midl cenerated dlldata.c does not compile

Question

Hi, i try to build the dlldata.c file generated by midl compiler. At link time e get the error:
dlldata.obj : error LNK2001: Nicht aufgelöstes externes Symbol "SERVER_ProxyFileInfo".

EXTERN_PROXY_FILE( SERVER ) // extern "C" const ProxyFileInfo SERVER_ProxyFileInfo;

The Problem is:
"SERVER_ProxyFileInfo" ist externally defined. But where is it. Is there a lib which i'm not linking against? server.idl

import "unknwn.idl"; //

proxy.def

LIBRARY				Proxy.dll

makefile
