I'm getting this error (Error 42: Symbol Undefined _DirectDrawCreate@12) from the linker, despite the fact that I'm including ddraw.lib (which I generated from c:\windows\system32\ddraw.dll using implib (Digital Mars Import Library Manager Version 7.6B1n)) in the compile-line.

Compile line:

sc.exe -mn win.cpp noctis.cpp noctis-0.cpp noctis-1.cpp noctis.def user32.lib kernel32.lib winmm.lib ddrawex.lib advapi32.lib shell32.lib ddraw.lib gdi32.lib -oNoctis_D -dDEBUGBUILD -gp -s -Ju -L/co/ma -g -cpp | more

(No, all those libs aren't needed, but since this didn't want to work, I added anything that looked like it might remotely help)

The output after compilation is:
-----------------

 Error 42: Symbol Undefined _DirectDrawCreate@12

--- errorlevel 1

-----------------

DirectDrawCreate does indeed exist in ddraw.dll, and it looks like it's in the lib as well, or so I'm guessing since it's in the text in the lib when I look at it in a hex-editor, though the text does not have a _ before DirectDrawCreate, or an @12 after it, anywhere ("DirectDrawCreate" is in the lib file several times).

These are in the includes:
#include <initguid.h>
#include <ddraw.h>
#include <winuser.h>

(P.S. MSDN says that I only need to import ddraw.h and include ddraw.lib in the libraries to use DirectDrawCreate. http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/ddraw7/directdraw7/ddref_3h6f.asp )

I was having a problem where IID_IDirectDraw2 didn't exist before, but solved it by adding #include <initguid.h> there... #define INITGUID didn't work (I tried that first), but #include <initguid.h> did.

Also, I had to define DDSURFACEDESC2 (A struct) myself in order to use it, since it wasn't in ddraw.h either.

Also, IID_IDirectDraw7 didn't (doesn't) seem to exist either, and I had (have) no effective way to fix that, since I would have to know the massively long number it's made from....

-----

I thought that the problem might have been the ddraw header file being out of date, so I downloaded the DirectX SDK, and installed it, and took the ddraw.h from there and threw it in the program source folder, and changed the #include <ddraw.h> to #include "ddraw.h" - And, well, DDSURFACEDESC2 exists now, so I commented out mine, but it still won't link, still giving that error about _DirectDrawCreate@12. :/

I tried implib /system, too, by the way, and didn't notice any difference. Also tried running implib on a ddraw.def I got from http://programming.ccp14.ac.uk/ftp-mirror/programming/mingw32/home/janjaap/mingw32/platform-SDK/def/ddraw.def (found via google), which didn't solve the linking problem either.

(I managed to get it to link by hex-editing the .lib to say _irectDrawCreate, and changing the function name in the ddraw.h and the source files which use it to irectDrawCreate (no D), but of course, the program won't run. :P)

I suppose the question I should be asking is "How do I make DM stop adding that _ before the function name and the @12 after the function name, because the .dll and the .lib don't have it?"

Oh, P.S. I tried fiddling with the declaration of DirectDrawCreate in ddraw.h (changing it from WINAMP to __cdecl, __stdcall, FAR PASCAL, etc, but it didn't help. What? I was desparate!).

(I also tried searching old posts here, now that I have mozilla set up to read from the news-server, but I didn't find much except something that indicated that someone might have to send me a ddraw.lib to fix the problem, since apparently implib doesn't work on 100% of DLLs or something? (It seemed to work fine on all the other (system) DLLs I used it on, and I didn't use /system... Oh well.)

Which IMPLIB did you use?

Haven't heard of atomz before, but I spent about 3 hours googling and trying to figure this out.

I also tried (after making that post) VCPP6SE's 'link /lib /convert ddraw.lib' on the VCPP6SE version of ddraw.lib, followed by 'coff2omf' (From Borland C++ 5.5, since I didn't see the DM version for download anywhere) - The resulting lib file was about 2 KB (The ones made by implib were 4 KB when I imported from the ddraw.def which I mentioned and 4.5 KB when I imported from ddraw.dll), and didn't work any better than the others (i.e. I got the same error message from the linker after I tried it).

Try this and see what it does for you.

There have been others in the past that worked with DirectX/Direct Draw and got it working.

Yes I did a fair while ago, in fact I believe I
had the same problem, and when I posted on
this group my problem was solved, by some
good soul who sent me two LIB's, that he created.

I beleive Nic Tiger was his name.
I dont know that I have permission to pass these
on though.

what can I do?

Phill.
