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. -- Mike Wey

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. T -- Lottery: tax on the stupid. -- Slashdotter

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.

It compiles to 32-bit but fails for 64-bit, maybe due to compiled libphobos2 (64-bit) without -fPIC argument? Another thing. $ dmd -fPIC -shared foo.d -m32 -offoo.so.0.0.1 generate the incorrect "foo.so.0.0.so" file name. but with: $ dmd -fPIC -shared foo.d -m32 -L-ofoo.so.0.0.1 the correct "foo.so.0.0.1" file name is created.
