Convert Mathlab to c/c++ convert issue

I have installed matlab version 2012b(full installation) and Microsoft Windows SDK 7.1 in my PC. I have set compiler using this "mbuild" command (set successfully). After I try to convert very simple matlab code to c/c++ code. But I am getting following error like screenshot

Any one can please help me? Thanks in advance

I think it is because a and b are undefined. Usually you call it like for example sum_of_two_numbers(4,7). Just like the C code:

int sum;

int ss2n(int a, int b)

{

    sum = a + b; 
    return sum;

}

When you call the function you supply the values of a and b, compute the result and put it in sum and return that.

Can you try:

mex -setup

rather than mbuild? The command mbuild is for MATLAB Compiler rather than MATLAB Coder.
