Hi, I'm new to linux C programming and am in need of the libpcap
library. I can't seem to get the thing to compile though. Maybe you
could help.
Here's the source:
#include <pcap.h>
#include <stdio.h>
static pcap_t *ndp;
int main()
{
char device[] = "/dev/eth0";
char nerror[PCAP_ERRBUF_SIZE];
#ifdef lib_pcap_h
printf( "%d", PCAP_ERRBUF_SIZE );
#endif
//if(
ndp = pcap_open_live( device, 1000, 1, 1000, nerror );
// == NULL ) {
// puts( nerror );
//}
return 0;
}
As you can see, it's nothing spectacular, I was just getting started.
Here's the error I get:
$ gcc -I/usr/include/pcap -lpcap -o porcupine porcupine.c
/tmp/ccUbVZOg.o: In function `main':
/tmp/ccUbVZOg.o(.text+0x51): undefined reference to `pcap_open_live'
collect2: ld returned 1 exit status
$
If you have any ideas for me, I'd really appreiciate it. Thanks in
advance.
Jesse
