例外与反思(Exception and Reflection)

 主要问题是你建立objs的规则： 
 
%.o: %.c $(DEPS)
    $(CC) -c -o $@ $< $(CFLAGS)
 
 在$（INC）中不使用您的包含路径 
 
 另一个问题是您在错误的文件扩展名上进行匹配。 例如， %.c应为%.cpp 。 
 
 你还有一些额外的冗余垃圾，所以我建议你像这样更新你的makefile来得到这个想法： 
 
CC=gcc

DEPS = hello.h
OBJ = hello.o
INC=-I. -I../lib/StanfordCPPLib

%.o: %.cpp $(DEPS)
    $(CC) $(INC) -c $<

hellomake: $(OBJ)
    g++ -o $@ $^
 
 这在我的小模拟设置中构建良好。 请记住，在hellomake:下使用g ++实际上是必要的hellomake:要正确链接所有内容。 

The main problem is that your rule for building objs:
 
%.o: %.c $(DEPS)
    $(CC) -c -o $@ $< $(CFLAGS)
 
doesn't use your include path in $(INC)
 
Another problem is that you are matching on the wrong file extension. e.g. %.c should be %.cpp.
 
You also have some extra redundant junk in there, so I suggest you update your makefile like this to get the idea:
 
CC=gcc

DEPS = hello.h
OBJ = hello.o
INC=-I. -I../lib/StanfordCPPLib

%.o: %.cpp $(DEPS)
    $(CC) $(INC) -c $<

hellomake: $(OBJ)
    g++ -o $@ $^
 
This builds fine in my little mock setup. Remember that it is actually necessary for you to use g++ under hellomake: for everything to link properly.
