Programming on Eclipse

Hi There

recently I trying to establish the developin environment on eclipse

according to the link as below, I just need to follow the steps.

when I were trying to configure the

Project-> Properties -> C/C++ Build -> Settings -> AVR C/C++ Linker

I can not find the configuration option under setting, but I can find it in the Tool chan editor.

Does any one know how to make the Avr C/C++ Linker configurable???

Thank you so much
