opencv-4.2.0 source-based installation is not used to compile rtabmap_ros

edit

The cleanest way would be to remove opencv system binaries (sudo apt remove libopencv*). This will remove cv_bridge and all ros packages depending on it, so you would have to rebuild cv_bridge and all packages you need depending on it from source (clone them in your catkin workspace). Then make sure to rebuild/install rtabmap library so that it is linking on your opencv version

Hi Matheu,

Now, those warnings are not coming anymore after removing the cv_bridge and other packages having prebuilt opencv dependencies. However, when I launch rtabmap.launch file, the following errors show up.

In case important, Currently, I compiled rtabmap_ros-0.20.7-noetic (edited in the first post too). I am using ubuntu-20.04, gcc-10.3.0. System specs: CPU-i7-11375H. The above-mentioned error did not arise earlier for rtabmap-0.20.7-melodic version.

See step A from this issue to debug "process has died" errors, make sure to copy/paste here the full "backtrace" from gdb.

Following is the output when I launch only rtabmap node.

It is given in two separate comments.

Hi, I saw the post you had referred to. Then, I reinstalled g2o-20201223_git tag (g2o master branch throws an error as it does not contain a member variable VertexSBAPointXYZ), and gtsam-4.0.3 in debug mode. Then, I installed rtabmap-0.20.7-noetic. Subsequently, I tried to run rtabmap-console with gdb. The outcome is provided here. Following that, I also tried running it with Valgrind. The corresponding output is divided into two consecutive links. (link1, link2)

Please look into it.
