How can I use GDB with Makefiles for debugging?

How can I use GDB with Makefiles for debugging my C program?

You can use GDB with Makefiles by adding debugging flags to your Makefile. Include -g in your compiler flags.

What does the -g flag do?

The -g flag tells the compiler to include debugging information in the executable, which GDB uses to provide a better debugging experience.

Can you show me an example of a Makefile with GDB support?

Sure! Here's a simple example:

CC=gcc
CFLAGS=-g -Wall

all: myprogram

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

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

How do I run GDB after compiling with this Makefile?

After compiling, you can run GDB by executing gdb ./myprogram in your terminal.
