Hey,

So I'm learning how to use DirectSound, and I'm using the classes in SDKsound.cpp and SDKsound.h to load .wav files. My project compiles ok, but I get linker errors about undefined external symbols. I tried copying the files from the SDK directly into my project folder, but all that did was force me to change my project's character set to unicode, making me cast all my strings with (LPWCSTR) (or something like that), and I still ended up with linker errors (even more actually). So, anyone who uses SDKsound know what's going on? Here is the build record:

Any help is GREATLY appreciated. And soory if this is the wrong forum.

Err.... anyone? I mean someone has to use SDKsound.h, dont they?

Well, from the output it looks like you do not compile the SDKsound.cpp with your project, e.g. it is not included in your project - there's only a main.cpp and the missing stuff is implemented in SDKsound.cpp.

SDKsound.cpp needs to be part of the project? At first I had tried including it like this:


and adding it's directory to the compiler options. I tried putting it directly in the project, and I remember getting simmilar errors, but I'll try again and see what I get.

Edit: I copied SDKsound.cpp and SDKsound.h directly into my project and included it like like this: #include "SDKsound.h", and I still get basically the same errors:

Now all that is left is to add DXUT.h and DXUT.cpp from the core folder to your project.

Allright, I'm away from my home computerright now, but I'll try it when I get home. Why do these files need to be directly placed in the project? Why that can't be linked(right word?) to remotely(again, right word?) like #include <stdio.h>?

That's the way C++ works :) The .h files define the interface while the .cpp implement it. The separation is there as compiling large chunks of code can take quite some time (as compared to languages like C#). Technically .cpp can be included just like .h files but this might result in global variable clashes and not really worth it anyway.

Ok, so I added DUXT.cpp and DXUT.h, causing me to change my project build to unicdoe (trying to avoid that, but w/e), then it complained about not having SDKwavefile(.cpp & .h), so I added those, and then I get these errors:

Also, to the whole header file question, so files that you link to with angle brakets <> instead of quotes "" like stdio.h don't have sperate .cpp files containing their implementation? I.e., there is no file called stdio.cpp that stdio.h uses, it has everything it needs? Also, if .cpp files can be included just like .h files, then isn't the .h extension just a formality to let the user know this type of file should be linked to?

Hi,

Are you linking to dsound.lib?

:)

Yes, there are the libraries I am linking to:

d3d9.lib d3dx9.lib winmm.lib dsound.lib dxguid.lib dxerr9.lib comctl32.lib

Rather than trying to get all of this to work manually, there is an easier way. Start the DirectX Sample Brower application. Scroll down to the Empty Project sample. Click "Install Project". You will be prompted for a name for your project. It will then generate a project complete with all of the files you need to use DXUT. The SDKsound* files are actually installed as DXUTsound*, but the classes are the same.

If you do that, you won't need to mess around with trying to get all the right .h/.cpp files into your project and you should be able to just compile and run the stub application. Then you can add whatever code you want in the appropriate stubs and away you go.
