Answer 1

The ros_lib should be installed in your Arduino "sketchbook/libraries". You will have to make the libraries folder and the sketchbook should automatically be generated in the home directory after the Arduino IDE is opened once. Using this command mkdir -p ~/sketchbook/libraries and then cd ~/sketchbook/libraries to should get you into the right folder. To install the ros_lib in the sketchbook use rosrun rosserial_arduino make_libraries.py . As davinci said this is in the setup.

Try installing rosserial from source.

Answer 2

Did you follow all the steps in the setup? And copied the libraries? Seems that it can't find your libraries.

suppose that the opt/ros/electric/stacks/rosserial/rosserial_arduino/libraries/ros_lib it's copied on the sketchbook folder
