Unix网络编程（卷二）源码编译报错解决

源码下载地点：http://www.kohala.com/start/unpv22e/unpv22e.html

1、按照Readme操作，进入lib目录下make报错：

gcc -g -O2 -D_REENTRANT -Wall -D_POSIX_PTHREAD_SEMANTICS   -c -o daemon_inetd.o daemon_inetd.c

In file included from /usr/include/netinet/in.h:24,

                 from /usr/include/rpc/types.h:90,

                 from /usr/include/rpc/rpc.h:38,

                 from unpipc.h:115,

                 from daemon_inetd.c:1:

/usr/include/stdint.h:49: error: duplicate ‘unsigned’

/usr/include/stdint.h:49: error: two or more data types in declaration specifiers

/usr/include/stdint.h:50: error: duplicate ‘unsigned’

/usr/include/stdint.h:50: error: duplicate ‘short’

/usr/include/stdint.h:52: error: duplicate ‘unsigned’

/usr/include/stdint.h:52: error: two or more data types in declaration specifiers

make: *** [daemon_inetd.o] 错误 1

修改config.h 注释掉一下三行：

//#define uint8_t unsigned char               /* <sys/types.h> */

//#define uint16_t unsigned short             /* <sys/types.h> */

//#define uint32_t unsigned int               /* <sys/types.h> */

2、链接报错：将生成的libunpipc.a链接到我们的c程序时报错。

collect2: ld returned 1 exit status

解决办法：gcc 添加-lrt命令选项（具体查看man mq_open)

3、找不到GetOpt：

/tmp/ccv1UEy3.o: In function `main':

mqcreate1.c:(.text+0x3a): undefined reference to `GetOpt'

collect2: ld returned 1 exit status

直接把程序改了getopt，没关系。
