I inquire about TouchGFX Compile error.

[mSH.1]

hello

​

I inquire about TouchGFX Compile error.

​

To call a specific function by including discovery.h in Model.cpp

A compile error occurs.

​

However, in CubeIDE, it compiles normally and runs well.​

​

I want to know why a compile error occurs in TouchGFX and a normal compile in CubeIDE.

​

1.The development environment is as follows

​

• STM32H725g-dk
• CubleIDE 1.9.0
• TouchGFX 4.19.1​

​

​

​2. The source of model.cpp is as follows.

===================================================================

​

#ifndef SIMULATOR

extern "C" {

#include "stm32H7xx.h"

#include "stm32h735g_discovery.h"

}

#endif

​

​

void Model::tick()

{

#ifndef SIMULATOR

​

  int button_sample = BSP_PB_GetState(BUTTONn); //BUTTONn // BUTTON_USER

  if (button_sample != 0x000F)

  {

    if( buttonState != button_sample )

    {

    modelListener->PUI_data(button_sample);

    buttonState = button_sample;

    }

  }

  else

  {

  buttonState = button_sample;

  }

}

​===================================================================

​

​

3.The error message in TouchGFX is as follows.

[MM..1]

TouchGFX use different makefile as CUBE. You need add search path to added headers and add source files into TGFX makefile.

[Andrew Neil]

@MM..1​  but the posted error is not about problems finding a header file?

[mSH.1]

​

thank you for your reply.

​

I don't know how to modify the makefile in TouchGFX.

Are there any guides provided?

​

@mSH.1​ "To call a specific function by including discovery.h in Model.cpp A compile error occurs. However, in CubeIDE, it compiles normally and runs well.​"

So the TouchGFX build is C++ - is the CubeIDE build also C++, or just plain C ?

This doesn't look right:

#ifndef SIMULATOR
extern "C" {
#include "stm32H7xx.h"
#include "stm32h735g_discovery.h"
}
#endif

Did you mean:

#ifdef __cplusplus
extern "C"
{
#endif
 
#include "stm32H7xx.h"
#include "stm32h735g_discovery.h"
 
#ifdef __cplusplus
}
#endif

@mSH.1

[mSH.1]

hello ​@Andrew Neil​ 

​

Thanks for the useful feature.

​

As I was informed, the moel.cpp part was modified as follows.​

#ifdef __cplusplus
extern "C"
{
#endif
 
#include "stm32H7xx.h"
#include "stm32h735g_discovery.h"
 
#ifdef __cplusplus
}
#endif

​

But the same error occurs.

​It occurs only in touchGFX and compiles normally in CubeIDE.

​

​The error message in TouchGFX is as follows.

@mSH.1​ "As I was informed, the moel.cpp part was modified as follows"

I don't know the context of that snippet, so don't know if it's actually what you wanted - but certainly the original didn't look right.

There may be other places in your code with similar issues?

Do you understand the issues of mixing C and C++, and why/when the extern "C" is required?

You are now getting errors due to not finding header files - so, as @MM..1​  said, you do need to adjust your include paths...
