1. I installed matlab2012b in windows7.

2. Compiler : Microsoft visual C++ 2008 Epress edition

3. Java version 1.7.0_02 Java<TM> SE Runtime Environment<build 1.7.0-02-b13>

I have all the above software in my PC.

But when I am trying to run the model I was getting the error.

Code Error: Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks.

Model Error: Error using construct_error (line 108) Library failed to build. Cannot continue build process. Use 'mex -setup' to select a supported C-compiler.

I try to run the mex -setup the following information is displayed. 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/R2012b/win64.html

I couldn't see any compiler's information.

Please tell me how to resolve this issue.

2008 Express is simply not one of the supported compilers for R2012b in 64 bit mode. You can use 2008 Professional or you install SDK7.1. Click on the link it supplied, http://www.mathworks.com/support/compilers/R2012b/win64.html for links to download 7.1

The "Express editions" of Microsoft Visual Studio have severe limitations. Perhaps using it's compiler outside of Visual Studio, like another program trying to use the compiler, is not allowed. You may have to upgrade from the free Express edition to a "pay" edition.

After installing 2008 Professional it worked. Thank you.

I have one more problem.

In 2007b with mex -setup complier is not shown even after installing 2008 Professional. But in 2012b it is working fine.

What could be the reason?
