Dear ROS users,

i tried to implement a C++ plugin (lets call it rqt_myplugin) following the tutorial rqt/Tutorials/Writing a C++ Plugin and the rqt_plugin ImageView. I am quite sure, that namespaces and classes are well defined in all necessary files. The problem is, that when i am trying to execute my plugin by running

rosrun rqt_myplugin rqt_myplugin

i get the message:

qt_gui_main() found no plugin matching "rqt_myplugin"

Rqt doesn't show the plugin neither.

Could you explain, how rqt is aware of my created plugin? I thought that it should be enough to source devel/setup.bash.

I am using ROS Hydro and Kubuntu 12.10 32Bit.

Did you add your plugin to your ROS path? I.e. what does `rospack find rqt_myplugin` return? Did you edit the plugin.xml file properly and doe the name match what your put in `rqt_myplugin`? Please provide us your current plugin.xml file.

Your plugin.xml seems ok. How is called your plug-in? (I mean the `.so` file)

@Thomas:

rospack find rqt_myplugin

delivers the path to my package folder in the catkin ws:

/home/ [...] /catkin_ws/src/rqt_myplugin

This is my plugin.xml:

<library path="lib/librqt_myplugin">
<class name="rqt_myplugin/CalibrationView" type="rqt_myplugin::CalibrationView" base_class_type="rqt_gui_cpp::Plugin">
<description>
An example GUI plugin.
</description>
<qtgui>
<label>My Plugin</label>
  <icon type="theme">system-help</icon>
  <statustip>Coming soon.</statustip>
</qtgui>
</class>
</library>

Please edit your question instead of replying to it. Especially in your case your question just switched from no answer to at least one answer which will reduce its visibility.
