rosws and package indexing
Background: I am a user upgrade ros from electric to fuerte. In electric, I edit .bashrc and setup.* myself. In fuerte, I tried to get familiar with rosws to manage the workspace.
Problem: I have installed openni_camera and openni_launch, using the command
sudo apt-get install ros-fuerte-openni-camera
sudo apt-get install ros-fuerte-openni-launch
So the two packages were installed into opt/ros/fuerte/stacks, which is one of the workspaces.
I can access the folder and run rosmake. However, roscd, roslaunch rosrun cannot find the package openni_camera or openni_launch.
After a while, (I did not source any setup.sh or .bashrc file), roscd can find the package... May I know how can I manually add the two packages into the index.
I have another question. When I create a sandbox, if I directly copy a package into the sandbox, it will be automatically indexed and roscd can access the package. But if I copy the package into /fuerte_workspace, it cannot be indexed. I need to rosws set the folder as an workspace. But fuerte_workspace is already a workspace, so I am setting a workspace inside another one? And packages inside the sub-workspace can be automatically indexed also.
Though most of the time I do not have problems with rosws and the indexing, still want to have somebody can explain this to me in detail. Thx.
