I am trying to auto launch a roslaunch file, whenever ubuntu starts. I have written a shell command file "start.sh" and it contains "roslaunch pkg_name file.launch" When i try to execute this shell file in terminal, it runs successfully. But when it runs automatically on start up, the terminal shows "source not found", "roslaunch not found" . Can any one help me correct it. the link to autostarting a sh file is : http://ros-users.122217.n3.nabble.com...

i found the problem. The sh file has to be run as a bash file. so by replacing first line (#! /bin/sh) by #! /bin/bash,

Hi guys. I am new to ROS. I wan to run following on the system start up:

1. Roscore
2. ROS Package
3. ROS bag record.

Although i have searched on google and many people have answered this already, but i couldnt understand it, so if any one could help me in a kindergarten teacher way.. Also any suggestion for a good book/blog etc related to linux and ROS, for dummies and new comers like me... Your help would be really appreciated.

Thanks for helping :). But my question is that, can i run two different packages at the same time in ROS.?? The Package1 has a subscriber node which is subscribing to a topic initiated by a publisher of Package2....? If yes What should i do perform communication between two packages at same time..?

Hi every one, I am new to ROS and Masters student. We have two packages in the same work space. I want to use a subscriber node in Package1 to a subscribe to a topic published by a node in Package2. Actually we are doing work on DJI done. DJI has provided their SDK. We want to simulate our algorithms on Matlab and create a package for our algorithm using matlab coder. Then we want to combine matlab coder generated nodes with the nodes provided by DJI SDK. Is it possible.? We are considering matlab algorithm as Package1 and DJI SDK as Package 2. So matlab package node would subscribe to DJI SDK nodes to get data and process this data. So is it possible..?

Hi. Thanks for the reply. I found the error. There was problem with the other packages in the same workspace. One of the other package had wrong cmakelist.txt file..

Thanks :)

Hi... I am to ROS and i would be posting lots of questions. :) Th thing i am trying to do is that i want to create multiple packages inside single catkin workspace. I created my package "my_first_pkg" inside "catkin_ws/src". It worked fine. Then i tried to add another package in the same "catkin_ws/src" with the name "my_second_pkg" using "catkin_create_pkg". Then i run following command

catkin_make

it gives me following error. Invoking "make cmake_check_build_system" failed
