I'm getting started with DirectX and at this point am just trying to get code to
compile. I'm getting 'Symbol Undefined: _Direct3dCreate9 4' which I understand
means that I need to link in a library. So, my question is: Which one do I need
to link in? I've already downloaded the DirectX SDK and gotten a bunch of .lib
files from that, but I can't seem to find one that works for this.

Thanks in advance.

You need to import d3d9.dll (usually located in c:\windows\system32) with
implib.exe. To use implib you need to download the Basic Utilities zip in the
download section of Digital Mars. On the other hand, the d3dx9.lib (which
includes the D3DX API) is supplied only as static library so implib doens't
helps here.
