Well, one way that should be so would be if, for example, a hypothetical 
maker of UN*X boxes, whose version of UN*X includes libpcap, were to put 
out an online OS update that upgrades its version of libpcap as part of 
a tcpdump/libpcap upgrade to plug some security holes, with the upgrade 
to libpcap being an upgrade from a version without pcap_breakloop() to a 
version with pcap_breakloop(), and if that vendor were to treat header 
files as part of its development tools, and not to update them with that 
online OS update, so that you have a library with pcap_breakloop() and a 
header file that doesn't declare it.

As you built and installed libpcap yourself, that wouldn't be it, so 
we'd have to look elsewhere.  What are the contents of your config.log file?

Are you compiling with the latest version of plugins/ethercat/ecatmb.h? 
   What, for example, are the definitions of SoeHeaderControlUnion and 
PETHERCAT_SOE_HEADER in that header?  They should be

typedef union tSoeHeaderControlUnion
{
   struct
   {
      guint8 OpCode     : 3; /* 0 = unused, 1 = readReq, 2 = readRes, 3 
= writeReq, 4 = writeRes
                             5 = notification (command changed 
notification)*/
      guint8 InComplete : 1; /* more follows*/
      guint8 Error      : 1; /* an error word follows */
      guint8 DriveNo    : 3; /* drive number */

      guint8 DataState  : 1; /* follows or requested */
      guint8 Name       : 1; /* follows or requested */
      guint8 Attribute  : 1; /* follows or requested */
      guint8 Unit       : 1; /* follows or requested */
      guint8 Min        : 1; /* follows or requested */
      guint8 Max        : 1; /* follows or requested */
      guint8 Value      : 1; /* follows or requested */
      guint8 Reserved   : 1;
   } v;
   struct
   {
      guint8 Control;
      guint8 Element;
   } v2;
} SoeHeaderControlUnion;

and

typedef struct TETHERCAT_SOE_HEADER
{
   SoeHeaderControlUnion anSoeHeaderControlUnion;
   SoeHeaderDataUnion anSoeHeaderDataUnion;
   /* typedef union tMailBoxDataUnion
   {
   guint8    Data[]   rest of mailbox data  if (Error==0)
   guint16 ErrorCode                        if (Error==1)
   } MailBoxDataUnion;*/
} ETHERCAT_SOE_HEADER, *PETHERCAT_SOE_HEADER;
