Overriding a structure with an indirect definition

[Yuri]

Hi Jeremy,

I encountered this error when using Edgar's headers. So that you don't have to look through them, I've extracted the relevant material. In this example, a GUID structure must be overridden differently, depending on whether UNICODE is defined.

Code Select Expand


GUID STRUCT
    Data1   dd
    Data2   dw
    Data3   dw
    Data4   db 8 DUP
ENDS

#define GUID_IID_IShellLinkA <0x000214EE,0,0,<0xC0,0,0,0,0,0,0,0x46>>
#define GUID_IID_IShellLinkW <0x000214F9,0,0,<0xC0,0,0,0,0,0,0,0x46>>

#ifdef UNICODE
    #define GUID_IID_IShellLink GUID_IID_IShellLinkW
#else
    #define GUID_IID_IShellLink GUID_IID_IShellLinkA
#endif


DATA SECTION

IId   GUID    GUID_IID_IShellLink


CODE SECTION

Start:
    xor eax,eax
    ret


This is the error message from GoAsm:

Hi Yuri

Thanks for reporting this.

In order to achieve this, GoAsm needs to look one level deeper into the defines for initialisation information provided when the structure is used.

I can add this, and so I shall come back to you when this has been done.

Hi Yuri

This has now been added in GoAsm (Version 0.56.8).

Jeremy, thanks a lot for both improvements! I very much appreciate that! :U
