappthread.o: 对线程库pthread的包装

pthread_cond_broadcast

pthread_cond_signal

pthread_cond_timedwait

pthread_cond_wait

pthread_create

pthread_detach

pthread_join

pthread_key_create

pthread_kill

pthread_mutex_init

pthread_mutex_lock

pthread_mutex_unlock

pthread_mutexattr_init

pthread_mutexattr_setpshared

pthread_once

pthread_setspecific

wrapunix.o: 对其他常用Linux/Unix系统调用的包装

__strdup

calloc

dup2

err_quit

err_sys

fcntl

fork

gettimeofday

ioctl

malloc

mkstemp

mmap

open

pipe

read

sigaddset

sigdelset

sigemptyset

sigfillset

sigismember

sigpending

sigprocmask

sysconf

sysctl

unlink

wait

waitpid

write

问题：为什么要对这些API接口进行包装，是否多此一举？

继续编译基本库

$ cd ../libfree/

$ make

gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o in_cksum.o in_cksum.c

gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o inet_ntop.o inet_ntop.c

inet_ntop.c: In function ‘inet_ntop’:

inet_ntop.c:61: error: argument ‘size’ doesn’t match prototype

/usr/include/arpa/inet.h:65: error: prototype declaration

make: *** [inet_ntop.o] Error 1

出现错误！

Fix:

inet_ntop.c第61行 size_t size ->改成 socklen_t size）

再次编译

$ make

gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o inet_ntop.o inet_ntop.c

gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o inet_pton.o inet_pton.c

ar rv ../libunp.a in_cksum.o inet_ntop.o inet_pton.o

a - in_cksum.o

a - inet_ntop.o

a - inet_pton.o

ranlib ../libunp.a

貌似这次编译的内容并到了libunp.a中，没有生成新的库文件。

$ cd ../libgai

$ make

ar rv ../libunp.a

ranlib ../libunp.a

拷贝生成的库文件到系统库目录

$ cd ..

$ sudo cp libunp.a /usr/lib

$ sudo cp libunp.a /usr/lib32

以后编译代码的时候加上-lunp链接我们的库。

修改unp.h并将其和config.h拷贝到/usr/include中

编译并测试一个基本的客户端例程

$ cd intro/

$ make daytimetcpcli

gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o daytimetcpcli.o daytimetcpcli.c

gcc -I../lib -g -O2 -D_REENTRANT -Wall -o daytimetcpcli daytimetcpcli.o ../libunp.a -lpthread

编译成功后，在当前目录会生成可执行镜像daytimetcpcli

运行daytimetcpcli

$ ./daytimetcpcli

usage: a.out <IPaddress>

$ ./daytimetcpcli 127.0.0.1

connect error: Connection refused

Fix:

开启daytime服务

$ make daytimetcpsrv

gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o daytimetcpsrv.o daytimetcpsrv.c

gcc -I../lib -g -O2 -D_REENTRANT -Wall -o daytimetcpsrv daytimetcpsrv.o ../libunp.a -lpthread

sudo ./daytimetcpsrv &

再次运行daytimetcpcli

$ ./daytimetcpcli 127.0.0.1
