Hello,

I am doing my master thesis on implementation of object detection techniques on GPU. For that I need to implement a method called lark. I found that code as a package "larks" in "object_recognition_experimental" stack. But i didn't understand how to run that package. I tried through various steps but i couldn't. And while i am trying to install dependencies using "rosdep install larks" i am getting an error

Failed to find rosdep libsoci for package larks on OS:ubuntu version:10.10 
ERROR: ABORTING: Rosdeps [u'libsoci'] could not be resolved

Could you please help me.

Thanks & Regards,

It looks like the rosdep.yaml file for the object_recognition stack doesn't include a line for Ubuntu 10.10. A ticket should be filed against object_recognition https://code.ros.org/trac/wg-ros-pkg/query?component=object_recognition&status=assigned&status=new&status=reopened">here but until that gets fixed one workaround is to edit the rosdep.yaml file in the object_recognition stack root and duplicate the line which starts with 10.04, changing the 10.04 to 10.10.

When I did this and reran rosmake in the rein package I got an error about soci.h still not being found, but I fixed this by running make clean in the rein package folder and then rerunning rosmake. At that point I could successfully run rosmake larks.

Hi pbrook, Thanks for responding to my question. Now i can successfully run "rosmake larks". But no executables are generated (bin folder is empty). So how can i run larks package after building it. Could you please tell me?

Thanks&Regards Venu Gande

Sorry for the delay, I was caught up with some things in the lab. As far as I am aware larks generates a shared library which can be linked against for your own code or used in the context of the recognition infrastructure (rein). I'm not an expert with rein, so maybe somebody who is could chime in?

Hi peter, Thanks for your reply. So does it mean we cant run larks as we run turtlesim demo? And could you please look at my another post http://answers.ros.org/question/983/problem-in-launching-lark_traininglaunch-file .
