RVIZ Fails to Load Plugins #924

Closed rhololkeolke closed 8 years ago

rhololkeolke commented 8 years ago

I have just gone through a source installation using homebrew on Max OS X 10.10.5. Everything builds properly, however, when I start RVIZ it fails to find any plugins. I get the following error messages when starting:

Looking at the log it appears as if pluginlib might be having trouble parsing the log file. Here is the relevant error I'm referring to:

[ERROR] [1443822410.598457000]: The XML document "/Users/rhol/ros_catkin_ws/install_isolated/share/rviz/plugin_description.xml" given to add must have either "library" or           "class_libraries" as the root tag

I've double checked and the path given in the log and it matches the path of the plugin_description.xml file. I've also double checked the XML and the root tag is indeed a library tag. I've run the plugin_description.xml file through an XML verifier to make sure the XML isn't malformed. The verifier finds nothing wrong with the XML.

I've also double checked the install_isolated/lib folder and libdefault_plugin.dylib is indeed there.

If you believe that this is an error with pluginlib let me know and I'll open an issue on that project.

wjwwood commented 8 years ago

Yeah, not sure about that. Can you post the plugin_description.xml from rviz and the rviz_plugin_tutorials packages?

Also try the obvious things, like delete the build, devel and install folders and build against from scratch, and in a clean terminal.

rhololkeolke commented 8 years ago

I've tried a clean build, but it still doens't work. I've attached the two plugin_description.xml files. I've checked the library paths and nothing seems out of the ordinary. The libs appear to be in the correct location.

Here is the rviz plugin_description.xml. I got this from the install_isolated/share/rviz folder.

I'm unable to reproduce this with my Mac book. There's nothing that would indicate to me what the issue might be. I'd suggest making sure you have the latest versions of the releases. Without being able to reproduce it or more information (I'm not sure what that information would be) then I probably cannot help further.

I changed the logging level to Debug and added some extra debug statements. It appears as if there is something wrong with my TinyXML version. I'm not entirely sure what could be causing the issue as I installed TinyXML with homebrew and it says that everything is the latest version. I've already tried uninstalling and reinstalling with homebrew and it doesn't seem to be working.

The error happens in the

template <class T> void ClassLoader<T>::processSingleXMLPluginFile(const std::string& xml_file, std::map<std::string, ClassDesc>& classes_available)

method inside the pluginlib/include/pluginlib/class_loader_imp.h file. I added some code to print the contents of the file specified in xml_file. It prints out the full XML file with no problems. So I know the correct paths are being provided and the file is readable as ASCII. However, I cannot get any valid data out of the TiXmlDocument class. I tried using the TiXmlPrinter class, but that gives a segfault. Printing things like the config->ValueStr() manually gives me gibberish.

Just to make sure that this was not an RVIZ specific problem I created a test package that just loads the same XML file and and attempts to parse and print the output with TinyXML. Same results. I double checked the paths being found by the CMake Module and everything looks correct. At this point I'm just assuming there is some weird bug with TinyXML for my particular system. I no longer think this is an RVIZ problem.

Thanks for the help.

@rhololkeolke Ok, well that is strange. Please post a comment here if you find the solution. Even though it is not an rviz issue, other rviz users might run into it.

bergercookie commented 4 years ago

FWIW, I stumbled upon the same issue.

I solved it by manually removing the $HOME/.rviz directory

@bergercookie How can be remove this error, I know you did remove ./rviz directory manually from $HOME

@kashifzr: you are missing a single plugin, while this issue is about missing all plugins. In your case, you probably simply missed installing the corresponding plugin package.

kashifzr commented 5 months ago

@rhaschke thanks for help. Sure i will try to resolve this by installing the corresponding plugin package
