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 : .

I have been following tutorials to familiarize myself with ROS, among them, I followed this post to attempt to download and install a package:

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

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:
    local-name: src/slam_gmapping
    version: catkin

It looks like you have a bogus entry in your .rosinstall file of your workspace. Can you post it? How did you change your workspace to include slam_gmapping? What commands did you run to get this error, e.g. wstool?

You should not be using rosws with catkin, you should instead use wstool , see:

yes, 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!!

The ROS package slam_gmappingdepends on another package openslam_gmapping. As of this writing, if you are on melodic distro, you need to install these packages from source since they are not released into melodic yet. For ROS packages installing from source implies cloning their repositories in the src directory of your workspace.

cd your_work_space/src
git clone
git clone

# [comment] navigate back to your_work_space directory
cd ..

Next, Install missing dependencies if any:

rosdep install --from-paths src --ignore-src

Next: Build your project

It worked!

Thank you very much for your answer
