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;

I dont think its a problem with the linker, maybe you
have just overlooked something.

Ive attached a simple example.

Phill.

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

I'm using DIDE.

It compiles fine, I just get a linker error.

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?

When you made the module with the struct in it, did
you go:
File-> New File Into Project
or just
File-> New
?

I dont know, I only put that there to look fancy lol
it works either way with mine.
I am not familiar with the way that the 'module'
thing works, or whether you have to compile it
in a similar way to Java's packages.

Im waiting for Mathew's book. :o))
Or a tutorial to be written.

I also use DIDE.
See my other post, maybe it can help.

Phill.

Don't worry it's in the project (file new into project)

Do you have a command line? Have you tried it?

Sorry I was unclear, but I'm talking about a linker error. If both files aren't compiled, I don't think it will link. Your problem might be elsewhere, but without entire files I can only guess what the problem is.


If you haven't got it to work yet, you have some options:

1) Post the whole files of source code so that the rest of us aren't fumbling around in the dark.

2) Try compiling at the command line. Or by using a batch file. I have nothing against using DIDE; I use it all the time for editing files. But that doesn't prevent me from using the commmand line, batch files, or makefiles. I'm flexible.

Thanks,

after looking at Phills source, I noticed that the importeded module had a specific module statement, so I included on in mine.  That fixed the problem.

All files were compiling and the only thing I can thing of is that I named the file in uppercase.
