digitalmars.D.learn - Making a .lib in D

I'm trying to compile a .d and make a .lib but the .lib seems to be missing
functions. I verified the behavior by generating a .lst and seeing that some
functions from the .d weren't in the .lst.

Specifically, I'm trying to compile a .lib for sdl_mixer. I got SDL_mixer.dll
from libsdl.org and 'sdl_mixer.d' from D-Porting. I ran 'dmd -c SDL_mixer.d' to
make sdl_mixer.obj, then 'lib -c -l sdl_mixer sdl_mixer.obj' to make the lib.
But then when I compile a simple program, at linking, I get errors for undefined
symbols. The functions mentioned are (prototyped at least) in sdl_mixer.d.

Is there an option in the compiler to keep the functions that are prototyped but
not defined? Or do I need to pass an option with the .dll name so that it can
verify that those functions really exist?

Thanks,

I really wish there were.  What you'll have to do instead is have two 
modules: sdl_mixer.d and sdl_mixer_imports.d.  Copy all the function 
prototypes of the undefined functions to sdl_mixer_imports.d.  place an 
"import sdl_mixer_imports;" statement at the top of sdl_mixer.d.  Compile 
_only_ sdl_mixer.d; do not compile sdl_mixer_imports.d.  Then make your lib. 
Those references should hopefully appear in your lib file.

You need to import the .dll in a .lib using 'lib', not creating a D module. 
Check the docs for the lib tool to know how to use it.

I don't see any mention of dll's on the doc page for 'lib'. Where does it talk
about this? Oh wait, I think I need to run COFF2OMF on the .lib I have.

My bad, sorry. It's implib, like Jarrett said.
