Compilation sous DEV C++

Bonjour,

Je me permet de vous demander un grand HELP, je viens de trouver un script sur internet pour scanner les ports que je voudrais compiler et utiliser durant un stage.
Mais lorsque je lance la compilation sous Dev C++.

Merci de votre aide

Voici le script que je veux compiler :

/*
Port scanner code in c

• /

#include<stdio.h>
#include<sys/socket.h>
#include<errno.h>
#include<netdb.h>
#include<string.h>
#include<stdlib.h>

int main(int argc , char **argv)
{
struct hostent *host;
int err, i , sock ,start , end;
char hostname[100];
struct sockaddr_in sa;

//Get the hostname to scan
printf("Enter hostname or IP : ");
gets(hostname);

//Get start port number
printf("\nEnter start port number : ");
scanf("%d" , &start);

//Get end port number
printf("Enter end port number : ");
scanf("%d" , &end);

//Initialise the sockaddr_in structure
strncpy((char*)&sa , "" , sizeof sa);
sa.sin_family = AF_INET;

//direct ip address, use it
if(isdigit(hostname[0]))
{
printf("Doing inet_addr...");
sa.sin_addr.s_addr = inet_addr(hostname);
printf("Done\n");
}
//Resolve hostname to ip address
else if( (host = gethostbyname(hostname)) != 0)
{
printf("Doing gethostbyname...");
strncpy((char*)&sa.sin_addr , (char*)host->h_addr , sizeof sa.sin_addr);
printf("Done\n");
}
else
{
herror(hostname);
exit(2);
}

//Start the port scan loop
printf("Starting the portscan loop : \n");
for( i = start ; i <= end ; i++)
{
//Fill in the port number
sa.sin_port = htons(i);
//Create a socket of type internet
sock = socket(AF_INET , SOCK_STREAM , 0);

//Check whether socket created fine or not
if(sock < 0)
{
perror("\nSocket");
exit(1);
}
//Connect using that socket and sockaddr structure
err = connect(sock , (struct sockaddr*)&sa , sizeof sa);

//not connected
if( err < 0 )
{
//printf("%s %-5d %s\r" , hostname , i, strerror(errno));
fflush(stdout);
}
//connected_ else
{
printf("%-5d open\n", i);
}
close(sock);
}

printf("\r");
fflush(stdout);
return(0);
}
