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