Configuring ROS
If you have not installed ROS, I have written a short guide describing the process. It can be found here found here
The first step is to check whether the environment variables for ROS are setup properly Do a
{% highlight bash %} tasdik@Acer:~$ export | grep ROS {% endhighlight %}
Look for ROS_ROOT and ROS_PACKAGE_PATH whether they are set.
It should look something like this
If not, just do a
{% highlight bash %}
tasdik@Acer:~$ source /opt/ros/
where the distribution name of you OS. version of ROS installed (Jade Turtle for our case).
Creating ROS Workspace
I will be using catkin to create my workspace.
{% highlight bash %}
tasdik@Acer:~$ mkdir -p /catkin_ws/src
tasdik@Acer:$ cd /catkin_ws/src
tasdik@Acer:$ catkin_init_workspace
{% endhighlight %}
Even though the folder is empty(we just have a file named CMakeLists.txt). We can still build the workspace.
{% highlight bash %}
tasdik@Acer:$ catkin_make
tasdik@Acer:$ cd ~/catkin_ws/
{% endhighlight %}
Do an ls and now you can see that we have folders like build, devel folder.
Inside the devel folder, there are several *.sh files
Source the setup file
{% highlight bash %} tasdik@Acer:~/catkin_ws$ source devel/setup.bash {% endhighlight %}
To make sure, everything is done correctly so far, do
{% highlight bash %}
tasdik@Acer:/catkin_ws$ echo $ROS_PACKAGE_PATH
/opt/ros/jade/share:/opt/ros/jade/stacks
tasdik@Acer:/catkin_ws$
{% endhighlight %}
If that is your Output for the prompt, you are good to go.
Till then Goodbye!
