What did I do wrong? What could be missing?

you are running .sh script instead of .bat on windows. and looks 
like this samples a bit outdated, though d2html looks fine.

Thank you for the answer.

This is the contents of the build.bat, which is shipped with the 
D instalation:

..\..\windows\bin\shell all.sh

Can you tell me, what is outdated?

pi sample at least has compile errors.

no, i mean its not get updated to fetch with phobos changes. 
though it should be simple to fix.

do you really need that pi exapmle? i see it's the only exapmle 
which fails to build, others works fine.

I badly need to build a working COM server, so I can extend the 
already existing and mature VB6 project. In time I'd like to 
migrate into D entirely, this will be a just a small first step.

This reminded me to come back to this (I was commenting on stack 
overflow a few days ago too). Spun up an XP box and now I can 
reproduce your problem.

Strangely, the same exe and dll work on Vista computer still! But 
at least I can see the problem on XP so maybe I can help figure 
this out now....

Aaaand figured it out: actually, the fact it worked on Vista but 
not on XP was the key clue and I'm ashamed I didn't realize this 
earlier.

This comment hints at it too in dserver.d
             // Multiple threads not supported yet


Anyway, D's thread local storage doesn't quite work right on 
Windows XP, and does work beautifully on Vista and up. I don't 
really know why, but that's the way it is. It can cause invalid 
memory accesses...

....And the GUIDs and a couple other variables in the sample are 
thread local! (Back when the sample was written, global variables 
were truly global, like in C. Since then, that's changed, the 
variables are now in thread local storage unless you mark them 
with __gshared, which breaks things...)

So here's the fix: add __gshared to a few places.

dserver.d, line 119 give or take, there's some globals g_cObj etc:

__gshared ULONG g_cObj =0;
__gshared ULONG g_cLock=0;

__gshared HINSTANCE g_hInst;

chello.d, about line 24:


__gshared GUID CLSID_Hello = { 0x30421140, 0, 0, [0xC0, 0, 0, 0, 
0, 0, 0, 0x46] };
__gshared GUID IID_IHello  = { 0x00421140, 0, 0, [0xC0, 0, 0, 0, 
0, 0, 0, 0x46] };


(Actually, those could probably be immutable too, but meh just 
making it work.)


Then recompile, remembering the libraries we talked about on 
stack overflow, and you get a new dll. On my computer, it 
actually came out 100KB smaller too, cool!


Now, chello.exe runs and successfully creates the object.

regsvr32.exe still fails though, on XP (works on Vista), I must 
still be missing something. But this is a lot closer already....

I "fixed" this by commenting out the call to gc_init in 
dserver.d's DllMain (thereabouts line 140). I don't know why it 
would work in dclient but not regsvr, maybe it has to do with 
threads again. Regardless though, comment that out and it 
registers.

Soooo yeah that's kinda messed up that this stuff doesn't just 
work, but at least you can make it work now, hopefully.

let me know if it works on your computer too.
