Hi,
I have same issue, but it is possible make shared library,
first of all you have to make shared variant of druntime and
phobos library, than it should work ok.
Now I am at work, when I come back home I will post some more
details about this.

Haven't done any dynamic linking with D and I need to. I'm
using dmd 2.058/Linux at work to build and use dynamic

dmd main

dmd -fPIC -shared lib.d -of./lib.so
*** lib.d
extern(C) int fun(string s)

Running make prints:

What steps do I need to take to get off the ground?
Thanks,
