Makefile for multiple C programs

Question

I've got a task to do a makefile of 5 different c programs. Let's call them 1.c, 2.c, 3.c, 4.c, 5.c The code i've got is:

CC = gcc
CFLAGS = -Wall
LDFLAGS =
OBJFILES = 1.o 2.o 3.o 4.o 5.o 
TARGET = 1 2 3 4 5

all: $(TARGET)
$(TARGET): $(OBJFILES)
    $(CC) $(CFLAGS) -o $(TARGET) $(OBJFILES) $(LDFLAGS)
clean:
    rm -f $(OBJFILES) 

And the feedback is that I should do something with static template. How should I approach this problem?

Answer 1

You should let Make use its default rules. Your entire Makefile can be as simple as:

CC = gcc
CFLAGS = -Wall

all: 1 2 3 4 5 

But if you are willing to require the user to type make 1 and make 2, etc., you can just delete the makefile completely. Let the user specify CC and CFLAGS in their environment if needed/desired.

Answer 2

I don't know what you mean by a static template, but your Makefile does not work. Try this change instead:

$(TARGET): $(OBJFILES)
        $(CC) $(CFLAGS) -o $@ [email protected] $(LDFLAGS)

The drawback is that it compiles all five programs even if only one has to be rebuilt.
