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 -lunpipc

slot.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

         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。
