2018-08-08 01:58:10 -0500	marked best answer	hector_quadrotor_demo process dies Hi, so I'll make this as specific as possible, beginning with how created my workspace in kinetic. I tried several methods, because i was asked to preferably use "catkin build" instead of catkin_make: i created a folder in ~/kinetic_ws: catkin init Catkin workspace `/home/carsten` is already initialized. No action taken. WARNING: Source space `/home/carsten/src` does not yet exist. wstool init Didn't work aswell, so I used catkin_make which resulted in `echo $ROS_PACKAGE_PATH /home/carsten/kinetic_ws/src:/opt/ros/kinetic/share` I then rm build devel -rf so that I could compile using the catkin build command. So now that i have my workspace "properly" set up, I downloaded the following (meta?)packages into my /src folder: git clone https://github.com/tu-darmstadt-ros-p... git clone https://github.com/tu-darmstadt-ros-p... I had to download several tools: sudo apt-get install ros-kinetic-hector-gazebo sudo apt-get install ros-kinetic-gazebo-plugins ros-kinetic-gazebo-ros-control sudo apt-get install ros-kinetic-hector-models I couldn't build the package, I googled and found a solution using rm -rf ~/.catkin_tools Afterwards, i was able to compile: catkin build hector_quadrotor ------------------------------------------------------------- Profile: default Extending: [env] /opt/ros/kinetic Workspace: /home/carsten/kinetic_ws ------------------------------------------------------------- Source Space: [exists] /home/carsten/kinetic_ws/src Log Space: [missing] /home/carsten/kinetic_ws/logs Build Space: [exists] /home/carsten/kinetic_ws/build Devel Space: [exists] /home/carsten/kinetic_ws/devel Install Space: [unused] /home/carsten/kinetic_ws/install DESTDIR: [unused] None ------------------------------------------------------------- Devel Space Layout: linked Install Space Layout: None ------------------------------------------------------------- Additional CMake Args: None Additional Make Args: None Additional catkin Make Args: None Internal Make Job Server: True Cache Job Environments: False ------------------------------------------------------------- Whitelisted Packages: None Blacklisted Packages: None ------------------------------------------------------------- Workspace configuration appears valid.
