Error Loading Shared Libraries on Nvidia Jetson Orin Nano Dev Board

Issue Overview

Users are encountering an error message while attempting to load shared libraries on the Nvidia Jetson Orin Nano Dev board. The specific error reported is:

error while loading shared libraries: /usr/lib/aarch64-linux-gnu/tegra/libgstreamer-1.0.so.0: file too short

This issue arises when using JetPack version 5.1.2, particularly during the operation of a detection inference Docker container. Users have noted that the same setup works without issues on JetPack version 5.1.1 and that rolling back to version 5.0.2 resolved similar issues on other devices like the AGX Xavier.

The error seems to occur consistently when users attempt to create camera objects or run applications that depend on GStreamer, suggesting a compatibility problem with the library versions included in JetPack 5.1.2.

Possible Causes

Several potential causes for this issue have been identified:

• Library Incompatibility: The GStreamer version included in JetPack 5.1.2 may not be fully compatible with the applications being used, leading to the "file too short" error.

• Incomplete Installation: Missing libraries, such as libnvgstreamer, may not have been installed correctly during the flashing of JetPack, resulting in runtime errors.

• Flashing Errors: Issues during the flashing process could lead to incomplete or corrupted files, causing shared libraries to be unreadable.

• Docker Configuration: Running applications inside Docker containers may introduce additional complexities, such as linking issues with shared libraries.

• User Misconfiguration: Incorrect configuration settings or commands may lead to these errors, especially if users are unfamiliar with the environment.

Troubleshooting Steps, Solutions & Fixes

To address the issue, follow these comprehensive troubleshooting steps:

1. Verify Installed Libraries:

   • Check if the required GStreamer libraries are present and correctly linked:

     $ ll /usr/lib/aarch64-linux-gnu/libgstreamer-1.0.so*
     

2. Reinstall Missing Libraries:

   • If libnvgstreamer is missing, copy it from a working system or reinstall it:

     $ sudo cp /path/to/working/libnvgstreamer.so /usr/lib/aarch64-linux-gnu/
     

3. Reflash JetPack:

   • If issues persist, consider reflashing JetPack 5.1.2 using the SDK Manager:
     • Ensure your board is in recovery mode by connecting pins 9 and 10 while powering it on.
     • Use SDK Manager to flash the image:

       $ sudo ./sdkmanager
       

4. Test Outside of Docker:

   • Run your application outside of Docker to isolate whether the issue is related to Docker configuration.

5. Rollback to Previous Version:

   • If immediate resolution is needed and compatibility issues persist, consider rolling back to JetPack 5.1.1 or 5.0.2 where no issues were reported.

6. Update Environment Variables:

   • Ensure that your environment variables are set correctly for GStreamer:

     export LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu/tegra:$LD_LIBRARY_PATH
     

7. Check for Updates:

   • Regularly check for updates or patches from Nvidia that may resolve compatibility issues in future releases of JetPack.

8. Consult Documentation:

   • Refer to the Jetson Orin Nano Developer Kit User Guide for detailed setup instructions and troubleshooting tips.

9. Community Support:

   • Engage with community forums for additional insights or similar experiences from other users facing this issue.

By following these steps, users should be able to diagnose and resolve the shared library loading error effectively while utilizing their Nvidia Jetson Orin Nano Dev board in various applications.
