Making a BWI Workspace
Create your user-side rosdep cache:
rosdep update
We'll setup a catkin workspace for you to work with your code, and link it to the ROS Indigo installation. First, you'll have to figure out if an existing workspace is present. You can check with the following command:
test -d ~/catkin_ws/src && echo "Catkin workspace present"
Browse through the current workspace to see what packages are in the workspace. Some of these packages may be ones you are working on, and some of them may have been downloaded while running these install instructions previously. You'll have to remove packages that were downloaded through these install instructions. If you are unsure, ask for help!
To remove a package, run the following command. This step is not reversible. Do not remove any code that you have not uploaded to github..
cd ~/catkin_ws/src
wstool rm <pkg-name>
rm -rf <pkg-name>
Remove all unnecessary packages.
If you don't have an existing catkin workspace, setup a catkin workspace at ~/catkin_ws:
cd
mkdir -p catkin_ws/src
cd catkin_ws`
source /opt/ros/indigo/setup.bash`
catkin config --space-suffix _cb --init
cd src
wstool init
Setup your environment. You might want to open ~/.bashrc in a text editor to ensure you don't have multiple copies of these lines:
echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
RESTART your terminal
Now your workspace is ready to be used. Since our code is installed from system binaries, it is already available. To understand environment setup in more details, check out the tutorial on the ROS wiki. You should now proceed to the Navigation Tutorial.
Download the appropriate manifest from the BWI repo, rename it .rosinstall and move it into the src directory of your catkin workspace. Then run:
wstool update
If you are using a laptop with an Optimus enabled Nvidia graphics card, you will have to install the bumblebee driver and run the following addtional command:
echo "export OPTIRUN_LAUNCH_PREFIX=optirun" >> ~/.bashrc
