I'm trying to set up a project where I can call D functions from C code. Based on the documentation (http://www.digitalmars.com/d/2.0/interfaceToC.html) it looks like I should be able to do the following:

dee.d:
- - - - - - - -
import std.stdio;

extern(C)
{
    void sayHelloFromD()
    {
        writeln("Hello from D.");
    }
}
- - - - - - - -


dee.h
- - - - - - - -
void sayHelloFromD();
- - - - - - - -


cee.c
- - - - - - - -
#include <stdio.h>
#include "dee.h";

int main()
{
    printf("Hello from C.\n");
    sayHelloFromD();
    return 0;
}
- - - - - - - -


To compile:
dmd -c dee.d
gcc dee.o cee.c -arch i386 -o hello

It fails with the following:
Undefined symbols:
  "_D3std5stdio6stdoutS3std5stdio4File", referenced from:
      _D3std5stdio6stdoutS3std5stdio4File$non_lazy_ptr in dee.o
     (maybe you meant: _D3std5stdio6stdoutS3std5stdio4File$non_lazy_ptr)

I would appreciate any help you can give me with this.
