2018-01-30 23:01:50 -0500 | marked best answer | OpenCV2 under Groovy not compiling Hi all, I am trying to fix a compiling problem for a week now, without success. :( Basically I am implementing this tutorial: http://wiki.ros.org/image_transport/T... However, when I compile, I get the following errors: In the CMakeLists.txt I have added the following according to the tutorial: In the package.xml I have added: On the website here ( http://wiki.ros.org/opencv2 ) I read OpenCV is deprecated under groovy and you need to install it as a third party library? However, why are there OpenCV packages installed under /opt/ros/groovy/include/opencv and /opt/ros/groovy/include/opencv2. Very confusing! :) Thanks, Ruud |

2017-08-10 17:02:15 -0500 | marked best answer | Compilation error whilst no coding errors Hi everyone, The strangest thing is happening; a weird compilation behaviour under Catkin Groovy, Ubuntu 12.04. Whilst running catkin_make, sometimes it will result in the following error although the code compiled just fine in a previous compilation. No code was altered in the meantime. Furthermore, the issue is temporarily 'solved' when I throw away the /build and /devel folders in my catkin workspace. Adding a CATKIN_IGNORE file in the presumed package of error does not help, as the error will then pop up for the next package. I wonder what causes the strange behaviour, it is quite inconvenient. |

2015-11-08 09:40:11 -0500 | commented answer | catkin_make failure due to Python Anaconda Awesome, that works! Good to know that CMake caches like that. |
2015-11-07 04:03:50 -0500 | commented answer | catkin_make failure due to Python Anaconda Hi William, Which build folder are you referring too, the Anaconda build folder? If I do so, wouldn't it imply that I cannot use the Anaconda when I switch back? I also need the Anaconda setup for another application, and recompiling and switching the whole time would not be optimal! Thanks! Ruu |
2015-11-06 09:57:31 -0500 | asked a question | catkin_make failure due to Python Anaconda Hi all, I have been cracking my head over this one. Recently I installed Anaconda Python for a different project. Today I tried installing ROS indigo on my 14.04 Ubuntu. When I do a catkin_make, it cannot find catkin_pkg: But it is installed under the python distribution that came with ubuntu: When I check which version of pyhon is being used I get: And when I turn off Anaconda python in the .bashrc I get: But running catkin_make in that case results in the same error above. Catkin keeps using: Please help! Ruud |

2015-07-07 08:32:58 -0500 | edited question | ImportError: No module named wx Hi all, When launching the node "joint_state_publisher" , I get the following error: I had a similar problem not long ago with a different module: see my question here I think it has something to do with my python installation, however I have no idea how to check if this is installed correctly.
