Question

嗨，伙计们，

我用gnu readline库编写了一个名为“ioprogram.c”的小程序，在Internet上引用了各种文档。但是，gcc报告以下错误。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

提前感谢任何评论。

Answer 1

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

gcc编译错误，gnu readline（）从stdin读取
