GCC编译错误来从标准

我写一个小程序，名为“ioprogram.c”，用GNU readline库，在互联网上闯民宅的各种文档阅读。但是，gcc报告了以下错误。我的问题是什么？

#include <readline/readline.h> 
#include <stdio.h> 
int main() 
{ 
    char* c = readline(""); 
    int len = strlen(c); 
    for(int i=0; i<len; i++) 
    {  
     printf("%c", *(c+i)); 
     fflush(stdout);   
    } 
    free(c); 
}

GCC错误：

In file included from /usr/include/readline/readline.h:37, 
       from ioprogram.c:1: 
/usr/include/readline/rltypedefs.h:65: error: expected ‘)’ before ‘*’ token

ioprogram.c: In function ‘main’: 
ioprogram.c:7: error: ‘for’ loop initial declaration used outside C99 mode

先感谢您的任何意见。

代码编译构建我，我看到你的代码没有语法错误，但你得到的错误提示有一个。请提供您使用的gcc版本，以及您如何编译代码。请记住，您需要链接到readline库（“ - lreadline”）。 – gamen 2011-02-11 11:36:30

尝试 gcc ioprogram.c -o ioprogram -lreadline -lncurses
