How can compile in C/C++ the lpc funciton ?

I am trying to compile the lpc function (Linear Predicitve Coding) in C/C++ to later include it in a CSS project in order to implement it into a Texas instrument DSP board. The LPC function can't be compile because I am getting this error: "The function 'lpc' is not supported for standalone code generation.". I did a bit of research and I understood why I am getting that. But is there a work around ? (coder.extrinsic() is not an option as I need to implement it on a DSP board later.) By looking inside the lpc function (type lpc) we can understand what is going on inside it. So why can't we compile it in C/C++ ?
