Mesh Filtering process died on launching.

[shubhamwagh]

Hi,

On launching mesh_filtering launch file : roslaunch noether_examples mesh_filtering_demo.launch

It says the process has died! May I know what is going wrong?

started roslaunch server http://localhost:33195/

Can you run the command below from the workspace and report the output?

ldd devel/lib/noether/mesh_filter_server | grep vtk

@jrgnicho here is the output for the given command:

I haven't been able to reproduce your error I'd suggest a couple of things

• Run ldd and see if it's linked multiple versions of pcl

ldd devel/lib/noether/mesh_filter_server | grep pcl

If only one version shows, most like pcl 1.9.1, then that means it's only linked one version of the pcl library which is a good sign

At this point I would build the noether_filtering package in "Release with debug info" or in "debug" and then attach a gdb process to the mesh_filter_server node in the noether/launch/mesh_filter_server.launch to see where it fails.

which looks fine to me.

[jrgnicho]

Yes, it looks ok. I would run gdb as described in my earlier comment

[Beshario]

running cat /home/qbot/.ros/log/800b43bc-f759-11ea-8898-049226d2aab3/mesh_filter_server-3.log

can shed some light on what is happening.

[shubhamwagh]

Hi @jrgnicho I rebuilt it with RELWITHDEBINFO, I still get the same error. Kindly find the attached gdb debugger output.

Also @Beshario, I tried doing that earlier, but for some reason, it says the file is not present. So for the above output, I tried the following command line:

[jrgnicho]

@shubhamwagh could you run a backtrace when the node crashes. You should be able to do that with the bt command

[Levi-Armstrong]

@shubhamwagh Were you able to resolve the issue?

[shubhamwagh]

Sorry, I am no more using this library. Last time, I remember I couldn't resolve the problem. Instead created my own custom toolpath generation software from point clouds to meet our use case. Thanks for the help anyways.

[Levi-Armstrong]

Is your point cloud method for generating tool paths open sourced?

[shubhamwagh]

@Levi-Armstrong, apologies for late reply. It is not open sourced as it is part of company project and in development stage.
