Answer 1

The d3dx9.h legacy utility library for Direct3D 9 is only available in the DirectX SDK. June 2010 is the last release of the DirectX SDK and is on Microsoft Downloads --although not for long per this .

Note that with Visual C++ 2012 or later, you must take special care when referencing the legacy DirectX SDK include/lib paths because they contain headers older than the Windows 8.x SDK/Windows 10 SDK used by Visual C++ so they can cause conflicts. Details on covered at the bottom of this page .

D3DX9, D3DX10, D3DX11, and the DirectX SDK are all deprecated. See this blog post .

The general recommendation is to NOT use Direct3D 9 at all and instead use Direct3D 11 or later. All required Direct3D includes/libs for DirectX 11 & DirectX 12 are included in the Windows SDK.

For a list of modern replacements for the contents in the old D3D9X/D3DX10/D3DX11 utility libraries, see this blog post .
