Ошибка: не могу вызвать конструктор

Я включил новый модуль в ns2 для оценки передачи видео. Я сделал изменения, которые необходимы для некоторых файлов, таких как agent.h, agent.cc, makefile и так далее.
Во время make застрял с ошибкой.
Ошибка:

myevalvid/myudp.cc: In member function ‘virtual void myUdpAgent::sendmsg(int, AppData*, const char*)’:
myevalvid/myudp.cc:56:123: warning: format ‘%d’ expects argument of type ‘int’, but argument 4 has type ‘long unsigned int’ [-Wformat]
