You might have to wait a while for that. AFAIK there are no plans
currently to make phobos available as a shared library yet.

I personally think that phobos *should* be a shared object at some
point, but not everyone agrees with me.

I think that phobos should be a shared object too, but only when it has some sense (by now, every dmd release breaks previous libraries, at least gtkd ones)

I suppose D/Phobos is currently still too volatile to start committing
to shared library version numbers yet. One *could* in theory start doing
it and just end up with very large version numbers, which the system in
theory can handle just fine, although people seem aversive to the
possibility of having /usr/lib/libphobos.so.2.x for all x from 0 to some
very large number.

ldc build already phobos / druntime as shared lib with
/usr/lib/libphobos.so.2.x
/usr/lib/libphobos.so.2
/usr/lib/libphobos.so.2

and same for druntime

this it is good for dmd and gdc but ldc use -soname without -L
gdc: -Xlinker -soname 
ldc: -soname
dmd: -L -soname


with ldc you do not to do calling the linker with $(LINKERFLAG

Well, i am able to build the GtkD shared libs for ldc2 with the current 
make file.

Not sure why ldc has it's own soname flag as only the linker would care 
about it so using -L to pass it on to the linker works just fine.

Do the ldmd and gdmd wrapper scripts handle this?

no but i will add it soon, waiting klickverbot or sokol


Mike Wey could you look if soname is really setted with
objdup -p libgtkd.so.1.5 | grep -i soname

$ make shared-libs DC="ldc2"
[ Lots of text scrolls by ;) ]

$ objdump -p libgtkd.so | grep -i soname
  SONAME               libgtkd.so.1.5

ldc is called like this by the make file:
ld -r "All the object files" -o libgtkd.so.o
ldc2 -shared -oflibgtkd.so -L-soname=libgtkd.so.1.5 -L-ldl -m64 libgtkd.so.o
