terminate called after throwing an instance of 'rv::XmlError'
what(): Error while parsing in line 1

This usually happens when the XML configuration file is malformed. Ensure that the xml files are well formed.

Try a validation tool, like https://www.xmlvalidation.com/, to validate the xml.

If the error is still thrown, even with a valid xml file, let me know and I will try to figure out what's the reason.

@jbehley I checked the XML file without a problem
I execute./visualizer directly in the bin directory

[jbehley]

Hmmm, it's hard to guess what might be the problem.

Either you try to directly call the visualizer with the path to the configuration file, i.e.,

./visualizer /path/to/config/default.xml

if this does not help, could you start the visualizer with gdb and report the backtrace, i.e.,

1. gdb ./visualizer
   This opens the debugger, then
2. (gdb) run
   To start the program, then
3. (gdb) bt
   To get the backtrace, which gives us an indication where the problem originated.

It seems that there is some problem with parsing the ../config/default.xml. But I unfortunately have no clue where the problem lies.

@jbehley According to what you say, I can use it already.
Can this map be saved to PCD or ply file?

[jbehley]

This is currently not supported.

How did you solve the problem with the xml? Did you start the visualizer explicitly with the path to the configuration xml?

[hunkyu]

yes ! I use directly ./visualizer /path/to/config/default.xml

Is there any way I can export 3D map model?

[jbehley]

As mentioned earlier.

We do not support exporting of the map.
