How to resolve S-function mdlRTW error during code generation?

I'm trying to use a C MEX S-function in my Simulink model. I can run the model in normal mode, but I'd like to use it in Rapid Accelerator mode. The following error occurs when I try to build the rapid accelerator target:

This S-function block must have a corresponding TLC file since it has an mdlRTW() function

Why does this error occur? I have only non-tunable parameters in my S-function so I left the MDL_RTW function empty (at the end of the S-function). Where do I have to begin to resolve this question? I'm pretty new to code generation of S-functions so I have no idea where to start.

I can include my S-function if necessary.

I though I needed to mdlRTW function to produce code for the rapid accelerator. However, this is not necessary. Simply deleting this part of the S-function solved the problem

如果我想生成代码，就必须需要一个TLC文件

if I want to generate the code, so I must to a TLC file,

这个TLC文件是自动生成的， 还是新建一个文件，更改后缀生成的呢？ 因为复制别人的TLC，但是不能正常使用，

Is this a newly created file or an automatically generated one? Because it copies other people's TLC, but it can't be used normally,
