CCS/TMS320F28379D: Can't find class symbols

Marcel Kummer

Tool/software: Code Composer Studio

Hello everyone,

I wanted to extend an existing Project by some c++-code.

I made a new .h and .cpp file.

And wrote a little Test-Class to check if the c++ is working properly.

.h file:

#ifndef IE_FIELDBUSPROTOKOLL_H_
#define IE_FIELDBUSPROTOKOLL_H_

#ifdef __cplusplus
extern "C" {
#endif

/*****************************************************************************/
/*! \file IE_FieldbusProtokoll.h
* \brief XXXXXXXX
* \author {Marcel.Kummer}
* \date   {2018}
*****************************************************************************/


/*****************************************************************************/
/*!  \addtogroup FieldbusProtokoll-MotherClass
*    \{                                                                      */
/*****************************************************************************/

class FieldbusProtokoll {
public:
    int a;

private:
    void test();

};

#ifdef __cplusplus
}
#endif// extern "C"

/*****************************************************************************/
/*! \}                                                                       */
/*****************************************************************************/

#endif /* IE_FIELDBUSPROTOKOLL_H_ */

and the .cpp file:

/*****************************************************************************/
/*! \file IE_FieldbusProtokoll.cpp
* \brief XXXXXXXXX
* \author {Marcel.Kummer}
* \date   {2018}
*****************************************************************************/

#include <IE_FieldbusProtokoll.h>

/*****************************************************************************/
/*!  \addtogroup FieldbusProtokoll-Motherclass
*    \{                                                                      */
/*****************************************************************************/

void FieldbusProtokoll::test(){
    this->a = 1;
}

/*****************************************************************************/
/*! \}                                                                       */
/*****************************************************************************/

It's compiling without errors.

But the keywords: class, private, public aren't highlighted in any way.
Also when I use the FieldbusProtokoll-class anywhere in the Projekt CCS can't find the Symbol when pressing F3. ("Selected text cannot be mapped to a symbol name")
The CodeCompletion also isn't working while typing any class-related stuff. ("this." won't expand and suggest me any class members)

Do I have to adjust some settings in the project or what could lead to this behaviour?

Marcel,

Are you using CCSv8.2.0? There is an issue in 8.2 where C++ code is not properly scanned. This issue is reported to be fixed in CCSv8.3.0 which is now available for download. Would you be able to give 8.3 a try to see if it resolves the issue for you?

Regards,
John

Hello John,

yes I am using v8.2, I will update and come back to you later.

Thanks and regards,

Marcel.

The C++ is now working, but with the CCS v8.3 I now get an error I have never seen bevore.

Type Invalid arguments 'Candidates are: void * memcpy(void *, const void *, unsigned long int)'

F2837xD_SysCtrl.c /netX90_getting_started/TMS320F2837xD line 68 Semantic Error

    //
    // Copy time critical code and Flash setup code to RAM. This includes the
    // following functions: InitFlash()
    //
    // The  RamfuncsLoadStart, RamfuncsLoadSize, and RamfuncsRunStart
    // symbols are created by the linker. Refer to the device .cmd file.
    //
    memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);

This was the code in the SysCtrl.c which now causes the error.

It sounds like the Code Analysis (static code checker) tool is running vs a build error.

There are a bunch of rules that you can enable. This is normally off by default. This is what the rules look like. You can get to them from the preferences dialog if you select the option at the bottom to show advanced capabilities.

Then in your project you can configure when it runs:

Is it showing as on for you?

Specifically this would be the rule that is triggering the error:

Thanks, again.

This solved the issue.

But I don't understand why, because I use the project-settings of my project to enable the static codeanalysis and in CCS v.8.2 this error didn't accure.

Thanks and regards,

Marcel.

Marcel,

It is likely a dependency between the C++ indexer and the analysis tool. In 8.2 the indexer was disabled for C++ and would not be giving the info to the analysis tool. That is my best guess.

John
