Segmentation error with urg node
I have been trying to connect a Hokuyo UST-10LX sensor that I`m pairing with a Kobuki using the ethernet port on my laptop in the following way -
sudo ifconfig enp0s25 192.168.0.20
roscore
And then using the following command to enable the ethernet tap
rosrun urg_node urg_node _ip_address:="192.168.0.10"
However, I keep getting segmentation fault(core dump) errors .I can ping the sensor successfully though.
The error is exactly as follows -
Segmentation fault(コアダンプ）
which basically just means segmentation fault(core dump). There`s nothing other than this to work with.
Can someone help me with this? I`m just starting out and seem to be stuck here.
Can you please update your question with a full copy and paste of the error?
I`ve updated it but sadly thats all that its showing.
Could you maybe get the backtrace from gdb then?
I gave up and installed a fresh copy of Ubuntu with ROS from scratch. The urg_node command was not working even without specifying any parameters.It kept giving segmentation fault error every time.Given that it was 2 year old install that my senior gave me, I guess it was better to resintall everything to start with. Everything is working well now.
