Well, all three compilers (DMD, GDC, LDC) can create shared libraries at 
this point. But DMD doesn't actually ship libphobos2 (druntime+phobos) 
as a shared library yet, so this is not going to work out so well. If, 
however, you don't use stock libphobos2, you can pass -shared -fPIC to 
create a shared library.

GDC and LDC, as far as I know, can both create shared libraries. GDC 
does it with the standard options you'd pass to GCC. LDC's command line 
is very similar to DMD's if memory serves.

But (another one!): druntime is not yet ready to handle shared libraries 
properly. This means that exceptions thrown across library boundaries, 
TLS, etc are not likely to work properly.

So, in short: If you're using stock libphobos2, don't bother. If you're 
not using stock libphobos2, you can probably trivially create shared 
libraries.
