MATLAB 2016a cannot locate gcc compiler

I'm using MATLAB 2016a on a Macbook Pro running OS X El Capitan. Command Line Tools are installed:

MacBook-Pro:~ neergaard$ gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
MacBook-Pro:~ neergaard$

However, MEX cannot seem to find gcc:

>> mex -setup
Error using mex
No supported compiler or SDK was found. For options, visit http://www.mathworks.com/support/compilers/R2016a/maci64.html.
>> gcc -setup
Undefined function or variable 'gcc'.

Is there something I can do to 'force' MEX to look specific places?

Answer 1

[Elisa Boatti]

try

setenv('MW_MINGW64_LOC',folder)

where folder is the location where MINGW is installed

MINGW is not used on OS-X: it is only for MS Windows.

Try out

   mex -setup

Forgot to mention I've already tried that. Edited original post.
