Introduction
In this challenge, you will learn to create a basic Makefile to compile a simple C program. You'll understand how Makefiles help automate the build process and manage multiple source files.
Create a Basic Makefile
In this challenge, you will create a basic Makefile to compile a simple C program. The program consists of two source files: hello.c and utils.c. The hello.c file contains the main function that prints a message to the console. The utils.c file contains a utility function that is called from the main function.
Tasks
- Create a
Makefilethat compiles the program - Add rules to compile both source files
- Add a
cleantarget to remove compiled files
Requirements
- Use the provided source files in
~/project - The Makefile must compile both
hello.candutils.c - Create an executable named
hello - Include a
cleantarget - Use GCC as the compiler
Examples
Run the following commands to compile the program:
cd ~/project
make
gcc -c hello.c
gcc -c utils.c
gcc hello.o utils.o -o hello
Run the compiled program:
./hello
Example program output:
Hello, World!
Utility function called!
After running the program, clean up the compiled files.
Hints
- Remember to use TAB for indentation in the Makefile
- Use
-cflag to compile source files into object files - Test the program after compilation
Summary
This challenge introduced you to basic Makefile creation. You learned how to write a simple Makefile to compile multiple source files, create an executable, and clean up build artifacts. These are fundamental skills for managing C programming projects.
