problem when i starting simulink

i made some mini model and put there blocks off :MATLAB FUNCTION,AUDIO RECIVE

and in the matlab function i wrote:

function y = fcn(u)
%#codegen
y = u;
a=wavread('moho.wav');
wavplay=(a);
end

that mean that i trying to active this file that make sound

and when i start to code to c its write this problem:*_

The specified code generation target for model 'untitled' cannot be used with a variable-step solver. You must either configure the solver options for a fixed-step solver with an appropriate integration algorithm, or select a target that supports a variable-step solver, such as rsim.tlc. Click Open to launch the configuration dialog. Modify either the solver options on the Solver page or the system target file on the Code Generation page.

That means, you should change the step time of your solver from variable step to fixed step (in configuration parameters)

yes i did this and then when i was trying to start : code->c/c++ code-

>build model its write to me : Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler.

[Azzi Abdelmalek]

Then, in Matlab windows command type

mex -setup

and choose your compiler
