Download and install openslam_gmapping
Hi,
I am a beginner to ROS and I have successfully downloaded ROS Indigo. I am using Ubuntu as my OS. I would like to install the package openslam_gmapping on ROS from the source : https://github.com/ros-perception/ope... .
I have been following tutorials to familiarize myself with ROS, among them, I followed this post to attempt to download and install a package: http://answers.ros.org/answers/115386...
Installing hector_slam from the above post was successful and I even managed to run it. However, when I followed the steps of the same post to install and run openslam_gmapping, I was presented with a lot of errors, among them:
rachdar@ubuntu:~$ source /opt/ros/indigo/setup.bash
rachdar@ubuntu:~$ mkdir slam_gmapping
mkdir: cannot create directory ‘slam_gmapping’: File exists
rachdar@ubuntu:~$ mkdir slam_gmapping
rachdar@ubuntu:~$ cd slam_gmapping

rachdar@ubuntu:~/slam_gmapping$ wstool merge slam_gmapping_catkin.rosinstall

Add new elements:

Config changed, maybe you need run wstool update to update SCM entries.

I don't know what these errors mean. Can someone help please? Thanks a lot!
I am creating this .rosinstall file in gedit text editor:
- git:
uri: https://github.com/ros-perception/slam_gmapping.git
local-name: src/slam_gmapping
version: catkin
It looks like you have a bogus entry in your
.rosinstallfile of your workspace. Can you post it? How did you change your workspace to includeslam_gmapping? What commands did you run to get this error, e.g.wstool?Please edit your question to include longer content like this, comments are not suited for this purpose.
You should not be using
roswswith catkin, you should instead usewstool, see: http://wiki.ros.org/wstoolyes, you're right. Thanks I will try to use wstool and follow this procedure:
1) mkdir <folder> 2) cd <folder> 3) wstool init 4) wstool merge <the rosinstall="" file="" responsible="" for="" the="" source="" url=""> 5) wstool update
is this correct? I have added the full code in the question. Thanks a lot!
I tried working with wstool but I got the same error. I updated my question with the code I'm using and the .rosinstall file im creating in a text editor. I'd appreciate any help since I'm extremely new to this and I need ROS for my project! Thanks a lot!!
