C++ Packet Sniffing using WinPCap

[MightyHaku]

Well, I recently started programming and want to look at some network programming - been trying to get WinPCap set up for the past hour but to no avail.

My code is only this so far:

#include <iostream>
#include <pcap.h>
using namespace std;

int main(){
	bool active = true;
	while( active ){
	}
}

EXTREMELY basic, nothing actually going on except a loop and a few includes but pcap.h seems to be spitting out a tonne of errors:

I've done everything they've said I need to do here [url]http://www.winpcap.org/docs/docs_40_2/html/group__wpcapsamps.html[/url]

Does anyone know what could be causing this huge amount of errors?

[ROBO_DONUT]

Try wrapping the include statement like this:

extern "C" {
  #include <pcap.h>
}

[MightyHaku]

Tried like that and like this:

#ifdef __cplusplus
extern "C"
{
#endif
#include <pcap.h>
#ifdef __cplusplus
}
#endif

Both ways still return the same errors.
I guess its the same thing (lol) I just looked it up because I didn't know what you wanted me to do xD

also the comments say

//
// NOTE: remember to include WPCAP and HAVE_REMOTE among your
// preprocessor definitions.
//

do you have those?

also wanna post the headers code that you are using?
