I have installed the MinGW-w64 compiler but I still get an error message when trying to compile a cc file:
>> mex -setup c
MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.
>> mex -setup c++
Error using mex
No supported compiler was found. You can install the freely available MinGW-w64 C/C++ compiler;

>> mex 'keyInject_setFocus.cc'
Error using mex

The same works fine on Matlab 2017b. Suggestions?

Hi Raphael,
Firstly, make sure that you have installed the complete version of the MinGW compiler from the add-on section of MATLAB, as custom installations of MinGW compiler may not be compatible with MATLAB.
If this issues still persists and is only occurring after restarting MATLAB, here is a workaround.

Hi Raphael,
I understand that you have installed MinGW support package for MATLAB, but are not able to setup mex.
The outputs that you for the commands also suggest the same. As I am not able to reproduce the same at my end, I suggest you contact MathWorks support to resolve the issue.
Thanks
