             struct hdr_apit *wd = HDR_APIT(p);
                                             ^

Answer 1

The three "missing" definitions are done in apit_packet.h, line 41 .. 43

#define HDR_APIT(p)             ((struct hdr_apit*)hdr_apit::access(p))
#define HDR_APIT_BEACON(p)      ((struct hdr_apit_beacon*)hdr_apit::access(p))
#define HDR_APIT_RSSI(p)        ((struct hdr_apit_rssi*)hdr_apit::access(p))

... So all you have to do is to add a line (66) to cmu-trace.cc :

#include <apit/apit_packet.h>
