how to use custom c library in stateflow?

I try to access the function in a custom c library but I obtain the error:

"the following functions are undefined in specified custom code source files or library files"

It seems that stateflow sees the header where the function is declered but not the .dll.

in configuration parameters I link the path where the library .lib is and I put the .dll in the same folder of the stateflow model.

What can I do?

Hello Matteo,

I understand you are facing an issue while attempting to access a function in a custom C library from Stateflow, resulting in an error stating that the function is undefined.

To address the issue, I recommend following these steps:

1. Open the Configuration Parameters of your project.
2. Navigate to the Simulation Target section.
3. In the Code Information tab, ensure that you have included the necessary header files by adding them to the 'Include headers' field.
4. Verify that you have correctly specified the folder paths containing the custom header, source, and library files in the 'Include directories' field.
5. Double-check that you have listed all the required source files in the 'Source files' field.
6. Make sure you have accurately entered the names of the necessary libraries in the 'Libraries' field.

Kindly refer to the following MATLAB documentation for further information on how to use custom C library in Stateflow https://www.mathworks.com/help/stateflow/ug/share-data-using-custom-c-code.html

Hope this helps.
