Using roslaunch with gdb gives error 'tcsetpgrp failed in terminal_inferior: Inappropriate ioctl for device'

edit

I'm not quite sure why you are getting the tcsetpgrp errors but maybe the terminal roslaunch provides does not support all features gdb wants.

I used this option: `launch-prefix="gdb --args" ` to launch gdb in my terminal however I got the same error: [tcsetpgrp failed in terminal_inferior: Inappropriate ioctl for device] each time I hit or continue from a break point.

Hello All,

I have the same problem... launch file is below (followed as above and changed the launch_prefix):

<launch>

<arg name="debug" default="false"/> <arg unless="$(arg debug)" name="launch_prefix" value=""/> <arg if="$(arg debug)" name="launch_prefix" value="xterm -e gdb --args"/>

<arg name="config" default="false"/> <arg unless="$(arg config)" name="command_args" value=""/> <arg if="$(arg config)" name="command_args" value="-d $(find inmoov6_moveit_config)/launch/moveit.rviz"/>

<node name="$(anon rviz)" launch-prefix="$(arg launch_prefix)" pkg="rviz" type="rviz" respawn="false" args="$(arg command_args)" output="screen"> <rosparam command="load" file="$(find inmoov6_moveit_config)/config/kinematics.yaml"/> </node>

</launch>

but I still get the same error message: tcsetpgrp failed in terminal_inferior: Inappropriate ioctl for device

Please advice on what I need to do specifically? to resolve it,
