Question

1）我无法理解第14,15,29-37行。他们的意思是什么？

2）第27行生成的文件“dir.h”也包含在rls_clnt.c和rls_svc.c中。我需要在第5行和第7行指定“dir.h”吗？

  1 CLIENT = dir_client
  2 SERVER = dir_server
  3 
  4 SOURCES_CLNT.c = rls_clnt.c
  5 SOURCES_CLNT.h =
  6 SOURCES_SVC.c = rls_svc.c
  7 SOURCES_SVC.h =
  8 SOURCES.x = dir.x
  9 
 10 TARGETS_SVC.c = dir_svc.c   dir_xdr.c
 11 TARGETS_CLNT.c = dir_clnt.c   dir_xdr.c
 12 TARGETS = dir.h dir_xdr.c dir_clnt.c dir_svc.c
 13 
 14 OBJECTS_CLNT = $(SOURCES_CLNT.c:%.c=%.o) $(TARGETS_CLNT.c:%.c=%.o)
 15 OBJECTS_SVC = $(SOURCES_SVC.c:%.c=%.o) $(TARGETS_SVC.c:%.c=%.o)
 16 # Compiler flags 
 17 
 18 CFLAGS += -g
 19 LDLIBS += -lnsl
 20 RPCGENFLAGS =
 21 
 22 # Targets 
 23 
 24 all : $(CLIENT) $(SERVER)
 25 
 26 $(TARGETS) : $(SOURCES.x)
 27     rpcgen $(RPCGENFLAGS) $(SOURCES.x)
 28 
 29 $(OBJECTS_CLNT) : $(SOURCES_CLNT.c) $(SOURCES_CLNT.h) $(TARGETS_CLNT.c)
 30 
 31 $(OBJECTS_SVC) : $(SOURCES_SVC.c) $(SOURCES_SVC.h) $(TARGETS_SVC.c)
 32 
 33 $(CLIENT) : $(OBJECTS_CLNT)
 34     $(LINK.c) -o $(CLIENT) $(OBJECTS_CLNT) $(LDLIBS) 
 35 
 36 $(SERVER) : $(OBJECTS_SVC)
 37     $(LINK.c) -o $(SERVER) $(OBJECTS_SVC) $(LDLIBS)
 38 
 39  clean:
 40      $(RM) core $(TARGETS) $(OBJECTS_CLNT) $(OBJECTS_SVC) $(CLIENT) $(SERVER)
