Hi,

I'm trying to proifle my controllers written in the ros_control framework in Gazebo. To this end, I added the following argument in gazebo_ros/launch/empty_world.launch:

launch-prefix="valgrind --tool=callgrind --callgrind-out-file=/home/user/callgrind.out"

However, no output file is produced. Has anybody who tried profiling ROS controllers using the Valgrind/Callgrind toolchain a solution for this?

Thanks,

-Robert-

Hi Robert,

I ran the Turtlebot3 navigation with the same argument on move_base node in turtlebot3_navigation/launch/turtlebot3_navigation.launch, and the callgrind.out file was produced to the correct path.

Maybe you can use command sudo find / -name callgrind.out* to search the file.
