A dll is probably your best option, if you can make it work with the C++ 
code(?).  I would have thought you needed a C interface, though.  


dmc is rarely supported by the majority of open-source projects out there, 
so you end up having to fix a lot of makefiles and a lot of code.  It is 
especially difficult getting C++ code working with such projects because 
many of these will use macro definitions to enable/disable certain vendor 
compiler features.  Also you will run into C++ implementation differences 
that make dmc choke.


On several occasions where I've tried to use dmc for the same reason, and 
I've come to the conclusion that dmc support is a whole project in itself. 
 It's a huge waste of time if all you want is to interface with a library. 
 I recommend the ddl route if you can make it work.  Most others have done 
the same.


Incindentally, if you are curious why projects like Derelict and other bindings 
(using dynamic loading) are so oft used in the D community, this is pretty 
much the reason.
