Problem with object file

[ilikesuresh]

Hi all
I wriiten the following problem to handle sockets
but when I try to compile the program It displays,

$ cc -o socket_less socket_less.c
Undefined first referenced
symbol in file
bind socket_less.o
socket socket_less.o
recvfrom socket_less.o
inet_addr socket_less.o
inet_ntoa socket_less.o
ld: fatal: Symbol referencing errors. No output written to socket_less


Program

#include<stdio.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<netinet/in.h>
#include<arpa/inet.h>
#include<string.h>
#include<unistd.h>
#include<stdlib.h>
#define MAX_MSGLEN 100
int main()
{
 int sock,err;
 char msbuff[MAX_MSGLEN+1];
 struct sockaddr_in saddr,fromaddr;
 int fromaddr_len = sizeof(fromaddr);
 sock = socket(AF_INET,SOCK_DGRAM,IPPROTO_UDP);
 if(sock < 0)
 {
  perror("In socket()");
  exit(1);
 }
saddr.sin_family = AF_INET;
saddr.sin_addr.s_addr = inet_addr("127.0.0.1");
saddr.sin_port = htons(61321);
memset(&saddr.sin_zero,0,sizeof(saddr.sin_zero));
err = bind(sock,(struct sockaddr *)&saddr,sizeof(saddr));
if(err)
{
 perror("In Bind");
 exit(1);
}
err = recvfrom(sock,msbuff,MAX_MSGLEN-1,0,(struct sockaddr *)&fromaddr,&fromaddr_len);
if(err)
{
 perror("In Bind");
 exit(1);
}
msbuff[err]='\0';
close(sock);
printf("Message\n\t@bytes:%d\n\t@payload:%s\n",err,msbuff);
printf("Sender \n\t@arrress:%s\n\t@port:%d\n",inet_ntoa(fromaddr.sin_addr),ntohs(fromaddr.sin_port));
return 0;
}
 

Please make it clear me...

You should've asked your question in the corresponding Forum section, not in the
Articles section; I'll move your question there for you.

kind regards,

I have copied this thread to the C forum as well, with the hopes that the folks there may have some insight into the issue you are having.
