 Check out the COM example (dclient.d and dserver.d) in \dmd\samples\d,

 that should be helpful.

If you look at the all.sh file, it gives some hints: # COM client/server example $(DMD) -c dserver -release $(DFLAGS) $(DMD) -c chello $(DFLAGS) $(DMD) dserver.obj chello.obj uuid.lib ole32.lib advapi32.lib kernel32.lib user32.lib dserver.def -L/map $(DMD) dclient $(DFLAGS) ole32.lib uuid.lib It looks like the server example needs uuid.lib, ole32.lib, advapi32.lib kernel32.lib, and user32.lib. The client seems to need ole32.lib and uuid.lib. -- Justin (a/k/a jcc7) http://jcc_7.tripod.com/d/
