Hi,
I am generating code from a Simulink model using embedded coder support package for STM32 processors. The generated code contains a dependency on mw_stm32_utils.h, but this file does not exist in the generated output. Because of that I can't build the project.
The dependency appears in the generated model.h header file:
#include "mw_stm32_utils.h"
The only files generated were model.h, model.c and rtwtypes.h. So my question is were does this dependency come from?
I attached the generated source files to this post.
Thanks you.

Try using packNGo to package all code to relocate it to a different environment:

Unfortunately, the dependency persists even when using packNGo or the 'Package code and artifacts' option. I tested this with different compilers and both C and C++, but the issue remains.

I found this header file here:
C:\ProgramData\MATLAB\SupportPackages\R2025a\toolbox\shared\supportpackages\stm32\include
add this directory to the include path should work.
