Roslaunch got a 'No such file or directory' error while attempting to run: xterm -e gdb --args
Hi, guys! I want to debug in ROS Roslaunch. I add
launch-prefix="xterm -e gdb --args"
accoring to this page. When I add this debug line, there is the error Roslaunch got a 'No such file or directory' error while attempting to run:
xterm -e gdb --args /home/catkinws/devel/lib/ratslamros/ratslamlv /home/catkinws/devel/share/ratslamros/config/configstlucia.txt imagetransport:=compressed _name:=RatSLAMShow _log:=/home/.ros/log/858d4730-029a-11e6-af5e-c83a35db09fb/*-1.log Please make sure that all the executables in this command exist and have executable permission. This is often caused by a bad launch-prefix.
Also, I check the log, and I find the same hint.I found someone solve this.But not mine. I use ROS groovy and Ubuntu 12.04LTS. Thanks.

Do you have xterm and gdb installed? Can you run both manually?

Many thanks! I have tested gdb and works well manually in other program. In this program, Roslaunch is used to import some configure files.
