MultiLibraryClassLoader Error
Hello everyone,
I'm writing a rviz panel.
When I change namespace (tiffer_panel -> Tiffer) in my code, and change the PLUGINLIB_EXPORT_CLASS.
#include <pluginlib/class_list_macros.h>
PLUGINLIB_EXPORT_CLASS(Tiffer::TifferPanel,rviz::Panel )
After Compiled, when I run rviz with this panel, got this
PluginlibFactory: The plugin for class 'Tiffer' failed to load. Error: MultiLibraryClassLoader: Could not create class of type tiffer_panel::TifferPanel
It seems not change. But when I change the namespace back (Tiffer -> tiffer_panel), it works well again...
Can someone tell me what's wrong with this?
Did you also update your
plugin.xml(or whatever you named that file)?I did not find this file,can you plz tell me where it is?
It doesn't have to have exactly that name. But there should be a file that registers your plugin with the ROS plugin system. It's typically called
plugin.xmland is referenced in your package'spackage.xml.Thanks, I'll try it later.
I had a similar error for a different problem, using the class_loader to make a MoveGroup capability. If anyone comes here searching: Make sure to modify not only the class files and the
xmlfile, but also theCMakeLists.txtto generate the executable for the class you are trying to load.
