[Done]plz help me with a simple gcc problem

[ljimmyd]

i began to learn c program language last night. but when i tried this morning,a problem happened.

i wrote :

#include <stdio.h>
main()
{
printf("hello, world\n");
}

then i saved as "helloworld.c". and in terminal "cc helloworld.c"

but it appeared :

helloworld.c:1:19: error: stdio.h: No such file or directory
helloworld.c: In function ‘main’:
helloworld.c:4: warning: incompatible implicit declaration of built-in function ‘printf’


what is the problem?

要安装bulidessential，在新立得里就有。不然头文件无法使用。
