AN ERROR THAT IS REALLY PISSING ME OFF!!!

[Warmaster199]

Ok, this is it! I am trying to create a DirectX 3D Engine, but I am having some problems creating it using VC++ 5.0. My 3 problem functions are:

D3DXVec3Normalize, D3DXVec3TransformNormal, D3DXMatrixMultiply

When my program compiles, it complains: "Unresolved External Reference" and the name of the 3 function calls in the file called I3DCorona.cpp. What's going on? How can I fix this?

Do you have a header to correspond to those functions, and has it been included into your source file (the one you're calling the functions from)?

[Warmaster199]

Yes, it has been declared in an include file. The file is:

#include<D3DXMaths.h>

It contains the functions, but I can't use them. I can open the header in Visual C(under external dependencies) and explore it. Those functions are there, and the file IS included.

do I have to re-declare the sub as external?[EX: extern D3DXVec3Normalize(.......)]?

I can't use my VC5 compiler to test it right now, my friend is borrowing my CD(burned) for VB5.
PLEASE HELP!

It depends...are the function bodies actually in the header file? Or are they in a separate source file?

If they're separate, then you need to link with the library or an object file for that source code.

[Warmaster199]

The functions are called in the include file, ie: Not in file, just called. This is what it looks like in the D3DXMath.h include file:

D3DXVECTOR3* WINAPI D3DXVec3Normalize( D3DXVECTOR3 *pOut, const D3DXVECTOR3 *pV );

All the functions that worked previously were inline functions that had their "bodies" in the include file. I think I know the problem. I think I've got to include the library too. As I said earier, I can't compile or test anything as my compiler on a CD that I let my friend borrow.

If this works, Thank you in advance

It works! I'm going to continue working...

You need a web graphic of 50x50 pixels, under some size limit...You can upload them in your options.
