MATLAB: Do I get a compiler error C4235 complaining about the _asm keyword when building a Simulink Real-Time model in MATLAB R2014a

compilererrorreal timesimulinkxpc

I am trying to build a Simulink model for a Simulink Real-Time target in MATLAB R2014a but the build fails with the following error.

"error C4235: nonstandard extension used : '_asm' keyword not supported on this architecture"

I have "mex -setup" set to Visual Studio 2013 and have not had any issues with building non-Simulink Real-Time models before. What is going on?

Microsoft Visual C++ Professional does not support all features of Stateflow and Simulink Real-Time. Refer to the following link for a list of supported compilers for MATLAB R2014a and check the column labeled "Simulink Real-Time".

Simulink Real-Time R2016a does detect the Visual Studio 2015 compiler, but does not support it. You need to choose a different compiler. If you have other supported C/C++ compilers installed, you can use "slrtsetCC" to choose the one that should be used with Simulink Real-Time. For instance if you have Visual Studio 2013 installed in the default location: "C:\Program Files (x86)\Microsoft Visual Studio 12.0", you can use:

slrtsetCC('VisualC', 'C:\Program Files (x86)\Microsoft Visual Studio 12.0')

The list of supported compilers can be found at the following link:

Hi Zi,

Yes, Real-Time Windows Target is now called Simulink Desktop Real-Time. It looks like the change happed in R2015a.
