一个有关头文件sched.h的问题

blps

我在编写与内核有关的程序时,只要嵌入头文件sched.h,编译时就会出现一大堆错误,下面是一个最简单的例子:
#include <linux/kernel.h>;
#include <unistd.h>;
#include <stdio.h>;
#include <linux/sched.h>;
int main(){
printf("\n";
}
redhat 8.0,在root下运行:
gcc -D__KERNEL__ -I/usr/src/linux-2.4.18-14/include test.c -o test
出现大量错误,都与系统在sched.h文件中嵌入的头文件,timer.h,time.h等有关,具体错误如下:

请问该如何解决?

老兄，你这个80%都是程序的语法错误！看看c语言的书吧！

不好意思,可能是贴子发得太长了,让人不耐烦看,这样吧,我把问题说得再简单,编译程序出现的一大段错误中,没有一点是main()程序中的语法错误,这些错误都与sched.h有关,如果把sched.h文件去掉,这完全是一个正确的程序.
     因此,可能是嵌入sched.h文件需要做什么工作,请有linux内核编程经验的高手指教,谢谢!
