unmet dependencies for ros-melodic-rtabmap on Ubuntu 18.04 #292

Open swiss-knight opened 5 years ago

I'm trying to follow this tutorial : http://wiki.ros.org/rtabmap_ros/Tutorials/Tango%20ROS%20Streamer with a Phab 2 Pro from Lenovo and a Ubuntu 18.04 64bit based laptop which hosts the ROS master. The Tango light of the App is still red.

I guessed that I was missing the "rtabmap_ros" package (i.e. ros-melodic-rtabmap).

So I tried to install it but it fails;

$ sudo apt-get install ros-melodic-rtabmap

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ros-melodic-rtabmap : Depends: libpcl-dev but it is not going to be installed
                       Depends: libvtk6-qt-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I already have libvtk7-dev. If I try to installed the dependencies from the dependencies from the dependencies from the (...), I end up on this:

I don't want to mess up with these libraries. Is there an easy way to fix that or the only way is to proceed with this removal?

Computer information; Ubuntu 18.04 4.15.0-45-generic x86_64 GNU/Linux /rosdistro: melodic /rosversion: 1.14.3

Phone: Android 6.0.1 (Lenovo Phab2 pro) with both rtabmap and Tango Ros Streamer apps installed from the playstore.

libpcl-dev depends on vtk6. Do you really need vtk7? If I were you, I would uninstall it and install vtk6 instead. Otherwise, the much longer way is to rebuild from source PCL so that the PCL links on vtk7 instead. If you do so, you would have to rebuild also from source rtabmap and rtabmap_ros.

Okay, thanks. It's working with VTK6 under the hood.
