UNIX网络编程 卷2 源代码使用

1. 下载源码，W. Richard Stevens的主页：http://www.kohala.com/start/

wget http://www.kohala.com/start/unpv22e/unpv22e.tar.gz -P /usr/local/src 

2. 解压

tar xvf /usr/local/src/unpv22e.tar.gz -C /root/bin 

3. 编译库文件

cd /root/bin/unpv22e/  

./configure 

编辑生成config.h文件，注释以下几行

vi config.h  

56 // #define uint8_t unsigned char  

57 // #define uint16_t unsigned short  

58 // #define uint32_t unsigned int  

添加MSG_R和MSG_W定义

vi config.h  

66 // add by jcq  

67 typedef unsigned long ulong_t;  

68 #define MSG_R 0400  

69 #define MSG_W 0200 

添加_GNU_SOURCE定义

vi config.h  

#define _GNU_SOURCE 

修改warpunix.c中的MKtemp函数，使用mkstemp函数替换mktemp函数

cd lib  

181 void  

182 Mktemp(char *template)  

183 {  

184 if (mkstemp(template) == NULL || template[0] == 0)  

185 err_quit("mktemp error");  

186 } 

编译生成libunpipc.a

cd lib  

make

 

将生成的libunpipc.a复制到/usr/lib中。

出现上面的错误，使用gcc 加选项-lrt解决。

 

错误：

[root@localhost myunp2]# gcc -lrt -o slot slot.c -lunpipcslot.c: 在函数‘main’中:slot.c:8:22: 错误：‘IPC_PRIVATE’未声明(在此函数内第一次使用)         msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);                      ^slot.c:8:22: 附注：每个未声明的标识符在其出现的函数内只报告一次In file included from slot.c:1:0:unpipc.h:153:21: 错误：‘MSG_R’未声明(在此函数内第一次使用) #define SVMSG_MODE (MSG_R | MSG_W | MSG_R>>3 | MSG_R>>6)                     ^slot.c:8:34: 附注：in expansion of macro ‘SVMSG_MODE’         msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);                                  ^unpipc.h:153:29: 错误：‘MSG_W’未声明(在此函数内第一次使用) #define SVMSG_MODE (MSG_R | MSG_W | MSG_R>>3 | MSG_R>>6)                             ^slot.c:8:34: 附注：in expansion of macro ‘SVMSG_MODE’         msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);                                  ^slot.c:8:45: 错误：‘IPC_CREAT’未声明(在此函数内第一次使用)         msqid=Msgget(IPC_PRIVATE,SVMSG_MODE|IPC_CREAT);                                             ^slot.c:11:22: 错误：‘IPC_RMID’未声明(在此函数内第一次使用)         Msgctl(msqid,IPC_RMID,NULL);

解决方法：

1.unpv22e里面的Make.defines 
修改 
#CFLAGS = -g -O2 -D_REENTRANT -Wall 
CFLAGS = -g -O2 -D_GNU_SOURCE -D__USE_GNU -D_REENTRANT -Wall 

2 将unpv22e中的unpipc.h拷贝到需要编译的代码的目录。

3 将config.h也拷贝到这个目录，由于unpipc.h依赖于这个头文件。
