How to import a custom function file in C (gcc)












0















I tried to import a c file with the help of a header. my code goes as follows:



#ifndef MYFUNCTIONS_H
#define MYFUNCTIONS_H
#endif
#include <stdio.h>

int square(int a);
//my header


my custom function file is:



#include "myfunctions.h"

int square(int a)
{
return a*a;
}


and my main function file:



#include <stdio.h>
#include <stdbool.h>
#include "myfunctions.h"

int main()
{
printf("%d", square(5));
}


my gcc is giving me "Unidentified reference to square" even though this works perfectly fine in windows.
