using dylib with dmd

[frostmind]

Greetings every one,

I desperatly searched net about how to compile a d2
program that uses dylib on mac os, but unfortunately no luck.

What I've been doing:

I have a C library compiled as (taken from http://developer.apple.com/):
gcc -dynamiclib -std=gnu99 Ratings.c -current_version 0.1 -compatibility_version 0.1 -
fvisibility=default -o libRatings.A.g
 --> so I have libRatings.A.dylib that my testapp will use.

I've converted Ratings.h header of the lib to Ratings.d file, all functions enclosed in extern(C);

I created a test program: test_d_client.d

import Ratings;
import std.stdio;

void main() {
	writeln("Starting test");

	char[] value1 = "*".dup;
	addRating(value1.ptr);
	writeln("rating: %s", ratings());
}

And now, when I execute: dmd test_d_client.d I get following output:

Undefined symbols:
  "_addRating", referenced from:
      __Dmain in test_d_client.o
  "_ratings", referenced from:
      __Dmain in test_d_client.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
--- errorlevel 1

What I am doing wrong here?
