网络编程只编译头文件也不通过

[死亡阴影]

C代码如下

代码： 全选

#include <sys/types.h>
#include <netinet/in.h>
#include <netdb.h>
#include <sys/socket.h>
#include <unistd.h>
#include <string.h>
#include <arpa/inet.h>
#include <errno.h>
int mian(void)
{}

错误

请问如何解决我已安装了libc6-dev

问题已解决
原来我在 /usr/local/include 那也有一些头文件 他是优先调用了local里面的源
提示Permission denied
把local的inlcude的代码mv 到新建的save文件夹就好了
这问题真晕
