librealsense-2.55.1

[Task-DP3]

Ubuntu:22.04
NVIDIA Jetson AGX Orin
When installing librealsense-2.55.1, the following issue occurred. How can it be resolved?

Hi @Task-DP3 Which method did you use to install the librealsense SDK on your Jetson AGX Orin, please?

If you followed a set of installation instructions, please provide a link to them if possible. Thanks!

Hi, I installed the librealsense SDK on my Jetson AGX Orin by building from the official GitHub source. There are also scripts for one-click compilation. Both methods can encounter the same version mismatch issues between the Python bindings and the system SDK.

Here are some references I followed:

CSDN tutorial: https://blog.csdn.net/gitblog_00035/article/details/151542922

This particular error that you experienced has not been previously reported.

Your best chance of success on your Jetson Orin AGX may be to use the libuvc backend source code installation method described at #13810 (comment)

The libuvc_installation.sh build script should install librealsense 2.56.5 and the 2.56.5 version of pyrealsense2 at the same time once you edit the build script to add these flags to line 46:

-DBUILD_WITH_CUDA=ON -DBUILD_PYTHON_BINDINGS=bool:true

---

If you need version 2.55.1 specifically then you could try the following procedure:

1. Remove lines 35-39 from the libuvc_installation.sh script so that it does not download 2.56.5.

2. Go to the 2.55.1 version at the link below and download and extract the Source code (zip) file in the Assets file list at the bottom of the page.

https://github.com/IntelRealSense/librealsense/releases/tag/v2.55.1

3. Open the extracted librealsense 2.55.1 source code folder and navigate to the 'root' folder, which is the one with the list of files and folders. Then place the edited libuvc_installation.sh build script in this folder and run the script.

And it still does not work if you input the command rm ~/.realsense-config.json to remove the file that contains RealSense configuration details?

If that does not make a difference then I would recommend a complete wipe of the Jetson and reinstalling everything including Ubuntu, and installing librealsense using the libuvc backend method described above.

Hi @Task-DP3 Do you require further assistance with this case, please? Thanks!
