Hi I am also new to D and trying to do similar things - i.e. call 
a shared library written in C from D, but also create a shared 
library in D.

For the latter - on Windows 10 b64-bit - I am using following 
options for example:

-shared -L/LIBPATH:c:\\lib  -L//IMPLIB:mylib.lib

In my case I would like stuff from my D code to be exported. I 
found that I need to do following if I want to export a C API.

extern (C) export void myfunc();

I did not find examples of how to export D classes / functions - 
and right now I am getting link errors when trying to export D 
code.
