Reply to Michael P.,
I'm getting an undefined reference error with Derelict and SDL.
I tried to create an SDLImage class, but I got an error when the files
try to link together.
I've attached the two .d files in a rar.
I compiled with "build imagetest".
I have Bud 3.04, and DMD version 1.036.
I have compiled other SDL programs, so everything is set up properly
with Derelict.

what are the error messages? (copy/pates)

Error 42: Symbol Undefined _D9SDLImages11SDL_Imagess5_dtorMFZv
The linker is expecting to find a destructor for your SDLImagess class
in the object file, but it's not there. Your problem is on line 44 of
SDLImages.d:
//Destructor
~this();
Your destructor is declared, but not implemented -- hence the error. If
you've got nothing to do in the destructor, either implement an empty one:
~this() {}
Or take it out entirely, in which case the compiler will generate a
default destructor for you.
IMO, this should really be a compiler error. I'm surprised it isn't.
