Hi,

I had to postpone this project because of my exams. Now I am back to it.

I was getting this error when I ran rtabmap_ros on rpi 2 with ubuntu (rtabmap without ros is working fine on rpi)-

Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".
[tcsetpgrp failed in terminal_inferior: Inappropriate ioctl for device]
Cannot access memory at address 0x0

 
Then I tried fiddling with the CoreNode.cpp. But even when I comment all the contents of the main function in CoreNode.cpp and do "roslaunch rtabmap_ros rgbd_mapping.launch rviz:=false rtabmapviz:=false" , I get the same error as above.

I tried running other catkin packages, they are working properly.

Can you please suggest me what part of code runs before CoreNode.cpp, so that I can pinpoint the cause of this error? Or any other method to remove this error.

PS : I am not able to run valgrind because of the following error -

Roslaunch got a 'No such file or directory' error while attempting to run:

valgrind /home/kapil/catkin_ws/devel/lib/rtabmap_ros/rtabmap __name:=rtabmap __log:=/home/kapil/.ros/log/e6fc13b2-0dfd-11e5-ba54-28d24442d63d/rtabmap-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.
The traceback for the exception was written to the log file

Thanks,
