Why can't I build model in Simulink which contains a S-function?

I'm learning the S-function with the examples in the Matlab, but I failed to build model of the examples. What is confused is that I could run the examples and went through the simulation when the building is blocked.I'm wondering why I can run the S-function but came across various errors, such as the lack of tlc files, the inappropriate configuration of the solver type, when I tried to build model. Many thanks!

• In order to generate code for the s-function, you must place the tlc file in the same folder of S-function. TLC means Target Language Compiler, Which is used to customize the code building process.
• You opt S-function because none of Simulink library blocks Can perform what you really want to do, So you customized a Simulink Block according your requirment. In the same you need to guide MATLAB Coder With Customized building process to generate code for your Customized block.

• Thanks a lot for your explanation of TLC.I have copied a TLC file of a similar example and pasted it over to the same folder as Rule1 said but it didn't work.
• I'm confused about ""guide MATLAB Coder with customized building process". Would you like to explain or show how to achieve it? Since English is my second language, I'm afraid that I failed to understand it literally. I appreciate your answer.
