Hello,
I have created a simulink model which implements an inlined s-function which uses a .tlc file and external .c and.h files. I have configured everything correctly as the simulation is working, and when I perform a compile this also goes without issues.
However, when a try to save te model as a protected model the compilation fails as it cannot fild the external .c and .h files. Event hough i have configured it correctly under "custom code" in the model settings.
I would expect that saving it as a protected model would also use these settings, but it does not seem to be the case. What am i dowing wrong?

Where do I set the compiled code options? Do wou mean setting content type to binaries as in the screenshot below?
I already have done this without succes.

Even I am not able to find this option. I shared the documentaiton hoping it might be there but I just checked its not. Not sure how to go about this then.

Hello Robrecht,
I have a created an example model that implements a wrapper inlined S-Function as described in the documentation below:
https://www.mathworks.com/help/rtw/tlc/inlining-s-functions.html?searchHighlight=LibAddToModelSources&s_tid=srchtitle_support_results_1_inline%20S-function#f34660
By using the “LibAddToModelSources” function in the TLC file directly, I was able to successfully compile and build the model without adding the sources to the “Custom Code” section in the Configuration Parameters. For more information refer to the function documentation for “LibAddToModelSources” here:
https://www.mathworks.com/help/rtw/tlc/code-configuration-functions.html#bp6sft1
Additionally, the following documentation describes the limitations of specifying complete source file path for your C code:
https://www.mathworks.com/help/rtw/ug/build-integrated-code-within-the-simulink-environment.html#bp67s_y-4
I was able to generate the Protected Model, and successful extract the contents of “model1_protected.mlproj” and use the Protected Model. I used MATLAB R2024b to create the model and I am attaching the zip file here.The above workflows assumes that you are using wrapper inline S-Functions and I hope this helps resolves your issue.
