    DX error q?

    I got this error while compiling a simple DX program:
    Code:
    Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland
    Error: Unresolved external 'DirectDrawCreateEx' referenced from C:\COMP\DIRECTDRAWSPRITES.OBJ
    What does it mean, and how do I fix it? Thanks all !

    "Unresolved external" means its looking for a function (namely "DirectDrawCreateEx"), but it can't find it. If your #including the right directx files, make your your linking with the right object files.

    In VC++, I have to tell the compiler to use a folder that has lots of .o and .obj files for a library I downloaded. Yours probably does too, but I have no idea how.

    Most compilers that I know of keep all that stuff in the Lib folder, so possibly you could try putting the Lib files from directX into that?

    Although Salem might tell you off for messing with files in your compilers directory, so you could check the help files for your compiler on how to link with other files in folders. Hope that helps

    Ah, for DirectX, you need to be linking various .lib files.... first, check to make sure that the directX directory is included in the directories where MSVC looks for headers/libraries. If you had MSVC before you installed the DirectX SDK (you did that, right?), the DX SDK should have taken care of that for you. So, in project->settings->link->project options, add the following .libs (you don't need them all now, but you probably will in the future of your program)
    Code:
    dxguid.lib       //ummm...I forgot what this one was, but it's important
    comctl32.lib   //for common controls...not dx
    d3d9.lib        //for d3d
    d3dx9.lib     //for d3dx stuff
    dinput8.lib  //for direct input
    Away.

    d3dx9.lib     //for d3dx stuff
    dinput8.lib  //for direct input
    Just so you know, I'm using Borland. Anyway, to get it working, you have to create a bcc32.cfg file with the contents:
    Code:
    -I"D:\Compilers\Borland\Include"
    -L"D:\Compilers\Borland\Lib"
    Considering that's where Borland is. So would I add this to the end?
    Code:
    -I"D:\DXSDK\Include"
    -L"D:\DXSDK\Lib"
    And yes, I did install the DX SDK .

    Well, bcc32.cfg worked fine, but..... the real problem was with the turbo linker. It uses ilink32.cfg, which currently has this:

    Code:
    -L"D:\Compilers\Borland\Lib"
    I added the DX lib folder, so it now looks like this:
    Code:
    -L"D:\Compilers\Borland\Lib"
    -L"D:\DXSDK\Lib"
    Without the second lib declaration, the first error I had is created. With this new addition, here is what I get:

    Code:
    Borland C++ Compiler Blahblah
    ........
    Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland
    Fatal: Expected an option: LD:\DXSDK\Lib
    I get no errors from the actual compiler. Thanks all !

    EDIT:

    so bcc32.cfg has:
    Code:
    -I"D:\Compilers\Borland\Include"
    -L"D:\Compilers\Borland\Lib"
    -I"D:\DXSDK\Include"
    -L"D:\DXSDK\Lib"
    and ilink32.cfg has:
    Code:
    -L"D:\Compilers\Borland\Lib"
    -L"D:\DXSDK\Lib"

    Try (includes path to psdk which you'll probably want anyway):
    bcc32.cfg
    -I"D:\Compilers\Borland\Include;D:\DXSDK\Include "
    -L"D:\Compilers\Borland\lib;D:\Compilers\Borland\li b\psdk;D:\DXSDK\lib"
    ilink32.cfg
    -L"D:\Compilers\Borland\lib;D:\Compilers\Borland\li b\psdk;D:\DXSDK\lib"
    edit: each -I and -L should be a complete line; the 'quote' appears to have wrapped it. Also, have a quick read of this faq, if you haven't already done so.

    ARGHHH.

    -I"D:\Compilers\Borland\Include;D:\DXSDK\Include "
    -L"D:\Compilers\Borland\lib;D:\Compilers\Borland\li b\psdk;D:\DXSDK\lib"

    That is my bcc32.cfg file. ILINK32 is currently:
    -L"D:\Compilers\Borland\lib;D:\Compilers\Borland\li b\psdk;D:\DXSDK\Lib"

    What is wrong!!!!!! ARGHHH. Once again, I get "Unresolved External: DirectDrawCreateEx" . I don't get what is wrong! I've quadruple checked the locations, and I really dont get what is wrong! Sorry, but does ANYONE have a solution?

    Migrate to another compiler/linker I know that with MSVC you can do a #pragma to link libs (my preferred method), or you can link them in the link tab under options.

    Also, to all those smarter people out there, (off topic) are #pragma's all compiler-specific or are only some? I never did really understand about that...

    **EDIT**
    Is the path you're using case sensitive? It usually doesn't matter, but I hate when I overlook something like that when it does matter.
    Just Google It. √

    No, the location is correct. And I think most pragmas are comp. specific. And im sticking with Borland

    Maybe your SDK didn't come with the proper libs, or they are incomplete, or something got deleted/corrupted, etc. Have you tried reinstalling the SDK? Or maybe DirectDraw isn't included in the DX9 SDK? Who knows...
