I have just started with ROS and I am following one of my first beginner tutorial "Writing a Simple Publisher and Subscriber (C++)".

I am receiving an error when I run catkin_make or catkin_make install

This is my terminal:

lucadg@luca-Inspiron-3543:~/catkin_ws$ catkin_make install
Base path: /home/lucadg/catkin_ws
Source space: /home/lucadg/catkin_ws/src
Build space: /home/lucadg/catkin_ws/build
Devel space: /home/lucadg/catkin_ws/devel
Install space: /home/lucadg/catkin_ws/install
**Invalid package manifest "/home/lucadg/catkin_ws/src/beginner_tutorials/package.xml": The manifest contains invalid XML:
mismatched tag: line 60, column 2**

Below a copy of my package.xml file which I checked and everything seems to be ok, line 60 is the last word, the closing tag of package.

This is my package.xml

<?xml version="3.0"?>


  <description>The beginner_tutorials package</description>

  <!-- One maintainer tag required, multiple allowed, one person per tag -->
  <!-- Example:  -->
  <!-- <maintainer email="">Jane Doe</maintainer> -->
  <maintainer email="">Luca Di Giammarino</maintainer>

  <!-- One license tag required, multiple allowed, one license per tag -->
  <!-- Commonly used license strings: -->
  <!--   BSD, MIT, Boost Software License, GPLv2, GPLv3, LGPLv2.1, LGPLv3 -->

  <!-- Url tags are optional, but mutiple are allowed, one per tag -->
  <!-- Optional attribute type can be: website, bugtracker, or repository -->
  <!-- Example: -->
  <!-- <url type="website"></url> -->

  <!-- Author tags are optional, mutiple are allowed, one per tag -->
  <!-- Authors do not have to be maintianers, but could be -->
  <!-- Example: -->
  <!-- <author email="">Jane Doe</author> -->

  <!-- The *_depend tags are used to specify dependencies -->
  <!-- Dependencies can be catkin packages or system dependencies -->
  <!-- Examples: -->
  <!-- Use build_depend for packages you need at compile time: -->
  <!--   <build_depend>message_generation</build_depend> -->
  <!-- Use buildtool_depend for build tool packages: -->
  <!--   <buildtool_depend>catkin</buildtool_depend> -->
  <!-- Use run_depend for packages you need at runtime: -->
  <!--   <run_depend>message_runtime</run_depend> -->
  <!-- Use test_depend for packages you need only for testing: -->
  <!--   <test_depend>gtest</test_depend> -->

  <!-- The export tag contains other, unspecified, tags -->
    <!-- Other tools can request additional information be placed here -->
                                                                                                                           60,1          Bot

It looks like a couple of your dependencies don't have good close tags:


Sometimes the XML parser doesn't realize there's an error until it gets to a close tag, so you have to look at the error message too, not just the line number.

<?xml version="3.0"?>

Was that auto-generated @lucadg? Afaik, there are only two valid values for version: 1.0 and 1.1 (see wikipedia/XML - Versions fi).

Thank you @ahendrix, I thought that was the right line number. Also I've changed the xml version by mistake, it should be 1.0

Yes, the error was that some of the closing tags were incorrect. Read your XML carefully and make sure that there's a close tag for every open tag.
