Fw: [avr-gcc-list] sleep mode error on SM bit

[Ezio Balbo]

Hi Eric,

Thanks to your help,

This is the copiler output from the linux pc:

/*
avr-g++ -g -Wall -fno-exceptions -Os -mmcu=at90s8515    -c -o main.o main.c
main.c: In function `void shutdown()':
main.c:323: error: `SM0' undeclared (first use this function)
main.c:323: error: (Each undeclared identifier is reported only once for
each
   function it appears in.)
main.c:323: error: `SM1' undeclared (first use this function)
main.c:323: error: `SM2' undeclared (first use this function)
main.c:323: error: parse error before `;' token
main.c:324: error: parse error before `)' token
main.c: At global scope:

make: *** [main.o] Error 1
make: Target `all' not remade because of errors.

Compilation exited abnormally with code 2 at Tue Jun 24 23:51:50
*/

and this is the compiler output from the win pc:

/*
avr-g++ -g -Wall -fno-exceptions -Os -mmcu=at90s8515    -c -o main.o main.c
avr-g++ -g -Wall -fno-exceptions -Os -mmcu=at90s8515  -Wl,-Map,main.map -o

main_eeprom.bin
avr-objcopy -j .eeprom --change-section-lma .eeprom=0 -O srec main.elf
main_eeprom.srec

> Process Exit Code: 0
*/

My function shutdown():

void shutdown(void)
{
   VDD_off(); // switch off only the RF device
   io_close(); // configure pin I/O for power down
   enable_external_int (0x80); // enable start switch
   set_sleep_mode(SLEEP_MODE_PWR_DOWN);
   sleep_mode();
}

in the /usr/avr/include/avr directory
the file sleep.h is not the lastest cvs, but v1.5
/*$Id: sleep.h,v 1.5 2003/01/21 06:16:56 troth Exp $*/

In the WinAVR-20030424 istallation package the  header file is version v1.6
/* $Id: sleep.h,v 1.6 2003/04/07 21:55:17 troth Exp $ */

Thanks

Ezio
