Subject: DLL erstellen

Hallo,
Ich versuche seit ein paar Tagen mit Dev-C++ eine DLL zuerstellen. Zum üben habe ich volgenden Quellcode erstellt.

MainDll.cpp
-----------

#include "C:\Dev-C++\FastX\MainDll.h"
#include
#include

/* Externs */
DllClass DLLIMPORT global_dllclass1 (1);
DllClass DLLIMPORT global_dllclass2 (2);
int DLLIMPORT global_int_variable = 5;

int DllClass::instances;

DllClass::DllClass (int i) : i_(i) { ++instances; }
DllClass::~DllClass () { --instances; }

void DllClass::virtual_method ()
{
printf("Hello from virtual method :-)\n\n");
}

void DllClass::non_virtual_method ()
{
printf("Hello from non-virtual method ;-)\n\n");
}

float HOCH(float basis, unsigned int exponent) {
float temp=1;
unsigned int i;
for (i=0; i return temp;
}

DllClass DLLIMPORT potenz;

BOOL APIENTRY DllMain (HINSTANCE hInst, DWORD reason,
LPVOID reserved /* Not used. */ );

/* DllMain Results:
TRUE on success, FALSE on failure. */

BOOL APIENTRY
DllMain (
HINSTANCE hInst /* Library instance handle. */ ,
DWORD reason /* Reason this function is being called. */ ,
LPVOID reserved /* Not used. */ )
{

switch (reason)
{
case DLL_PROCESS_ATTACH:
break;

case DLL_PROCESS_DETACH:
break;

case DLL_THREAD_ATTACH:
break;

case DLL_THREAD_DETACH:
break;
}
return TRUE;

Dll.def
-------

LIBARY "Test.dll"
DESCRIPTION 'Test-DLL'
EXETYPE WINDOWS
EXPORTS
HOCH

Beim linken kommt aber die Fehlermeldung:
gcc: c:\dev-c++\fastx\dll.def: linker input file unused since linking not done

Was mache ich falsch?
