Makefile Newbie: Inheritance Question

I'm a bit new to makefiles, so pardon me if this question is really foolish.

If I have a single class called Entity, my makefile will be as follows:

Code:

---

CCC = mingw32-g++
BINARIES = Main.o Container.o Entity.o Object.o Room.o

all : $(BINARIES)
        ${CCC} -o game.exe ${BINARIES}

Main.o : Entity.h
        $(CCC) -c Main.cpp

Entity.o : Entity.h Entity.cpp
        $(CCC) -c Entity.cpp

clean :
        del /q /s ${BINARIES}

---

I'm concerned about the

Code:

---

Entity.o : Entity.h Entity.cpp

---

line. If I later make a class called TempEntity, which is a derived class of Entity, how would I need to compile the O file?

Would it be:

Code:

---

TempEntity.o : TempEntity.h TempEntity.cpp

---

or

Code:

---

TempEntity.o : Entity.h Entity.cpp TempEntity.h TempEntity.cpp

---

and why?

Ohhh, wow. That seems so simple now, I can't believe I missed it before. Thanks!
