Hello,

I need to get run a C sfunction some libraries like stdio.h and stdlib.h.

I tried to copy that libraries in the current path. But that libraries call other libraries and I get errors compilling (mex) the C sfunction.

How can I include all libraries which i need? I am a Beginner Thanks a lot

Hi Mario,

The easiest way to include custom libraries in C S-Functions is to use the S-Function Builder block, which is located in the Library Browser under Simulink>User-Defined Functions. On the Libraries tab of the S-Function Builder UI, you can specify the custom headers and library files to include.

Hi Mario,

You shouldn't need to copy all of the system library headers like stdio.h to the local directory. I recommend using the angle brackets, < and >, to specify system library headers. You can use

#include <stdio.h>

in the "Includes" section, which will search the standard system header locations. If it is a custom library header, you can store it in the current directory and use quotes instead:

#include "myHeader.h"

For custom library files, you can specify the location to the files in the "Library/Object/Source Files" section.
