I have found myself copying and pasting certain functions into all of the programs I've written and decided I should maybe put them in their own source files. My programs are in a separate folder from the digital mars compiler. If the function source files are in the same folder as the main program, I have no problem compiling. But I really think that the source files with commonly used functions should be in one central location (ie, the digital mars folder). How can I compile the programs with the other source files in a different location? I tried to figure out how to write a "myfunctions.h" but that didn't get anywhere, either.

A quick example.

First a header file, called mine.h, stored in folder1:

#ifndef MINE_H_INC
#define MINE_H_INC

void Func(int i);
extern int y;

#endif

Then the source for the .h, to be put into mine.c in folder1:

#include "mine.h"
#include <stdio.h>

int y;

void Func(int i)
{
   printf("Old: %d, new %d\n", y, i);
   y = i;
}

Then an application that uses the header file and its function,
to be put into app1.c, in some other folder:

#include "mine.h"
#include <stdio.h>

int main()
{
   y = 12;
   Func(34);
   printf("Y: %d\n", y);
   return 0;
}

Now, assuming that you compile from the commandline:
dmc app1.c ..\folder1\mine.c -I..\folder1

You have to adjust the path to mine.c and mine.h

I don't think you should put your own code into the compilers
folder, but that up to you.

Thanks for the quick and clear reply...it's working fine, now. I'll take your advice on not putting my functions in the compiler file.
