The currently maintained and developed version of KnowRob is based on the 'catkin' buildsystem that has been the main ROS buildsystem since the Groovy distribution. This version is recommended for ROS Hydro and newer.
We have prepared different .rosinstall setup files that you can add to your ROS workspace as described here.
rosdep update cd ~/catkin_ws/src wstool merge https://raw.github.com/knowrob/knowrob/master/rosinstall/knowrob-base.rosinstall wstool update rosdep install --ignore-src --from-paths . cd ~/catkin_ws catkin_make
You are now done with the KnowRob installation. Make sure to set up your workspace after the installation and have a look at the Getting started guide for some hints how to proceed.
