Hello.
I'm using Code::Blocks 13.12 rev 9501
SDK Version 1.19.0
I've downloaded it from
http://sourceforge.net/projects/arduinodev/files/CodeBlocks-Arduino-20140626.7z
I know I need ask this question on
http://arduinodev.com/forums/ but I'll try do it here.
I need fix one .h file from library LowPower
https://github.com/LowPowerLab/LowPowerI need change these strings in header file:
void powerDown(period_t period, adc_t adc, bod_t bod);
void powerSave(period_t period, adc_t adc, bod_t bod, timer2_t timer2);
void powerStandby(period_t period, adc_t adc, bod_t bod);
void powerExtStandby(period_t period, adc_t adc, bod_t bod, timer2_t timer2);
to this
void powerDown(period_t period, adc_t adc, bod_t bod) __attribute__((optimize("-O1")));
void powerSave(period_t period, adc_t adc, bod_t bod, timer2_t timer2) __attribute__((optimize("-O1")));
void powerStandby(period_t period, adc_t adc, bod_t bod) __attribute__((optimize("-O1")));
void powerExtStandby(period_t period, adc_t adc, bod_t bod, timer2_t timer2) __attribute__((optimize("-O1")));
it will fix Sleep power consumption in arduino.
but I receive this output after compiling:

AVR Memory Usage
----------------
Device: atmega328p
Program: 14018 bytes (42.8% Full)
(.text + .data + .bootloader)
Data: 1633 bytes (79.7% Full)
(.data + .bss + .noinit)
Process terminated with status 0 (0 minute(s), 0 second(s))
0 error(s), 4 warning(s) (0 minute(s), 0 second(s))
So I need somehow enable the optimize attribute in this build tool
Any advice how to do it?
Thanks!
