Ah, I see, that makes sense. And it now compiles correctly, thanks.

am trying to set up a function that would pass the function pointers
from C to D, and DMD refuses to compile it:
If I have the function pointer struct with D calling convention
pointers, like this:
struct S_FrontendFunctions
I'm trying to implement the function pointer system right now, and it
seems to work on the C side, but not D. I assume I'm missing some kind
of syntax here. I have these global variables:
struct S_FrontendFunctions {
void function() RedrawScreen;
void function(const
Oh, so structs themselves are only definitions and not global
variables, I see. Thanks.

Yes, this is a library, so a main() there would be rather pointless.
However, it seems that on many occasions compilers will simply not
acknowledge anything without one, so I guess at least a declaration is
in order... I'll have to try that out once I get back on Windows.
Meanwhile, on Linux, I am

So, now my (static) library nearly links in Win32. There is only one
link error, and apparently it's generated by phobos:
..\lib\phobos.lib(dmain2)
Error 42: Symbol Undefined __end
Any clues about what is happening? Admittedly, that phobos.lib is from

I see. Well, I guess I'll have to stick to static ones until this gets
sorted out.

No no. It's the other way round. Shuffle() is in the library
(backend). PlaySound() is in the executable (frontend). Since I don't
want the library to be dependent on any sound libraries, I can't have
PlaySound() in it. And there is no other way that I can think of to
