Data Types

The RXF uses AUTOSAR defined data types, which are defined in WSTCompilerTypes.h which is located in the directory <Rhapsody>\Share\WST_RXF_V5\<your product>\Source and <your path on Linux>/<product>/Source

These types are: sint8, uint8, sint16, uint16, sint32, uint32, float32, float64, uint8_least, uint16_least, uint32_least, sint8_least, sint16_least and sint32_least.

In some cases, one or more of these types are also defined by your toolchain or (third party) include files. To circumvent conflicts, you can disable the type definitions in WSTCompilerTypes.h. We use a test using a constant, for example:

#ifndef AUTOSAR_SINT16_DEFINED
#define AUTOSAR_SINT16_DEFINED
typedef signed short        sint16;         /*      -32768 .. +32767          */
#endif

When you do not want to use such type definition in WSTCompilerTypes.h, you can do this in three ways:

define AUTOSAR_SINT16_DEFINED at the Property CppCompileSwitches using -DAUTOSAR_SINT16_DEFINED which will be inserted in a generated RxfConstants.h
define AUTOSAR_SINT16_DEFINED in the (third party) include file where the same type is defined
define AUTOSAR_SINT16_DEFINED in the file WST.h which is installed in <Rhapsody>\Share\WST_RXF_V5\<your product>\Source and <your path on Linux>/<product>/Source

You can use the following defines to prevent a corresponding type definition:

AUTOSAR_SINT8_DEFINED
AUTOSAR_UINT8_DEFINED
AUTOSAR_SINT16_DEFINED
AUTOSAR_UINT16_DEFINED
AUTOSAR_SINT32_DEFINED
AUTOSAR_UINT32_DEFINED
AUTOSAR_FLOAT32_DEFINED
AUTOSAR_FLOAT64_DEFINED
AUTOSAR_UINT8_LEAST_DEFINED
AUTOSAR_UINT16_LEAST_DEFINED
AUTOSAR_UINT32_LEAST_DEFINED
AUTOSAR_SINT8_LEAST_DEFINED
AUTOSAR_SINT16_LEAST_DEFINED
AUTOSAR_SINT32_LEAST_DEFINED.
