Can't create a .dll from Matlab Coder

I am trying to convert some matlab code into a c dynamic library (.dll) using the Matlab Coder tool. I'm trying it on some simple sample code, but I keep getting the same error which I can't find a solution to.

My code is:

function y = lbryTest(x, z) %#codegen
%QUICKTEST Summary of this function goes here
%   Detailed explanation goes here
y = 1.0;
a = x + z;
b = x * a;
y = b/3 + y;
end

I've tried using the app version of coder as well as the command: codegen -config:dll lbryTest -args {2.0, 5.0} and the build log, including the error, is:

I can make a .lib from this code, but I need a .dll, which is proving difficult. It looks like I am missing some object file or matlab can't find it, but I don't know what to do about it.

credit to Ryan Livingston for this suggestion, which I am turning into an official answer

The file lccstub.c (compiled to lccstub.obj) isn't on your machine, when it should be. To fix it, you should install a supported compiler for Matlab.

Windows SDK 7.1 is available for free from here
