so i'm creating a "game" in c, where the user make choices and the content showed to him depends on his choice. So i created different files with multiple functions, functions that i included in header files, header files that i finally included in the other files where i'm calling these function. Here is an example with the type function that write caracters one by one. the first file is step0.c, where i use type function, and where the compiler tell me that the function "type" is undefined here is the error message if it can help :
step0.o: In function eventS0': step0.c:(.text+0x10e): undefined reference to type'
step0.o:step0.c:(.text+0x12b): more undefined references to type' follow step0.o: In function eventS0':

here is the type.c file where the function is defined :
type.c :
#include "type.h"
void type(char *input) { // fonction pour simuler lécriture du texte dans le terminal
int size = strlen(input);
struct timespec pause = {0, 100000000};
for (int i = 0; i < size; i++) {
putchar(input[i]);
fflush(stdout);
nanosleep(&pause, NULL); //délai d'écriture en micro seconde
}
}
and here is the type.h file :
type.h :
#define TYPE_H
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <unistd.h>
extern void type(char *input);
i know this is a lot to look out but i wanted to give as much context as possible. Note that other functions as updateStats, printStats ect are not working either and have the same structure, and that i get this error in all my files. finally i want to provide you my makefile, wich might be my problem because its my first ( i searched everywhere for help but didnt find it ) :
makefile :

i tried adding the source .c files to the makefile dependency as chatgpt told me, but didnt work. i tried modifying the organization of my header and source in all way possible so i dont think its the problem.
