digitalmars.D - How to create a DLL

I try to build a DLL with dmd on windows with tango.

with empty functions that worked. When i put only a switch statement
into a method, the linker complains about a missing "__Dmain". Why is that?

Did you include a DllMain?

Also check out the mydll example the comes with dmd.

Please note that the process of actually initializing the runtime for a 
Tango DLL is somewhat different than Phobos.  You basically just call 
rt_init() to initialize and rt_term() to terminate.  I'll see about 
documenting this somewhere.

I don't think DLL's are created with the linker, they are created with 
lib.exe -> http://www.digitalmars.com/ctg/lib.html

No, DLLs (aka Dynamic Link Libraries) are created by the linker. 
Libraries (aka Static Link Libraries) are created by lib.
