this question might be better suited for px4 forums, but no one replies there.

When I try to launch a particular node/module for ROS using a launch file on jetson TX2, it terminates and shows this error,

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_M_construct null not valid
[local_planner_node-2] process has died [pid 20132, exit code -6, cmd /home/user/catkin_ws/devel/lib/local_planner/local_planner_node __name:=local_planner_node __log:=/home/user/.ros/log/80e889fe-d9b5-11eb-8fd5-48b02d0f174f/local_planner_node-2.log].
log file: /home/user/.ros/log/80e889fe-d9b5-11eb-8fd5-48b02d0f174f/local_planner_node-2*.log

the same package with the same launch file works on my intel laptop, both have the same ros melodic installed, and both have ubuntu 18.04 installed. (laptop 18.04.5, Jetson 18.04.3).

I understand that this might be a setup/environment problem, but i am not able to determine the difference.

Log files, launch file, and terminal outputs can be seen here.

Any help is appreciated, thanks.

    The error is caused by passing `NULL` into `std::string`s constructor. Why this happened is unknown as we need to see a [mcve]. – Richard Critten Jul 02 '21 at 14:44
  • It was the wrong version of CMAKE, that caused errors in find .. code. that caused null to be passed to a string variable. – aamir Jul 02 '21 at 19:59
