TouchGFX error: no declaration matches ERROR

[TahaBugraa]

Hello there, I was working on TouchGFX and when i tried to build my code i got 

error: no declaration matches 'bool TouchGFXHAL::blockCopy(void*, const void*, uint32_t) and same for endFrame and beginFrame. 

But i couldn't solve the problem. 

Here is the part from TouchGFXHAL.cpp file.

bool TouchGFXHAL::blockCopy(void* RESTRICT dest, const void* RESTRICT src, uint32_t numBytes)
{
return TouchGFXGeneratedHAL::blockCopy(dest, src, numBytes);
}

/**
* Configures the interrupts relevant for TouchGFX. This primarily entails setting
* the interrupt priorities for the DMA and LCD interrupts.
*/
void TouchGFXHAL::configureInterrupts()
{
// Calling parent implementation of configureInterrupts().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.

TouchGFXGeneratedHAL::configureInterrupts();
}

/**
* Used for enabling interrupts set in configureInterrupts()
*/
void TouchGFXHAL::enableInterrupts()
{
// Calling parent implementation of enableInterrupts().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.

TouchGFXGeneratedHAL::enableInterrupts();
}

/**
* Used for disabling interrupts set in configureInterrupts()
*/
void TouchGFXHAL::disableInterrupts()
{
// Calling parent implementation of disableInterrupts().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.

TouchGFXGeneratedHAL::disableInterrupts();
}

/**
* Configure the LCD controller to fire interrupts at VSYNC. Called automatically
* once TouchGFX initialization has completed.
*/
void TouchGFXHAL::enableLCDControllerInterrupt()
{
// Calling parent implementation of enableLCDControllerInterrupt().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.

TouchGFXGeneratedHAL::enableLCDControllerInterrupt();
}

bool TouchGFXHAL::beginFrame()
{
return TouchGFXGeneratedHAL::beginFrame();
}

void TouchGFXHAL::endFrame()
{
TouchGFXGeneratedHAL::endFrame();
}

================================================
and this is part from TouchGFXHAL.hpp file.

virtual bool beginFrame();

virtual void endFrame();

/**

*
* @brief This function is called whenever the framework has performed a complete draw.

*/
virtual void flushFrameBuffer()
{
TouchGFXGeneratedHAL::flushFrameBuffer();
}

And the exactly error codes is here:

Hello @TahaBugraa ,
These functions that you are talking about are generated by TouchGFX, and you can customize them if you prefer. But apparently, the compiler was not able to chain the functions together. 
Have you tried regenerating code from the designer and then compile again?

[TahaBugraa]

Yes, i tried 3 times in TouchGFx and many times in CubeIDE(clean project then build again). Nothing changed.
