I am attempting to translate and rotate a wireframe cube in dx9 and c++.I have done research on matrices and toymaker's site and some gamedev's old postings.I am able to get vs 2010 to compile my code but I get a link2019 error. Here is my error, I am pretty sure I have linked all the proper headers and libraries.
>triangledx9.obj : error LNK2019: unresolved external symbol _D3DXMatrixMultiply@12 referenced in function "void __cdecl SetupMatrices(void)" (?SetupMatrices@@YAXXZ)

here is the code I am having trouble with.

float x=10.0f,y=10.0f,z=5.0f,r=D3DX_PI/2.0;
void SetupMatrices()
{
D3DXMATRIX matWorld;
D3DXMATRIX matTemp;
D3DXMatrixTranslation( &matWorld, x, y, z );
D3DXMatrixRotationY( &matTemp, r );
D3DXMatrixMultiply( &matWorld, &matWorld, &matTemp );
D3DXMatrixTranslation( &matTemp, x, y, z );
D3DXMatrixMultiply( &matWorld, &matWorld, &matTemp );
d3ddev->SetTransform( D3DTS_WORLD, &matWorld );
}

I will continue to work on this problem.

Did you add d3dx9.lib to your linker inputs?

[phil67rpg]

yes I did

[frob]

The error message implies that you did not correctly add it.

The error message is that the linker is looking for functions, but cannot find them. The functions are in d3dx9.lib.

thanks for all the help,I did get the problem resolved.
