How to setup C/C++ Compiler for code generation using MATLAB Coder for MATLAB R2015b?

I am seeing a Code 2 build error when trying to generate code using MATLAB Coder. Why am I seeing this? Is it because I don't have a C/C++ compiler installed? If so, how do I install one for MATLAB R2015b to setup code generation using MATLAB Coder?

Also, can I generate code for multiple entry point functions?

Yes, this error occurs either because there is no C/C++ Compiler installed, or there is one installed and it has not been setup for code generation in MATLAB. Please find a list of supported compilers for MATLAB R2015b below:

Please follow the steps provided below to setup MATLAB Coder for C Code Generation:

• Install a supported C/C++ compiler, as specified in the link above. Please skip this step if you already have a supported compiler installed. For the purpose of this article, we have provided a link to the Windows SDK 7.1 with  .NET framework 4.0 compiler, which is supported for MATLAB R2015b. Please find the link to the installation file below:

          https://www.microsoft.com/en-us/download/details.aspx?id=8279

         NOTE - In case there any issues during the installation process, specifically if you observe an 'Installation Failed' error message, please refer to the following link:

  * Please run the following command at the MATLAB Command Window:

                >> mex -setup

_         This command will locate all the C/C++ Compiler installed on the machine and allow you to set one as the default compiler for code generation. For more information on this command, please refer to the link:

• MATLAB has now been setup for code generation.

With regards to the 2nd question, MATLAB Coder can be used to generate code for multiple entry-point functions. When adding an entry-point function in the MATLAB Coder app, there is an option to add more entry-point functions.
