[ros-users] error of rosmake roscpp on Ubuntu 8.04

Hi all Ros users,

I tried to source-build install with ROS from svn repositories using
rosinstall.
But rosmake roscpp failed, roscore can't be compiled...
Error logs are below:

My system environments are Ubuntu8.04LTS, gcc4.2.4.
Where should I define __LITTLE_ENDIAN ?
How do I resolve this error?

Please give me advice.

Thank you.
