HI @Budhaditya, the issue you are encountering is expected due to the compatibility limitations of MATLAB R2013a and xPC Target. Although the mex -setup command can detect compilers such as those provided by Windows SDK 7.1 and Visual Studio 2010 tools, the xpcsetCC utility requires a full installation of a supported Microsoft C/C++ compiler. The Windows SDK alone does not fulfill these requirements, which is why xpcsetCC -setup does not detect any available compilers on your system.
xPC Target in R2013a officially supports only a limited set of compilers, namely Microsoft Visual C++ 2008 Professional Edition with Service Pack 1 and Microsoft Visual C++ 2010 Professional Edition with Service Pack 1. These compilers must be installed in their 32-bit versions, and only the full Professional editions are supported. Express editions or SDK-only configurations are not compatible with xPC Target because they lack the required linker, libraries, and integration for real-time code generation.
The failure of xpcsetCC -setup to detect your compiler is because it does not recognize SDK-based setups as valid toolchains for xPC. The xPC Target build process relies on specific paths and compiler infrastructure that are only provided with the supported Professional editions. Therefore, even if mex -setup works correctly, xPC will not function without the proper compiler.
To resolve this, you need to install a supported version of Microsoft Visual Studio. Either Visual Studio 2008 Professional Edition with SP1 or Visual Studio 2010 Professional Edition with SP1 should be used. Once installed, you can run xpcsetCC -setup in MATLAB to configure the compiler. After this step, you should be able to compile your model for xPC Target using the slbuild command.
In summary, the only reliable solution is to install one of the officially supported full compilers. Manually setting the compiler path with xpcsetCC('C', ...) and xpcsetCC('CPP', ...) will not succeed unless the compiler itself is fully compatible and recognized by MATLAB's xPC environment. Hope this helps!
