* Under linux:
   - create the object
     g++ -c test.cpp
   - link:
     dmd test.d test.o

* Under windows 32 bit:
  - create the object:
     Use digital mars C/C++ (dmc) to create an OMF object (GCC 
would produce COFF) then
  - link:
     dmd test.d test.obj

Note that in both cases it can be better not to use the same name 
for the cpp object.
With more C++ objects you could create an archive (aka static 
library) but for just one source this is useless.
