Can't find DX8.1 Version

Recommended Posts

I just reinstalled windows (XP), and installed the 8.1 SDK instead of the 8.0a SDK I used before. Unfortunately, now all my programs come up with the warning: c:\lang\dx81sdk\include\dinput.h: DIRECTINPUT_VERSION undefined. Defaulting to version 0x0800 The downside of this is: DrawPrimitive now fails to work. Have I done something wrong in installing the SDK??? Any Ideas? I installed Visual C++ first. DX8.1 SDK second. - it seems to have linked in OK. Thanks for all assistance Simon

The warning you get is "normal". All SDK headers define their version like this:


The difference with DirectInput is that it outputs a warning message when the version is undefined. Just add this before including dinput.h:


and the warning will go away.

As for DrawPrimitive failing, this has nothing to do with DirectInput and you have to be more specific to get help.

Try installing/switching to debug D3D runtime and run your program under debugger. See if D3D complains about anything.

Edit: fixed code tags.
