digitalmars.D - How do you use C based libs with D?

Hi, this is a bit related to my post regarding MingW compatibility.

As D uses Optilink (AFAIU) this implies that all C based code needs to 
be compiled with DMC?

Not that I don't like DMC (I like it a lot) but I always had problems 
(or it requires a bunch of work) to get open-source projects 
compileable with it.

How do you deal with this?

It works without much hassle at all if you dynamically link the
library. That's what I do when using other people's C libs. (For my
own, I'll just recompile with dmc on Windows. On Linux, it just works,
since they all use the same linker anyway.)

Hi, yes, that's the fallback. Either getting all this stuff as DLL 
already or having to make one.

On the other hand I try to avoid "DLL hell" to keep the support costs 
as low as possible.

You could just bundle the correct DLL directly in with your exe, in the same 
directory.

(Or convince the OSS devs to support DMC ;) )

I deal the way you say: some compiles nice, some requires (lot) of work, and
some are just impossible to compile, so I use dll.

Is there particular reason you avoid using dll's?

Produce static libraries in mingw as usual(no need to recompile with DMC 
or other compiler).
Produce shared library from these static libraries with mingw by linking 
all of them in one DLL.
Apply implib tool on obtained DLL.
Link obtained import library with the target.
Place the DLL in the exact private folder where your executable resides 
to avoid DLL hell.
