Change include paths + Visual Studio

[Tischnoetentoet]

Hi all,

I am creating a sound engine in visual studio (.net 2003). Well, I have to include <dsound.h>. I have installed the directx sdk, but when I include <dsound.h>, it includes a film from visual studio\prerelease\.

Can I set the include directory of the directx header files???

Thanks!

Hi,

you can either set local include paths for your current project and/or global for alle projects. There you simply need to add your DirectX include folder and move it prior to the SDK list entry. Thats all.

Here's the position where you can find the options (I needed to translate from german, so your menu entries may have different names):
(Menu) Extras -> Options -> (Dialog) Projects -> VC++ Directories : Set Directory Type to Include Directories and add your directory

Project only:
(Popup Menu) Project Properties -> (Dialog) Configuration -> C/C++ -> Common : Additional Include Directories

Good luck!

well, it already is in the main settings. It is the directory at the top (so I guess directx inserted it there already)

I also tried to add the project specific option (adding extra include path), but both options didn't work!

Note: I first started the project, and then I installed DirectX SDK. That should be no problem, right?

Yes, usually does DirectX SDK does this for you... And installing the SDK after creating the project isn't a problem (or, shouldn't).
Did you check the DirectX include directory for dsound.h? Maybe the file got corrupted or lost, however this may have happened.

[Tischnoetentoet]

well, strange. The white edit control above my document says the location of the <dsound.h> is microsoft visual studio .net\vc7\platformsdk\include\prerelease\dsound.h

But when I compile, there are a lot of errors in the dsound.h. The filename is then:
e:\directx\Include\dsound.h

very weird, but it get's the right file now (at least, i guess)

But why are all the compiling errors??

DirectX\Include\dsound.h(230): error C2501: 'LPCWAVEFORMATEX' : missing storage-class or type specifiers
DirectX\Include\dsound.h(349): error C2146: syntax error : missing ';' before identifier 'lpwfxFormat'


Thanks for the help so far!

This is quite common, MSDEV somehow first searches it's "well known" include directories when using the "Open xy.h" command, somehow ignoring the include directory list.
About the compile errors, LPCWAVEFORMATEX is a type defination of dsound.h for a const WAVEFORMATEX* structure pointer; it usually should be avaible. Also it should have been defined there...
Quite at the beginning of the dsound.h file should stand the following lines:

//
// Compatibility typedefs
//

#ifndef _LPCWAVEFORMATEX_DEFINED
#define _LPCWAVEFORMATEX_DEFINED
typedef const WAVEFORMATEX *LPCWAVEFORMATEX;
#endif // _LPCWAVEFORMATEX_DEFINED

Maybe a defination miss-match in your project?

[Tischnoetentoet]

no, all errors occure in the dsound.h

I also linked dsound.lib to my project!

and the list with errors is long, very long!

[Takeru Koushirou]

Hmm, thats strange. Can you post your dsound.h so I can have a look at it?
Also, did you change some compiler settings?

[Tischnoetentoet]

sorry to spend your time!

I was using
DirectSound8 m_pdsObject;
and it should be
LPDIRECTSOUND8 m_pdsObject;

Thanks for all the help!

Ah, IC, that's okay then ^^ Np! Good luck with your project!
