Different behavior after update

[TamirEll]

Hi Mathieu,
I updated RTAB to the latest version(I wanted to change some variables per your recommendation).
Since the update, I am not seeing any reconstruction and two windows are missing the the display.
In addition, when starting the application, I can see this error message:

/opt/ros/melodic/lib/rtabmap_ros/rtabmap: symbol lookup error: /opt/ros/melodic/lib//librtabmap_sync.so: undefined symbol: _ZN7rtabmap7Rtabmap4initERKSt3mapINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES7_St4lessIS7_ESaISt4pairIKS7_S7_EEERSB_b

Am I missing a default value the should be changed in the launch file?
anything else perhaps?



Best regards,
Tamir.

It looks like rtabmap_Ros is loading the wrong rtabmap library version. Did you upgrade both rtabmap and rtabmap_ros? Also make sure you don't have any rtabmap built from source remaining.

You can try to track the wrong rtabmap with:

ldd /opt/ros/melodic/lib/rtabmap_ros/rtabmap | grep rtabmap

You are correct. I didn't update all packages.
thanks!
