在make APUE第二版时出现了这个错误

[panchenji]

错误：
badexit2.c: 在函数‘printfoo’中:
badexit2.c:11: 警告： 格式字符串不是一个字面字符串而且没有待格式化的实参
make[2]:正在离开目录 `/home/panchenji/apue.2e/threads'

badexit2.c代码：
#include "apue.h"
#include <pthread.h>

struct foo {
int a, b, c, d;
};

void

printf(" foo.a = %d\n", fp->a);
printf(" foo.b = %d\n", fp->b);
printf(" foo.c = %d\n", fp->c);
printf(" foo.d = %d\n", fp->d);
}

void *

菜鸟请高人指点

printf(s);

改成

printf("%s", s);

BigSnake.NET,

前面那个好了，但是怎么好像还是没有MAKE成功，请问怎么查看错误阿，终端里显示的好像没有什么错误，只有警告
