You probably need to run:

source /opt/ros/hydro/setup.bash

Or add it to your ~/.bashrc

It also matter where this is added in .bashrc (I've done some trial and error.. but can't quite say yet if I know why it worked and why it didn't)

You can configure your PATH (and the whole ROS environment) "manually". Try adding these lines to the end of your ~/.bashrc

source /opt/ros/hydro/setup.bash

export ROS_MASTER_URI=http://localhost:11311

export ROS_PACKAGE_PATH=/opt/ros/hydro/stacks:/opt/ros/hydro/share:/path/to/my/workspace

export EDITOR='gedit'

ROS_HOSTNAME=localhost is almost certainly wrong and will in the best case (on a local machine) do nothing. The other ROS variables should have been set by sourcing setup.bash. You don't need to repeat those unless you really know what you're doing.

You are right: http://wiki.ros.org/ROS/EnvironmentVariables#ROS_IP.2BAC8-ROS_HOSTNAME I gave a useless example (I edited my answer)

I would absolutely NOT try to set up your environment manually. Among other things, you're failing to set up CMAKE_PACKAGE_PATH and LD_LIBRARY_PATH, and you're neglecting all of the rosbash extensions and any other setup steps that are added by installed packages.

That's why, I put this first line if you look with more attention at my answer: source /opt/ros/hydro/setup.bash
