Re: how to make "gmake" recompile the files based on their dependencies' modified time

[Gautam Shejwalkar]

Hi

I think the way in which you are referring the dependencies it's not right. You can try this and check

******************************************
PROGRAM = Astar
DEPENDENCIES = Maze.o Maze.h

all: $(PROGRAM)

%.o : %.cc %.h
    g++ -c $<
$(PROGRAM): $(DEPENDENCIES)
    g++ Maze.o Astar.cc -o $(PROGRAM)
clean:
    rm *.o $(PROGRAM)
********************************************

Hello guys,

I have create a simple makefile as below.

But Whenever i execute make command, it doesn't check if any of the files
have modified time greater that the object file's creation time and just
recompiles the all target.
I have to do make clean everytime I want the Maze.cc to recompile

******************************************
PROGRAM = Astar
DEPENDENCIES = Maze.o Maze.h

all: $(DEPENDENCIES) $(PROGRAM).cc
       g++ Maze.o Astar.cc -o $(PROGRAM)

%.o : %.cc %.h
       g++ -c $<

clean:
       rm *.o $(PROGRAM)
********************************************

Can anyone tell me where am I making a mistake?

regards,
parth
