Error Message while programming using avrdude and Codeblock

Question

I was setting up codeblock for AVR. I am able to compile and build. But while buring using avrdude, I see lot of stderr messages. Can anyone tell what could be the reason? The program however gets written correctly to the controller.

My post build configuration in code block is avr-objcopy -O ihex -j .text -j .data $(TARGET_OUTPUT_FILE) $(TARGET_OUTPUT_FILE).hex

Below is the Error Details:

Answer 1

You're seeing output in stderr because avrdude outputs to stderr. If you want to suppress non-error output then pass -qq to avrdude.
