pcap error

Hi,

I'm trying to execute the following code

#include <stdio.h>
#include <pcap.h>

int main(int argc, char *argv[])
{
char *dev, errbuf[PCAP_ERRBUF_SIZE];

dev = pcap_lookupdev(errbuf);
if (dev == NULL) {
fprintf(stderr, "Couldn't find default device: %s\n", errbuf);
return(2);
}
printf("Device: %s\n", dev);
return(0);
}

but it is giving me the following error however I've install libpcap

/root/Projects/test/src/main.c:11: undefined reference to 'pcap_lookupdev'

I can't understand the problem.

regards,
Imran

thanks

Did you reference the pcap library on the compile line?

Code:

 cc pcaptest.c -lpcap
