2013-09-13 09:15:58 -0500	asked a question	Problem running PCL Tutorial? Hi all! I'm using Ubuntu 12.04 I was trying to follow the tutorial here wiki.ros.org/pcl/Tutorials. At step 4.1 I don't understand what TOP_DIR_YOUR_CATKIN_HOME is... Intuitively, I believed it was the directory ~/my_pcl_tutorial so I made a try. After doing that the command catkin_make reported error: The specified base path "/home/britsk/my_pcl_tutorial" contains a CMakeLists.txt but "catkin_make" must be invoked in the root of workspace. I copied the CMakeLists.txt and package.xml files to another place and ran the catkin_make command. It worked and then I restored the files. I'm not sure if this is necessary. Then I ran: rosrun my_pcl_tutorial example input:=/narrow_stereo_textured/points2. I received another error: rosrun my_pcl_tutorial example input:=/narrow_stereo_textured/points2 I looked around and found sth relating to rosws, so I tried rosws set ~/my_pcl_tutorial and got the error ERROR in config: Command requires a target workspace Please tell me how to make this tutorial work.
