Hello i try to use pcsc but i get this error can you give me some ideas how to 
solve:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include 
<unistd.h>
#include <string.h>

#include <PCSC/wintypes.h>
#include 
<PCSC/winscard.h>

rv = SCardEstablishContext(SCARD_SCOPE_SYSTEM, NULL, NULL, 
&hContext);

undefined reference to `SCardEstablishContext' 

Thanks
