Hi,
In another thread I mentioned that I would convert my game to D. Well all
was good until step 3 of 45672345.
I looked at Walter's empire windows code and noticed that he wrapped the
globals in a struct - so I did too.
(This is when I decided that I had an issue with 'with').
Now here's where my lack of D savvy will show. When I went to refer to the
struct in an other module I simply imported the module that the structure
was declared in. It compiles but won't link.
I get 'Error 42: Symbol Undefined _D4iced6globalS4iced7globals' in the
importing obj module. I've tried every combination of export, extern I
could think of; although I wouldn't have expected to need to. I also tried
declaring the variable public, still no luck.
Any thoughts would be appreciated.
The structure definition and declaration are below.
struct globals {
int Score;
bit Random;
HDC hDCVid, hDCScrn, hDCMem;
HINSTANCE Instant;
HWND hWndStat, hWndEdit, hWndIce;
char GameName[];
int Lives, Screen, Stands, CountDown, Diamonds, TimeOut, Loaded, xScr,
yScr, yText, yChar, xChar, Width, Height;
byte SCRNX, SCRNY, retX, retY, GoodX, GoodY, HIT;
byte[64][64] Scrn;
};
globals global;

Thanks Phill. I got yours working even after I moved the 'globals g' definition to the glbl.d file. The only diference I noted was that you used the module statement at the top of the glbl.d file. So I included it at the top of my file and the problem went away. Now....why?!!! The reat of my files are imported OK without module statements. I thought modulename = filename (less .d) if not specified. Any thoughts?

If you have two files: main.d and imports.d, you probably need to put
both of them in the compile line:
dmd main.d imports.d
I'm guessing this will solve your problem.
Another way of solving this problem is to compile each separately:
dmd imports.d -c
dmd main.d imports.obj
