my file contails the LIBS export line as like this

LIBS= -lrscg -lscg $(LIB_VOLMGT) -lparanoia -ldeflt -lschily $(SCSILIB) $(EXTRALIB) $(LIB_SOCKET)

I have chaged it to

LIBS= -lm -lrscg -lscg $(LIB_VOLMGT) -lparanoia -ldeflt -lschily $(SCSILIB) $(EXTRALIB) $(LIB_SOCKET)

but still i canot rectify the problem

Thanks in advance

Thanks & Regards,
