mex compiler setup for Simulink StateFlow

Hello.

I'm trying to use Simulink StateFlow.

But there is problem of compiler.

I setup the compiler using:

>> mex -setup

Welcome to mex -setup.  This utility will help you set up  
a default compiler.  For a list of supported compilers, see  
http://www.mathworks.com/support/compilers/R2013a/win64.html 

Please choose your compiler for building MEX-files: 

Would you like mex to locate installed compilers [y]/n? y

Select a compiler: 
[1] Microsoft Visual C++ 2012 in C:\Program Files (x86)\Microsoft Visual Studio 11.0 

[0] None 

Compiler: 1

Please verify your choices: 

Compiler: Microsoft Visual C++ 2012  
Location: C:\Program Files (x86)\Microsoft Visual Studio 11.0 

Are these correct [y]/n? y

  Warning: MEX-files generated using Microsoft Visual C++ 2012 require 
           that Microsoft Visual Studio 2012 run-time libraries be

           If you plan to redistribute your MEX-files to other MATLAB 
           users, be sure that they have the run-time libraries.

However, when I run the StateFlow model I made, the error message appears.

"Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks.
Use 'mex -setup' to select a supported C-compiler."

How can I solve this problem?

I also tried to install Microsoft SDK 7.1 to use this compiler.

However, I failed installing SDK 7.1. I don't know the reason.

The strange thing is that the example of StateFlow runs successful without any error message.

[Useok]

The version is R2013a

[Useok]

Problem is solved.

As mentioned from Friedrich and Paul Metcalf, it was a bug.

Can be patched from: http://www.mathworks.co.kr/support/bugreports/931218

Thank you!

I don't know if this will work, but try booting MATLAB in administrator mode (right click and select run as administrator) then repeat the mex -setup...

Hi Paul, I tried to run in the Administrator Mode. I got the same message: Any suggestion? The link you put is from Korea!!

No supported SDK or compiler was found on this computer. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2013a/win64.html

Error using mex (line 206) Unable to complete successfully.

Thank you so much! It works!

I'm having an identical issue with Matlab/Simulink R2013a. However, I'm using Visual Studio 10.0 from the Microsoft SDK 7.1. Here's what the mex -setup session looks like:

I've tried applying the patch you linked to, and it didn't help at all. I posit that the patch only fixed the problem for Visual Studio 11.0, not for 10.0. Or I didn't apply it correctly. :)

I'm happy to do any troubleshooting or run any extra tests if you think it'll help.

Hello ,

I have this issue in R2008b version, can i use the same thing.
