digitalmars.empire - D version fails to compile

reply Derek Parnell <derek psych.ward> writes:
I just downloaded the D version and used DMD v0.118 to compile it. I get a
lot of errors. And if I use the -w switch there are masses of warnings -
some I note are hiding potential bugs too.

The one error that has stopped me is ...

function std.c.windows.windows.DialogBoxParamA
(HANDLE,char*,HANDLE,int(Windows *)(HANDLE,uint,uint,int),int) does not
match argument types (HANDLE,char[7],HANDLE,int(Windows *)(),int)

The source line in question reads ....

DialogBoxParamA(global.hinst, "InitBox", hwnd, global.lpfnInitDlgProc, 0);

and 'lpfnInitDlgProc' is defined as ...

    FARPROC lpfnInitDlgProc ;

and in std.c.windows.d we find ...

    alias int (*FARPROC)();

Any clues?

Just cast it to the right value. I uploaded a new set of sources that
compiles.

Well that was about as useful as tits of a bull! Of course one has to fix
it to have the 'right' value. But it isn't clear to all and sundry what
that actually would entail. 

I can see that what you have done is added ...

extern (Windows)
{
    alias int function(HANDLE, uint, uint, int) DLGPROC;
}


and changed ...
	FARPROC lpfnInitDlgProc ;
to ...
	DLGPROC lpfnInitDlgProc ;

Just in case you hadn't guessed, that was not an obvious solution to me. 

I take it that the two lines below are equivalent.

    alias int function(HANDLE, uint, uint, int) DLGPROC;
    alias int (*DLGPROC)(HANDLE, uint, uint, int);

I'm guessing the first is the D style and the second is the old C style. I
prefer the D style - it is much more clearer to read and understand.

I would have twigged if the original alias had have been coded as ...

   alias int function() FARPROC;


Anyhow, I made this addition below to empire.d and ran the latest (not
released yet) version of build and it built it without fuss - no makefile
required.

    version(build) {
        pragma(link, "winmm.lib");
        pragma(link, "comdlg32.lib");
        pragma(target, "winemp.exe");
        pragma(build, "empire.rc");
        pragma(main, "winmain.d");
    }

then used ...
  build empire


By the way, empire.rc refers to cursor.bmp and empire.ico which are not in
the distro.

Sorry about that.

A cast would have worked too, in the same manner that C tends to rely on
typedef's to cast function pointer types, but I thought changing FARPROC to
DLGPROC looked a bit nicer.


 I take it that the two lines below are equivalent.

     alias int function(HANDLE, uint, uint, int) DLGPROC;
     alias int (*DLGPROC)(HANDLE, uint, uint, int);

That's right, though D will accept the C style.


 I
 prefer the D style - it is much more clearer to read and understand.


So do I.

    alias int function() FARPROC;

         pragma(build, "empire.rc");
         pragma(main, "winmain.d");
     }

 then used ...
   build empire

 the distro.


Thanks. It's fixed now.

I've just downloaded the source, and can't find any of the numerous bug 
fixes I sent you a while ago.  Did you lose my fixed version, or did I 
mistake your question


 Cool! And just to reiterate, these changes are donated?


for being rhetorical?

I didn't look at them yet as I hadn't seen a reply yet on the copyright
status of the changes. It's nice to make sure all the t's are crossed and
i's are dotted for the copyright issues.

Rest assured the changes are free for you to do whatever you want - 
check in to the official version, claim whatever level of IPR you wish....
