2021-05-06 14:24:44 -0500 | marked best answer | Spinning multiple nodes across multiple threads I have an application which dynamically spins up multiple nodes and needs to spin them (as they have subscribers). Quick example, stolen from here: https://answers.ros.org/question/3583... This example works totally fine and allows the spin to happen in a separate thread (which is what I want because my nodes do other threaded things as well). The issue I get is when i add a second node and attempt to spin it, I get This results in an Exception being thrown in the second thread: I realize there are other methods of composing multiple nodes but as I said, the nodes I'm building do a lot of other things in threads and are spun up dynamically by another process. Is there some method I'm missing to tell edit: Quick addition. The nodes I'm building inherit from |

2014-01-28 17:29:39 -0500 | marked best answer | rosmsg show in C++ Hello, I'd like a way I can recursively iterate all topics/types in C++. Essentially a rosmsg show through all types, down to the basic types. I've seen it done in Python using the function get_topic_class() but I have thoroughly searched and been unable to find a way to do this in C++. Anyone have any ideas? I really don't want to have to hard code all of my message types (we have about thirty custom message types). Thanks! |
2014-01-28 17:28:19 -0500 | marked best answer | rqt cpp plugin won't load I've been attempting to create a cpp plugin for rqt and am having trouble. I managed to create a base plugin and in trying to get ros messages to the plugin, my callback never gets called. That being said, I decided to go back to the tutorial (tried to post a link to it but failed) and build the complete basic plugin from scratch and just add a subscriber. Upon doing that I cannot get rqt to load the plugin. It shows in the plugins list but is not clickable (suggests I need to build it). I copied the code verbatim from the tutorial (although not positive if the CMakeLists.txt I did is correct or not) and it builds a library file. I'd really like to make the sample tutorial work as I'm not certain how my other plugin is working but the sample isn't. Any ideas or suggestions would be appreciated. Update: So we found the issue, apparently the rqt_gui cpp architecture is not calling any kind of rosspin() so that's why the callback isn't happening. Does this mean any C++ based rqt plugin will have to handle and thread its own rosspin()? |
