2016-08-13 15:54:16 -0500 | commented question | Kinetic eclipse indexer problem I am having this exact problem. Only with certain, larger, projects though. Seems like it might be a size issue but the errors that eclipse reports during the indexing process, 'failed to parse file', are pretty useless. |

2016-01-13 13:32:13 -0500 | asked a question | How to have one catkin workspace rely on another Is there a generally accepted way to handle the case where I have some libraries that are generated in one catkin workspace and are used by a project in another catkin workspace? What I mean by handle is, how do I tell the project workspace where to find the libraries generated by the library workspace? I can imagine lots of ways to do this using symbolic links and/or environment variables but they all seem somewhat fragile or messy. I'm wondering if anyone has a way of doing this that they like. |

2015-05-12 15:38:10 -0500 | asked a question | Calling SWIG to create C++ python bindings from a catkin package I have some C++ code for which I would like to create python bindings using SWIG. I can do this using plain old CMake but keep running into problems when using catkin. Has anyone ever tried to do this? I have searched around quite a bit but have not been able to find anything on this subject. |

2015-04-17 11:23:53 -0500 | commented question | timestamps for ros topics not updating smoothly Thanks for the response. I updated my post to address your questions. |
2015-04-16 19:17:23 -0500 | commented question | timestamps for ros topics not updating smoothly No, nothing like that. Just publishing a bunch of sensor and state data. |
2015-04-15 18:57:28 -0500 | asked a question | timestamps for ros topics not updating smoothly I noticed that the timestamps associated with my topics is not updating smoothly. It will go for several messages without changing (or changing by some very small amount), then change a lot all of a sudden. This is very obvious when looking at rqt_plot because you end up getting a bunch of points right on top of one another, then a large jump along the x axis, then a bunch more points on top of each other. The problem is also present in bag files. I did notice that I can cut down on the number of messages I am publishing and at some point the problem goes away. Really not sure what is going on here. Any help is appreciated. Update To clarify, the timestamps I'm referring to are not timestamps within my ros topics, they are the timestamps automatically generated by ros for all topics that are published. Here is an example of what I am talking about with rqt_plot I'm publishing the following topics at 1000Hz (although I see the problem even if I publish them as slow as 50Hz). The topics I'm publishing have the following structure: /pose I'm publishing about 5 topics of this general size and structure. Is this just too much data for the ros messaging infrastructure to keep up with? It certainly doesn't seem like it should be. |
