Compilation avr sous jaunty

Bonjour,

Bon, ce post sera peut-être un peu hors-sujet mais voilà :

J'essaie de me mettre à le programmation des microcontroleurs avr.  J'ai acheté le livre "C programming for microcontrollers" de Joe Pardue.  site http://www.smileymicros.com

Comme d'habitude, il y en a que pour Windos.  Les exemples compilent sous cet os. 

J'ai essayé sur ma machine qui fonctionne sous Jaunty. 

Mais ! mais !!
Les programmes les plus simples compilent et tout est super. 
Par contre, les programmes un peu plus complexe où il y a une communication sériel par exemple, j'obtiens des erreurs.  

Compiling: PC_Comm.c
avr-gcc -c -mmcu=atmega169 -I. -g -Os -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Wall -Wstrict-prototypes -Wa,-adhlns=PC_Comm.lst  -std=gnu99 -Wp,-M,-MP,-MT,PC_Comm.o,-MF,.dep/PC_Comm.o.d PC_Comm.c -o PC_Comm.o 
PC_Comm.c: In function ‘isCharAvailable’:
PC_Comm.c:49: error: ‘UCSR0A’ undeclared (first use in this function)
PC_Comm.c:49: error: (Each undeclared identifier is reported only once
PC_Comm.c:49: error: for each function it appears in.)
PC_Comm.c: In function ‘receiveChar’:
PC_Comm.c:56: error: ‘UDR0’ undeclared (first use in this function)
PC_Comm.c: In function ‘sendChar’:
PC_Comm.c:64: error: ‘UDR0’ undeclared (first use in this function)
PC_Comm.c:70: error: ‘UCSR0A’ undeclared (first use in this function)

Je comprends qu'il y  a un problème de déclaration de ces variables. 

J'ai repéré dans le makefile, ces lignes qui pourraient en être la cause.  

-----------------------------------------------------------------------



# Define directories, if needed.

DIRAVR = c:/winavr

DIRAVRBIN = $(DIRAVR)/bin

DIRAVRUTILS = $(DIRAVR)/utils/bin

DIRINC = .

DIRLIB = $(DIRAVR)/avr/lib

que j'ai modifié en 

# ---------------------------------------------------------------------------



# Define directories, if needed.

DIRAVR = /usr/lib/avr/
DIRAVRBIN = $(DIRAVR)/bin

DIRAVRUTILS = $(DIRAVR)/bin
DIRINC = $(DIRAVR)/include
DIRLIB = $(DIRAVR)/lib

Je reste bloqué.  Quelqu'un a -t-il une expérience dans la compilation croisée et les fichiers make pour venir à mon secours ?

Je joints ci-dessous tout le fichier make pour info .

Merci

Re : Compilation avr sous jaunty

Comment as tu installé l'environnement de développement AVR sous ubuntu ?
Pour linux faut récupérer la librairie avr-libc et la compiler (http://mirrors.linhub.com/savannah/avr-libc/).
UCSR0A et les autres sont des #define dans les fichiers avr/ioxxx.h  (xxx = m165p ... etc).

Re : Compilation avr sous jaunty

J'ai installé l'environnement via

sudo aptitude install gcc-avr avr-libc gdb-avr avrdude

J'ai suivi ce site http://www.robotique-ludique.fr/index.p … sous-Linux

Comme j'utilise le butterfly qui a un Atmega169.  Je pensais que ça aurait fonctionné.

Re : Compilation avr sous jaunty

Regarde ce que donne un

Peut être un problème de version de librairie ?

Merci malgré tout de votre aide. 
Je continue de chercher et peut-être essayer en compilant l'avr-libc.
