What are some examples of Makefiles?

Can you show me some examples of Makefiles?

Sure! A Makefile is a file that defines a set of tasks to be executed. Here's a simple example:

all: main.o utils.o
	gcc -o myprogram main.o utils.o

main.o: main.c
	gcc -c main.c

utils.o: utils.c
	gcc -c utils.c

What does each part of this Makefile do?

The all target builds the final executable. The main.o and utils.o targets compile the source files into object files. The gcc commands are the actual compilation commands.

Can I use variables in a Makefile?

Yes, you can! For example:

CC=gcc
CFLAGS=-c

all: main.o utils.o
	$(CC) -o myprogram main.o utils.o

main.o: main.c
	$(CC) $(CFLAGS) main.c

utils.o: utils.c
	$(CC) $(CFLAGS) utils.c

What are some common mistakes to avoid in Makefiles?

Common mistakes include not using tabs for indentation, forgetting to declare dependencies, and not cleaning up object files.
