If I don't want simulink to generate the file "rtwtypes.h", how can I do?

I want use Simulink to generate my control function，but It always to generate at least file: "model.c","model.h" and "rtwtypes.h"；

and the"rtwtypes.h" file looks like that , If I Only want generate two file " model.c" and "model.h "， How can I do？ thanks.

   58   typedef int int8_T;
   59   typedef unsigned int uint8_T;
   60   typedef int int16_T;
   61   typedef unsigned int uint16_T;
   62   typedef long int32_T;
   63   typedef unsigned long uint32_T;
   64   typedef float real32_T;
   65   typedef double real64_T;

I don't think you can avoid rtwtypes.h from getting generated because it contains typedefs for platform-independent types. You might be able to do some post-processing on the generated code to replace all platform-independent types like int8_T with the corresponding built-in types for your platform, and discard rtwtypes.h altogether.

Hi Kaustubha,

What's the process of generating rtwtypes.h? Can we modify the process?

I've found that if I choose grt.tlc to generate code, the resulting rtwtypes.h actually includes many other system header files, which means when I deliver the generated code to other people, I have to copy these system header files too. If I choose ert_shrlib.tlc, the resulting rtwtypes.h is actually a complete header file (no hierarchy to other system header files) that I think it integrates all related contents of the system header files together.

Hi Kausthubha,

Instead of rtwtypes.h file can i #include my user defined file in which i gave typedef for all datatypes. I want my user defined file to be #included in my model.h file so what settings should i do for that.
