How to set interrupt via XC8 for Atmega?

Make sure that you are building with CCI enabled. Use either the command line option -mext=cci, or in the MPLAB X IDE, go to your properties > XC8 Compiler > Preprocessing and Messaging > Use CCI syntax.
 
It looks like the interrupt section in the user's guide was the only one to omit the requirement for this option if you want to use the new syntax. I'll make a note to correct that.

Hi I am using MP LAB IDE V5.30 AND XC8 V2.10
I am trying to write an interrupt  service routine but it is giving me errors
this one :  Interrupt.c:13:7: error: variable has incomplete type 'void'
 
please assist me 
here is my code 
 
void  interrupt   my_isr ()
{
    if (INTCONbits.INT0IE==1)// if (INT0IE=1) to check if the PIR IS PRESSED FOR INTERRUPTION
    {
        for (int flahD2=0;flahD2 <5;flahD2++) // THE LED WILL FLAH 5 TIMES
        {
            LATBbits.LATB5=1;
       for (int count =0;count<20;count++)__delay_ms(13);// delay for 330ms
        LATBbits.LATB5=0;
       for (int count=0;count <20;count++)__delay_ms(13);// delay for 330ms
        }
     
    }
    INTCONbits.INT0IF  =0;// clear the interrupt
   
}
