The problem is that the original program was compiled using v5.0 MQ client but now we are using MQ client v5.3. Had modified the "make file" options as follows but still i could see the errors.
#CLIENT_V5_LIBS = -limqb23ss -limqc23ss -lmqic -lmqmcs -lnsl -ldl
CLIENT_V5.3_LIBS = -limqb23as -limqc23as -lmqic -lmqmcs -lmqmzse -lsocket -lnsl -ldl
