Error in installing KnowRob (ros-hydro-knowrob)

edit

Got it. Thank you.

I am getting this error now, after $ rosdep install knowrob ERROR: Rosdep cannot find all required resources to answer your query Missing resource knowrob ROS path [0]=/opt/ros/hydro/share/ros ROS path [1]=/opt/ros/hydro/share ROS path [2]=/opt/ros/hydro/stacks Plus, I re-installed Ubuntu 12.04 today. Gazebo is giving error as well. In mudworld, all links are not visible.

Then your system is not set up correctly, most probably your rosbuild/catkin setup is wrong. Please try if "roscd knowrob" works, otherwise check your setup here http://wiki.ros.org/catkin/Tutorials/using_rosbuild_with_catkin

Maybe I am doing something foolish. Please help me out. 1.I made a ROS space: http://wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironmenthttp://docs.ros.org/independent/api/rosinstall/html/rosws_ros_tutorial.html#rosws-ros-tutorial 2.rosws merge https://raw.github.com/knowrob/knowrob/master/rosinstall/knowrob-base.rosinstall rosws update rosdep install knowrob rosmake knowrob

There are two kinds of buildsystems, rosbuild and catkin. KnowRob still uses the older rosbuild, while the default in hydro is catkin. You can set up both systems to work together,you need to create a catkin WS first and then refer to it from rosbuild (Section 3.3 in the link I've posted).

Okay, Did what you said. Now keys are unresolved. : ratneshmadaan@ratneshmadaan-Inspiron-N5010:~/rosbuild_ws$ rosdep install knowrob ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: mod_srdl: Missing resource cmake_modules ROS path [0]=/opt/ros/hydro/share/ros ROS path [1]=/home/ratneshmadaan/rosbuild_ws/rosjava_jni ROS path [2]=/home/ratneshmadaan/rosbuild_ws/stacks/knowrob ROS path [3]=/home/ratneshmadaan/catkin_ws/devel/rosjava_jni ROS path [4]=/home/ratneshmadaan/catkin_ws/devel/stacks/knowrob ROS path [5]=/home/ratneshmadaan/catkin_ws/src ROS path [6]=/opt/ros/hydro/share ROS path [7]=/opt/ros/hydro/stacks

This is in fact a ROS dependency that you can install with apt-get install ros-hydro-cmake-modules

Got everything. Thanks a ton.
