Question

我正在使用Linux Mint 13，我正在研究“Unix网络编程：进程间通信”一书。我下载了本书的源代码 - http://www.kohala.com/start/unpv22e/unpv22e.html - 并按照说明进行操作。

首先，我在基目录

中运行./configure

然后，我进入lib目录并运行make。这会产生以下错误 -

gcc -c  "/home/linux/Code/c/unix_network_programming/main.c" -g  -o ./Debug/main.o "-I." "-I." 
In file included from /usr/lib/gcc/i686-linux-gnu/4.6/include/stdint.h:3:0,
                 from /usr/include/netinet/in.h:24,
                 from /usr/include/rpc/types.h:91,
                 from /usr/include/rpc/rpc.h:38,
                 from /home/linux/Code/c/unix_network_programming/unpipc.h:115,
                 from /home/linux/Code/c/unix_network_programming/main.c:2:
/usr/include/stdint.h:49:24: error: duplicate ‘unsigned’
/usr/include/stdint.h:49:24: error: two or more data types in declaration specifiers
/usr/include/stdint.h:50:28: error: duplicate ‘unsigned’
/usr/include/stdint.h:50:28: error: duplicate ‘short’
/usr/include/stdint.h:52:23: error: duplicate ‘unsigned’
/usr/include/stdint.h:52:23: error: two or more data types in declaration specifiers

这是给出错误的文件 -

#ifndef _GCC_WRAP_STDINT_H
#if __STDC_HOSTED__
# include_next <stdint.h>
#else
# include "stdint-gcc.h"
#endif
#define _GCC_WRAP_STDINT_H
#endif

有关如何修复此错误的任何想法，因为我的C经验非常少？

应用以下，温和讨厌的补丁：

然后运行autoconf（使用autoconf2.13而不是更新版本），删除config.cache，然后重试。

Answer 2

只需在 config.h 中注释掉这些行（先执行./configure）：

#define uint8_t unsigned char         /* <sys/types.h> */
#define uint16_t unsigned short       /* <sys/types.h> */
#define uint32_t unsigned int         /* <sys/types.h> */

它对我有用:)。
