HELP: Couldn't find package libboost1.35-dev, libboost-system1.35-dev

[Junjie QIAN <qjj1983@gmail.com>]

Hi all,

I am a new user of Debian OS, and I am running a simulator on Debian 5.0.8-amd64 OS.
The problem I encounter is that when I execute "apt-get install  libboost1.35-dev libboost-system1.35-dev" , and the result shows that "Couldn't find package libboost1.35-dev, libboost-system1.35-dev".

I have tried add some new address to /etc/apt/sources/list. (deb http://http.us.debian.org/debian stable main contrib non-free
     deb http://non-us.debian.org/debian-non-US stable/non-US main contrib non-free
     deb http://security.debian.org stable/updates main contrib non-free
     
     # Uncomment if you want the apt-get source function to work
     #deb-src http://http.us.debian.org/debian stable main contrib non-free
     #deb-src http://non-us.debian.org/debian-non-US stable/non-US main contrib non-free). But it doesnot work.

Any idea about this?
Thanks!
Best
