Package autocompletion not working

edit

Hello everyone,

I am using a minimum set of ROS on an embedded system, with also a minimum set of the setup.sh being executed, concretely:

export ROS_DISTRO=indigo
export ROS_ROOT=/opt/ros/$ROS_DISTRO
export ROS_MASTER_URI=http://localhost:11311 
export PATH=$PATH:$ROS_ROOT/bin 
export LD_LIBRARY_PATH=$ROS_ROOT/lib 
export PYTHONPATH=$ROS_ROOT/lib/python2.7/site-packages
export CMAKE_PREFIX_PATH=$ROS_ROOT

I have it running properly. I have installed rosbash and tab completion works ok, although I have to manually source the setup file from rosbash package, following this post . However, roslaunch completion is not working.

What could I be missing?
