Hi All,
When I use rosrun to run an executable, I got a segmentation fault. The error message is simply: "Segmentation fault"
I want to debug the core dump file, so I followed this tutorial: http://wiki.ros.org/roslaunch/Tutoria...
However, I cannot find the core dump file. I am using ROS Indigo with Ubuntu 14.04 and my $ROS_HOME is empty. Can you help to identify this?
The coredump may be created in ~/.ros, or it may be created in the directory where you run rosrun, or it may not be generated at all if your system is not configured to generate core dumps (as noted in the tutorial).
If you can reproduce your problem easily and are having trouble obtaining core dumps, you may want to try following the directions in the tutorial for running your node in valgrind or gdb.

Have you looked in the
.rosdirectory in your home folder?I looked at the .ros directory. It's not there. (There is a file called roscore-11311.pid. I believe it is not the core dump file. )
You are correct;
roscore-11311.pidis not the file you're looking for.
