ld：警告：忽略文件

Question

ld: warning: ignoring file file, file was built for unsupported file format ( 0x70 0x6F 0x6A 0x61 0x0A 0x6F 0x64 0x6F 0x64 0x6F 0x6B 0x64 0x6F 0x6B 0x64 0x6F ) which is not the architecture being linked (x86_64): file

这是编译程序后的错误。在我的程序中，我想在一个名为file的文件上打印80个字符。

这是我的计划：

#include <sys/types.h>
#include <sys/uio.h>
#include <unistd.h>
#include <fcntl.h>
#include <stdlib.h>
#include <stdio.h>

void    print_80_char(char *path)
{
    int i;
    int fd;
    char *buf;

    fd = open(path, O_RDWR);
    buf = malloc(sizeof(char) * 80);
    i = 0;
    while (buf[i] <= 79)
    {
        read(fd, buf, 80);
        printf("%c", buf[i]);
        i++;
    }
}

我的主要是：

#include <stdlib.h>

void print_80_char(char *path);

int main()
{
    print_80_char("file");
    return 0;
}
