Problem with fuerte version of ROS...
Hello guys, i'm just starting to learn ROS, but i'm having some problems following the tutorials: 1- The Turtlesim windows was supposed to show a turtle, but mine just shows the blue color. What did i do wrong? Or is it because i'm using the beta version of ROS (fuerte)?
2- The command "rosmsg show <msg name="">" doesn't work! every time i try it, it shows me: "Cannot locate message [Num] in package [beginner_tutorials] with paths [/home/beto/ros_workspace/beginner_tutorials/msg]", but in this folder there is the msg Num.msg, what am I doing wrong?
3- The command "roswtf" tells me: "ROS_ROOT is invalid: ROS_ROOT [/opt/ros/fuerte] must end is directory named 'ros'", but this is the directory, i dont know why its telling me this.
One last thing, the tutorial tells me to execute this file: setup.sh, that contains this text: " #!/bin/sh source /opt/ros/fuerte/setup.bash export ROS_ROOT=/opt/ros/fuerte export PATH=$ROS_ROOT/bin:$PATH export PYTHONPATH=$ROS_ROOT/core/roslib/src:$PYTHONPATH export ROS_PACKAGE_PATH=~/ros_workspace:/opt/ros/fuerte/stacks:$ROS_PACKAGE_PATH export ROS_WORKSPACE=~/ros_workspace"
But i'm not sure this is the version for the fuerte version of Ros, because i just copied the electric version and changed a little bit so it would work on ros, maybe that's why im having those problems.
Thanks everyone.. :)
