Matlab 2014b mex switch C compiler from XCode Clang to GCC on Mac

I typed

mex -setup C

in MATLAB 2014b and it shows

MEX configured to use 'Xcode with Clang' for C language compilation.

It doesn't give me any options to select. I am sure I have installed GCC on my Mac.

I want to unlink the Xcode and switch the compiler to GCC. Can somebody tell me how to do that?

thanks,

Sorry, MEX only supports Xcode/Clang on Mac. See http://www.mathworks.com/support/compilers/R2014b/index.html?sec=maci64

Thanks, it helps me save my time.
