I tried creating a D DLL which I use in a D application and followed the steps in the DLL Howto on the homepage. Everything worked out fine so far but when I actually try to use a module thats defined within the dll and import it I get a linker error:

 Error 42: Symbol Undefined _D6thBase6format12__ModuleInfoZ

All the other functions I use from the dll link fine though.
When running the dll through dumpbin from visual studio the requested module is not listed in the exported symbols list of the dll.
What did I do wrong?

Kind Regards
