我的hello.c:
#include <stdio.h>
main()
{
  printf("hello,word\n");
}

编译输入：gcc -o hello hello.c,编译提示如下：

这是什么错误，是不是编程环境没有配置好？

你用的是bsd系统？
加一行在最前面：
#include <sys/types.h>

我用的是ubuntu。一个基于debian的系统。加了后提示还是一样啊。

楼主确信你编辑和编译的是同一个文件吗

haison_first

从输出结果来看和简单的hello.c程序大相径庭！
我建议楼主还是专门建立一个文件夹，然后将
hello.c程序放进去编译。
另外该程序也可以这样写:
#include<stdio.h>
int main()
{
  printf("Hello,world!\n");
  return 0;
}

erniu

成功了，不过编译后执行hello，提示错误：
command not found!
在windows下象我那么写是可以的，为什么在linux下要int main，然后return 0呢？

jin.liu

./hello
Then it will be OK.

标准C就是这么规定的。vc自己支持不标准的写法。

以前在tc下也是这么写的，谭浩强的c语言书也是这么写的。看来要看看标准c了。

那些都是很古老的东东了.
