cant include libipq.h header file

I have a C file of the following .When I execute this in Fedora 7 version 2.6.21-1.3194.fc7 and
arch =i686 I get following errors

[root@kwi-11156f06184 Desktop]# cc test.c
test.c:3:20: error: libipq.h: No such file or directory
test.c: In function ‘main’:
test.c:12: error: ‘PF_INET’ undeclared (first use in this function)

Code:

/* c file called test.c*/

#include <linux/netfilter.h>
#include <libipq.h>
#include <stdio.h>

int main()
{
  int retVal = 0;
  char buf[1000];
  struct ipq_handle* userHandle;

  userHandle = ipq_create_handle(0, PF_INET);
  if(userHandle == NULL)
  {
    printf("ipq_create_handle returned error\n");
    return -1;
  }

  retVal = ipq_read(userHandle, buf, 1000, 0);

  return 0;
}

my problem is how shall I include all these header files , so that my program works

any hints and suggestions
prethanks to helper

Well the first thing you should do is stop writing and compiling programs (and presumably browsing the web) as root. Sooner or later, you'll be wondering where your install disks are because you've either trashed the system or someones hacked it.

As for running the compiler, it would be something like
cc -I/path/to/header test.c
The -I parameter specifies a location where header files may be found, in addition to the usual places.

Or it may simply be that you haven't installed that library.

how shall i install that library
shall I use yum or add/remove software in fedora 7

yum can probably do it. I'm old fashioned, so I would just use rpm to install from the CD/DVD.
