[Rock-dev] [Rock-users] Problems to get ROS-Rock working in all branches (Ubuntu 12.04)

[Essen von Mathias]

Hi Steffen,

In master, rock.ros goes now through autoproj, but  ROS doesn't get "identified" at runtime. E.g. TRANSPORT_ROS variable remains undefined when calling rock-display. 

In Orocos::ROS::available? 
         defined? TRANSPORT_ROS  # not defined when coming here (line 4 of tools/orocos.rb/lib/orocos/ros.rb)

Installing of ROS packages with aup works, but user needs to make the directory /rock/ros first. Otherwise you get :
"ros has no VCS, but is not checked out in /opt/rock/ros". Apparently I was mislead by the error message. I should've read it "directory missing". 

I was wondering if this was the problem in the first place? Perhaps I should've just created directory rock/ros prior to installation of rock.ros.

I also tried "aup ros", but rock-display still didn't show ROS's name service. 

BR,
Mathias

Hi Mathias,

This should be fixed now (do an autoproj update)

There is support for catkin packages to be build by autoproj, they all
got selected by the  -rock.ros line.

Recently autoproj seems to check if a repo that is "none" has some code
in the package folder (or at least a folder). But no ros folder existed
and autoproj raised the error.

I removed these packages from the default install now. Should fine now.

You can load/build ros packages defined in
autoproj/remotes/rock.ros/catkin.autobuild by aup and amake (i.e. aup
moveit/core) or autoproj in general.

All it does is downloading the source package and invoking catkin in the
main folder AUTOPROJ_CURRENT_ROOT/ros

BUT the dependencies for installing packages there are not properly set
there.


Best, Steffen
