Hello,

When trying to install RosAria in Kinetic Kame using

rosdep install rosaria

I got this error:

rosaria: No definition of [libaria] for OS version [xenial]

It seems, that RosAria team have not yet released the binaries for Ubuntu 16.04.

I tried instead to install from source, but, when I call catkin_make, I get the following message:

Ok,

So finally, it was a conflict in python packages, it seems that both em and empy builds a package with the same name. So I just solved it by replacing em by empy:

pip uninstall em

pip install empy

Then I installed RosAria using the standard steps in the official RosAria documentation

Great! If you have time can you report this bug to genmsg, em and empy? If not let me know and I'll look into it more and report it. May I edit the title of this post to be more specifically about this Python package problem (and also the libaria installation as well.)

Yes of course you can change the title. I reported the problem here, but I didn't dig deeper in genmsg code

Horse-man ( 2016-05-31 22:52:08 -0500 )edit

I guess I can't change the title. I was going to change it to something like "Problems building RosAria: errors with rosdep install libaria, and generating BumperState.msg code (em.Interpreter attribute not found in genmsg)". If you change it that might help others find the solution to this problem

You can just install ARIA from http://robots.mobilerobots.com/wiki/Aria. (The "Ubuntu 12 or Later" package will work fine.) Then don't use rosdep install rosaria, just run catkin_make (or catkin_make --force-cmake if necessary).

(Someone used to repackage libaria for each version of Ubuntu but they are not working on RosAria any more. Anyone is welcome to volunteer... or we will just switch back to manually installing libaria before building RosAria.)

P2OS is working on Kinetic if you want a temporary solution

ok thanks @ReedHedges, your commit solved the first part (rosdep error), but still catkin_make --force-cmake still rise the error and don't create the executable of RosAria. I think the error now is about em package but this one is installed, and if I uninstall it, I get No module named em msg

This seems like a problem with Kinetic's genmsg or your installation. Seems to work fine for me, I've installed Kinetic from Ubuntu packages. Maybe make sure your ros-kinetic-genmsg package is up to date, or rebuild a new version from source if you're doing it that way?

regarding a similar problem: ROSARIA -- Impossible to Install

@ReedHedges updating genmsg and other packages didn't solve the problem, I even tried to reinstall ROS from source, and the problem with RosAria was the same @daniel_dsouza the problem looks similar, but even when I tried your steps, it was the same error when building catkin
