Help required for rtabmap installation on jetson nano

[Carlylepoc]

Hello @matlabbe I am having trouble while installing rtabmap on jetson nano, I don't know which installation process to follow as there are many methods out there. I have jetpack 4.6.1, intelrealsense sdk version 2.50, ros wrapper for intelrealsense verion 2.3.2, cmake version 3.10.2, kernel version , 4.9.253 tegra. Could you please help me out.
My end goal is creating 3d map of environment using intelrealsense camera d435. Also earlier I had tried some steps of installing rtabmap but i was geting error so I have formatted and want guidance from you.

Natively there are some issues because nvidia uses their own custom build instead of using original system dependencies. You may try building that docker image (combined with this one) but from nvidia L4T base image:

- FROM ubuntu:22.04
+ FROM nvcr.io/nvidia/l4t-base:r36.2.0

I know some people using latest Jetpack 6.1 on Orin running rtabmap_ros in container like this. They launch only the rtabmap node though without UI. However, following these instructions, you may be able to launch rtabmap standalone directly. BTW, maybe the already built arm64 images would "just" work on your jetson without rebuilding containers manually.
