Compiling to shared library with static dependencies

[Tanel L via Digitalmars-d]

Hello,
I am very new to the D world - but serious in moving over to it 
after I have seen what a cool language it really is.
I am trying to incorporate D into our main product as an 
externally loadable module.

Basically I have a minimal project:

./app.d
./helpers/image.d (mir and dcv libraries imported)
./helpers/utils.d

I am using the latest (statically compiled) ldc2

In my app file(besides the void main) I have a test function 
which I am trying to call from python using ctypes:
extern (C) int doit()

Currently I have gotten as far as getting a loading error in 
python:
library.so: undefined symbol: _d_eh_personality

Googling disclosed that this is satisfied by libdruntime.so, but 
I don't have a shared libdruntime anywhere. I guess I have to 
compile ldc2 in dynamic mode and use the libdruntime.so from 
there?

My build steps until now:

dub.sdl (pseudocode):
   project_description "nudesc"
   dependency "mir"
   dependency "dcv"
   targetPath "lib"
   dflags "-relocation-mode=pic"

dub build --compiler ldc2
cp .dub/obj/*.o lib/
cd lib
ldc2 -of library.so helpers.image.o helpers.utils.o nudesc.o 
-shared -defaultlib=phobos2

strace shows that ldc2 loads "phobos2" from DMD: 
"/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libphobos2.so"

The LDC2 folder only seems to contain libphobos2-ldc.a, no .so's.
Compilation succeeds, but trying to load the so from python:

python  -c "from ctypes import *; CDLL('library.so', 
mode=RTLD_GLOBAL)"
OSError: library.so: undefined symbol: _d_eh_personality

I figured that I don't have druntime.so available because 
druntime is incorporated into LDC2, but mine is statically 
compiled (downloaded precompiled from github i think).

So I tried to compile LDC2 dynamically:
cmake .. -DBUILD_SHARED=ON

But I get a bunch of these errors before the LDC2 build fails:
/home/tanel/thirdparty/ldc-dynamic/build/bin/ldc2: error while 
loading shared libraries: libldc.so: cannot open shared object 
file: No such file or directory
runtime/CMakeFiles/druntime-ldc.dir/build.make:93: recipe for 
target 'runtime/src/core/bitop.o' failed
make[2]: *** [runtime/src/core/bitop.o] Error 127


Basically I am cornered... I really need to be able to compile 
dcv and mir into my dynamic libraries. Probably LDC2 is a must 
because DMD and GDC have given me compilation errors on the 
project even in regular mode. Also LDC2 seems to be the best.

Any ideas what to do or how to proceed?
Thanks a bunch!
