avr-gcc compilation? Can someone help me - c

Question

I have a problem when I compile my code, it shows errors like :
main.c:33:5: warning: 'PORTE_INT0_vect' appears to be a misspelled signal handler
ISR(PORTE_INT0_vect)
^
In file included from main.c:8:0:
main.h:15:19: error: 'PORTE' undeclared (first use in this function)
#define DATA_PORT PORTE``
^
main.c:35:11: note: in expansion of macro 'DATA_PORT'
inbit = DATA_PORT.IN & DATA_PIN;
^
main.h:15:19: note: each undeclared identifier is reported only once for each function it appears in
#define DATA_PORT PORTE

main.c:35:11: note: in expansion of macro 'DATA_PORT'
inbit = DATA_PORT.IN & DATA_PIN;
I write this on terminal :
avr-gcc -g -Os -mmcu=atmega32 -c main.c
Can someone help me please and tell me what is the problem? I am new with aver so I dont understand anything about this errors.
Sorry my english sucks.

Answer 1

The code you are trying to compile was written for an ATxmega128. This is a completely different line of microcontroller from the ATmega32 you're using, and does not have the same peripherals. For instance, the ATmega32 only has GPIO ports PORTA through PORTD, and entirely lacks the programmable multi-level interrupt controller (PMIC).
This code will require significant changes to run on your microcontroller, if it is possible at all. This is probably not a good introductory project for you.
