Problems with the compiler when running gravity_windup.slx example from sparkfun_r​edbot_bloc​k_lib

I try to compile and run an example code gravity_windup.slx from sparkfun_redbot_block_lib. The error shown is:

No supported compiler or SDK was found. You can install the freely available MinGW-w64 C/C++ compiler;
see Install MinGW-w64 Compiler. For more options, see 
http://www.mathworks.com/support/compilers/R2015b/win64.html.

When I try to upload the code to the board, I get the following message in the diagnostic viewer:

This is what I have under Code --> C/C++ Code --> Code Generation:

Finally, if I click on Validate from Code Generation--> Build option, I get a "passed" message for the Toolchain. See below:

The cpp files of the project do not seem to be compiled. See image below:

I use:

MATLAB Version: 8.6.0.267246 (R2015b)
MATLAB License Number: ••••••
Operating System: Microsoft Windows 7 Enterprise  Version 6.1 (Build 7601: Service Pack 1)
Java Version: Java 1.7.0_60-b19 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

Any ideas for fixing this problem? Thanks in advance.

It is common for the build process to require a compiler on the host to put together the header files and some other items. You will need to install one of the compilers listed in the link.

I have installed the compiler, and change it as the default toolchain. However, no change.

Have you tried doing mex setup using the following command?

>> mex -setup

This should tell you what compiler is being used by MATLAB if any.

[Diana Saplacan]

Yes, I run the cmd. After installing the compiler, I get: MEX configured to use 'MinGW64 Compiler (C)' for C language compilation. Warning: The MATLAB C and Fortran API has changed to support MATLAB variables with more than 2^32-1 elements. In the near future you will be required to update your code to utilize the new API. You can find more information about this at: http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.

To choose a different language, select one from the following: mex -setup C++ mex -setup FORTRAN.

However, the problem that I have now is the following error, which I am not sure on what it is depending on.
