How to Compile C code generated by Embedded Coder to run it in S-Function Simulink

Dear Community,

I have generated the MPC Controller c code to execute it faster in Simulink Real Time. My code is successfully generated but when I used to compile it using mex function I faced an error and I was unable to find its solution.

My purpose in compiling the c file is to put it into S-Function and execute it in real time because s-function executes faster than MPC Controller simulink block.

I used both Simulink Coder and Embedded Coder for generating codes both gave different errors.

First I will show you files generated by Embedded Coder; my block name was "Subsystem", In the below picture left side shows my all files generated, and command windows show the error while compiling the c file.

After facing a problem in Embedded Coder I generated code using Simulink Coder which also gives me errors.

You can use "S-function Target (rtwsfcn.tlc)" for model or subsystem for code generation. You don't need to re-compile the C code generated via Coder products into s-functions. See the documentation below for further information.

Use S-Function Target for Model or Subsystem - MATLAB & Simulink (mathworks.com)

Thanks, you suggested a good method. But another method is that MATLAB provides an option Generate S-Function, I used that and it's work for me.
