Hello I have my Simulink model which compiles perfectly with SLRT for speedgoat machine. Now when I try to add an S-function block (developed by a third party using Simulink Coder), the build returns: “The make command returned an error of 2”. Is this approach compatible with SLRT? Do I have to configure it in a particular way to make it work? Thanks.

This error may be related to an unsupported release to compiler combination. Please verify https://www.mathworks.com/support/requirements/previous-releases.html for the release your are using.

The sfunc was compiled with Matlab 2015b using Microsoft Windows SDK 7.1 (C) while I’m using Matlab 2023a (without any compiler), is it compatible? It’s not clear to me from the link above.

In case you plan to run a Simulink simulation with R2023a and inlude a C-MEX S-Function from a project partner, please make sure the S-Function was created by the project partner using R2023a. In case you have the source code, you can create the S-Function yourself.

In your intial question, you mention a Simulink Real-Time application. Thus, there might be a different problem, but to isolate it, I still recommend using an S-Function created in the same release you are using.
