[Rock-dev] Rock-ROS communication

[Vicu-Mihalis Maer]

Hello,


I am trying to send some data between Rock and ROS. I am using ubuntu 18.04.

I have tried following the Rock/ROS bridge examples on the rock-robotics 
website but I ran into the issue described here: 
https://github.com/rock-ros/package_set/issues/1


However, reading through some e-mail threads in the rock-dev mailing 
list archive e.g.: 
https://www.mail-archive.com/rock-dev@dfki.de/msg01771.html

I have found that the package-set is not necessarily required. I have 
tried the method described in the e-mail thread above, but I have two 
problems. If I try installing the stable branch, I get an error from 
tools/roby and using the master branch, I get the following error:

ImportError: No module named genmsg
CMake Error at 
/opt/ros/melodic/share/catkin/cmake/safe_execute_process.cmake:11 (message):

The module does exist.


Is there any other way to establish communication between the two 
systems? I don't need to build ROS nodes within a rock workspace neither 
the other way around, just a message transport between ports and ROS topics.

Any help would be appreciated.


Best regards,

Vicu Maer
