I actually figured out the problem a while back.I didnt add the setup file to bashrc and so whenever i opened a new terminal , i got this error.Still thanks vmatos.

Thanks Icehawk101.When i deleted the roslib and ran rosrun rosserial_arduino make_libraries.py ~/sketchbook/libraries ,the required header files were generated.

Yeah i tried that too but no result.

I am trying to send a custom message from a ros publisher to an arduino mega using rosserial.The package containing the the publisher and custom message builds fine.I tried to generate headers for the custom message by using the command rosrun rosserial_client make_library.py path_to_libraries message_package given in rosserial_client/tutorials but it failed to generate the required header file for arduino.Can someone help me? The custom message file contains just two int16 variables.

I am explaing what i did and this worked for me.

Follow the procedures given in the tutorial Arduino IDE setup http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup upto the point where you gitclone it from gitclone repository.Then instead of catkin_make type in the following command catkin_make -DCATKIN_WHITELIST_PACKAGES=rosserial followed by catkin_make install-DCATKIN_WHITELIST_PACKAGES=rosserial.Now go to your workspace/src/rosserial where you will find 11 packages including rosserial.Now repeat the last two commands that you typed in for all of these packages like catkin_make -DCATKIN_WHITELIST_PACKAGES=rosserial_arduino and catkin_make install-DCATKIN_WHITELIST_PACKAGES=rosserial_arduino so on till catkin_make install-DCATKIN_WHITELIST_PACKAGES=rosserial_xbee.Now follow the tutorial from the point where you go to arduino sketchbook cd <sketchbook>/librariestill the end.

While trying to run the Hello World tutorial in arduino using rosserial,i always get this error.

    File "/home/renjith/catkin_ws/src/rosserial/rosserial_python/nodes/serial_node.py", line 39, in <module>
    from rosserial_python import SerialClient, RosSerialServer
ImportError: No module named rosserial_python

I am running on ros kinetic and ubuntu 16.04 LTS.

I have tried to install rosserial for kinetic.But when i try to install ros_lib into arduino environment,it gives the error message [rospack] Error: package 'rosserial_arduino' not found .
