Libft is the first project of the 42 curriculum — the goal is to recreate essential functions from the C standard library and build a personal foundation library to be reused in future projects.
This project involves re-implementing various standard library functions (<ctype.h>, <string.h>, <stdlib.h>, <unistd.h>, etc.) and a few additional helper functions.
Using Makefile, you can compile this library.
To compile the library:
makeThis will generate a libft.a static library file.
You can then link it with any project like this:
gcc main.c -L. -lft -I. -o app| Command | Description |
|---|---|
make |
Compiles the base library |
make bonus |
Compiles the additional linked list functions |
make clean |
Removes object files |
make fclean |
Removes object files and libft.a |
make re |
Rebuilds everything from scratch |
