Hi.
I would like to use C++ in Atmel Studio, so I write code below:
//******Main.CPP*******
#define F_CPU 32000000UL
#include "Settings.h"
#include "ILI9225G.h"
int main(void)
{
Settings st;
st.Config32MHzClock();
InitLCDPins();
while(1)
{
}
}
//******Settings.h********
#ifndef __SETTINGS_H__
#define __SETTINGS_H__
class Settings
{
//variables
public:
protected:
private:
//functions
public:
Settings();
~Settings();
void Config32MHzClock();
protected:
private:
Settings( const Settings &c );
Settings& operator=( const Settings &c );
}; //Settings
#endif //__SETTINGS_H__
//***** Settings.cpp******
#include "avr_compiler.h"
#include "Settings.h"
// default constructor
Settings::Settings()
{
} //Settings
// default destructor
Settings::~Settings()
{
} //~Settings
void Settings::Config32MHzClock()
{
CCP = CCP_IOREG_gc; //Security Signature to modify clock
// initialize clock source to be 32MHz internal oscillator (no PLL)
OSC.CTRL = OSC_RC32MEN_bm; // enable internal 32MHz oscillator
while(!(OSC.STATUS & OSC_RC32MRDY_bm)); // wait for oscillator ready
CCP = CCP_IOREG_gc; //Security Signature to modify clock
CLK.CTRL = CLK_SCLKSEL_RC32M_gc; //select sysclock 32MHz osc
}

* as construct a unique function name for the ISR.

Atmel Studio show this error:
"Error 1 multiple definition of `saved_sreg' "
which saved_sreg is used in avr_compiler.h
could you please guide me how can I fix this error?
