2017-01-19 14:02:32 -0500 | commented question | Is catkin tools compatible with pluginlib? I will close this question and try catkin_tools in a clean environment. If I still have trouble, I will create a new question. |
2017-01-19 13:59:27 -0500 | commented question | Is catkin tools compatible with pluginlib? Thank you for the suggestions. Using my release profile didn't work at all. I now I believe that the only reason the debug profile works for nodes is that it is searching the catkin_make devel directory. The issue is therefore not with pluginlib, but with my catkin_tools profiles. |

2017-01-13 17:02:40 -0500 | asked a question | Is catkin tools compatible with pluginlib? Some time back, I made the switch from catkin_make to catkin_tools. For the most part, everything works fine. However, my custom plugins are no longer found. Let me emphasize that my plugins (custom displays for RVIZ) work perfectly when I compile with I created a debug profile using catkin tools with suffix 'debug'. The workspace extends However, if I try to load my plugin, only the library file created by catkin_make gets used. If I delete that file and then try to load my plugin in rviz, I can see my plugin in the list of available displays to add, but if I select it, I get this error: This happens even after I source the I can confirm that my plugin's library file exists in In order to debug this, I wrote my own test program that displays relevant information using
Having concluded that the problem was pluginlib not seeing my libraries, I looked at the source for pluginlib::ClassLoader to see what paths are searched for libraries. Catkin libraries appear to be found via the command

2016-07-28 10:32:16 -0500 | commented answer | Use ros-indigo-opencv3 alongside 2.4.8? However, I did encounter issues making my program into a nodelet: it compiled fine, but crashed at run time. Debugging revealed that it was trying to call the 2.4.8 library. Static compiling of 3.0 into my program didn't fix the problem. Lesson: run 2.4.8 and 3.0 code in separate processes. |
2016-07-28 10:27:15 -0500 | commented answer | Use ros-indigo-opencv3 alongside 2.4.8? I didn't use dpkg at all; I downloaded this package link text to my catkin workspace, applied the suggested changes to each affected CMakeLists, and compiled. |

2014-07-15 12:35:22 -0500 | answered a question | Where is ros-groovy in macports I think the real problem is that you can't 'sudo port ros-groovy' because there is no port with that exact name- you need to specify the full name, such as ros-groovy-core, etc. The order of the file URL and rsync is necessary as well, as noted by rleontie. |

2014-07-01 10:47:12 -0500 | commented answer | undefined reference to `urdf::Model::initFIle()' swig_kdl is the name of the library I am building, just put in the name of yours. MY_ADDED_LIBS should contain the libraries you use. Hope that helps. If not, you may want to create your own question so you can ask the community for help with your specific question. |

2014-07-01 08:55:23 -0500 | answered a question | undefined reference to `urdf::Model::initFIle()' Updated Answer Though my original solution was accurate, my explanation that the problem was Swig-related was incorrect: all things Swig are handled elsewhere. The problem was that I did not include 'urdf' in the variable MY_ADDED_LIBS, which is used by target_link_libraries. Adding it resolved the linking issue and I can load joint limits from the urdf just fine. My corrected CMakeLists.txt is below: |
2014-06-30 22:06:10 -0500 | asked a question | undefined reference to `urdf::Model::initFIle()' I am attempting to compile a cpp file that will read joint limits from a urdf. The lines of code at issue are: urdf::Model robotModel; robotModel.initFile("path/to/file"); I get the following error: undefined reference to `urdf::Model::initFile(std::basic_string<char, std::char_traits<char="">, std::allocator<char> > const&)' Commenting out 'robotModel.initFile(...)' eliminates the error, but defeats the purpose of the program. The error appears while linking. It appears that I am passing in the proper argument- it seems to match the documentation. In my CMakeLists, I have 'link_directories(/opt/ros/hydro/lib/)', which I have confirmed contains libkdl_parser.so and liburdfdom_model.so. The same type of error occurs if I use .initString(). What am I missing? |

2014-04-20 06:56:22 -0500 | marked best answer | Openni_launch does not recognize ''device_id" argument for PrimeSense I have a kinect and a PrimeSense v2 device. If I only plug in the kinect and set the device_id argument to "#1" for first device, it runs the kinect and displays the device_id. I can then use the 'device_id' argument to make sure that kinect is always referred to by a particular camera name. So far so good. If I plug in only the PrimeSense and select first device, it will find it, display the device_id, and run properly. However, when I enter in that device_id as an argument, I get this warning at run time: "~device_id is not set! Using first device". The only difference I can see is that the kinect id is 16 digits hexadecimal, while the PrimeSense is 10 digits decimal. I tried padding the PrimeSense id with spaces or 0's in front, but it still tells me the device_id is not set. I also a variety of other, made up id's. As far as I can see, the id must include a letter for it to be recognized. If I add characters in front of the actual id, it recognizes the string as a device_id but doesn't recognize it as matching the real device. Some goes for placing' on either side of the number- it is comparing '(number)' to ''(number)''- or converting the id to hexadecimal. What is the proper way to specify this device? I am working in a multi-device environment and need to assign the proper names to the proper devices. I know that there is an option to specify usb hubs or something, but I would rather not rely on port id's. Thank you for your help in advance. |
