ubuntu 에서 AVR 컴파일하기

이러다가 조만간.. 메인 컴터를 리눅이로 갈아 탈듯 -_-

(게임도 안하는데 머...)

$ sudo apt-get install gcc-avr avr-libc avrdude

c++ 예제.파일 갯수가 여러개이니 왜 DDRA나 이런게 없냐고 하지 말자?

project & makefile

$ avr-c++ -mmcu=atmega128 IOPort.cpp

avr-gcc 기본 헤더 경로 확인

pi@raspberrypi ~/src/avr $ avr-gcc -print-file-name=include /usr/lib/gcc/avr/4.7.2/include

[링크 : http://ubuntuforums.org/showthread.php?t=1014673]

위의 예제는 직접 DDRA나 PORTA 등을 선언해서 쓴것이고

원래는 아래 경로의 io.h 를 끌어오면 알아서 mmcu에 맞춰서 하위 헤더를 끌어오게 된다.

pi@raspberrypi ~/src/avr $ sudo find / -name io.h /usr/lib/avr/include/avr/io.h

빌드는 성공! 굽는건 나중에
