Matlab Autosar Code Genration Error

When Generating Code with Autosar,

I have these problems.

Parsing Output Code in C Function block failed with the messages:

In line 1000014:error: 20, identifier "uint8" is undefined

In line 1000014:error: 20, identifier "sint16" is undefined

and so on,,

This problem occur in C Function Block.

When I using int32, uint16.. Type, they already defined in C Function Block.

Should I defined one more? And Where shoude I define it?

I write down code in OutputCode Only

Hi @dayoung,

If possible could you provide the required files, so that I can have a look into it? meanwhile try changing the code to use and define autosar types instead or a workaround could be to replace the "C Function" block with the "C Caller" block.

Hi @dayoung,

This seems to be a bug and a possible workaround to solve this is to specify the following type definitions in Simulation target custom code. This should resolve undefined type identifier issue without introducing any modifications to the generated AUTOSAR code.

#ifndef RTWTYPES_H
#define RTWTYPES_H
#include "tmwtypes.h"
#endif

typedef real_T float64;
typedef real32_T float32;
typedef int32_T sint32;
typedef int16_T sint16;
typedef int8_T sint8;
typedef uint32_T uint32;
typedef uint16_T uint16;
typedef uint8_T uint8;
typedef boolean_T boolean;
typedef uint64_T uint64;
typedef int64_T sint64; 

Simulation Target custom code should be included in the include header section of simulation target of model configuration parameters:

I hope this helps.

Thank you This really help for me
