How to generate S-Function using legacy tool box for a Function having multiple function calls in it

I am working on S-Function and I am still a beginner.

For a simple adder function I was able to generate S-function block and simulate it using Legacy tool box.

But When i started working on complex function , like a function having call to another function I started facing problems/errors when I compiled the c functions, like :

" c:\users\xyz\appdata\local\temp\mex_zg~1\function_name.obj .text: undefined reference to '_Function_call_1' "

where function_name is file name Function_call_1 : is a called function

and similar error was for all the function calls present inside the function.

Can you please guide me , where I am going wrong ? Is there any reference for these types of code , on how to generate S-Function ?

Did you include the source/library file that contains the definition to '_Function_call_1' in the 'SourceFiles' or 'HostLibFiles' fields of the legacy code tool data structure?
