GCC編譯錯誤來從標準

我寫一個小程序，名爲「ioprogram.c」，用GNU readline庫，在互聯網上闖民宅的各種文檔閱讀。但是，gcc報告了以下錯誤。我的問題是什麼？

#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錯誤：

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

先感謝您的任何意見。

代碼編譯構建我，我看到你的代碼沒有語法錯誤，但你得到的錯誤提示有一個。請提供您使用的gcc版本，以及您如何編譯代碼。請記住，您需要鏈接到readline庫（「 - lreadline」）。 – gamen 2011-02-11 11:36:30

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