  • multiple definition of gstDataStrct;
  • multiple definition of wc;
  • collect2: error: ld returned 1 exit status

• Context: The issue arises when attempting to establish a connection between MATLAB and the Jetson Orin Nano, specifically while executing commands related to server launch and hardware configuration.

• Hardware and Software Specifications: The problem occurs with the Nvidia Jetson Orin Nano and MATLAB 2023b. Specific configurations or versions were not detailed in the discussion.

• Frequency: It appears that this issue is not isolated, as multiple users have reported similar errors.

• Impact on User Experience: The inability to connect MATLAB with the Jetson board significantly hampers users’ ability to utilize MATLAB for development and testing on the Nvidia platform, affecting productivity and project timelines.

Possible Causes

Several potential causes for this issue have been identified:

• Hardware Incompatibilities: There may be compatibility issues between MATLAB 2023b and the Jetson Orin Nano, particularly if specific drivers or libraries are required.

• Software Bugs or Conflicts: The errors suggest possible bugs within either MATLAB or the libraries being used for interfacing with the Jetson hardware.

• Configuration Errors: Incorrect setup or configuration in MATLAB or on the Jetson board could lead to these connection issues.

• Driver Issues: Outdated or improperly installed drivers related to the Jetson board could cause failures in establishing a connection.

• Environmental Factors: Factors such as power supply fluctuations or temperature variations could potentially affect hardware performance and connectivity.

• User Errors: Misconfigurations by users, such as incorrect paths or settings in MATLAB, might lead to these errors.

Troubleshooting Steps, Solutions & Fixes

To resolve the connectivity issue between MATLAB and the Jetson Orin Nano, follow these comprehensive troubleshooting steps:

1. Verify Software Compatibility:

   • Ensure that you are using a compatible version of MATLAB with the Nvidia Jetson Orin Nano. Check MathWorks documentation for any specific requirements.

2. Update Drivers and Libraries:

   • Ensure all relevant drivers for the Jetson Orin Nano are up-to-date. Use the following command to check for updates:

     sudo apt update && sudo apt upgrade
     

3. Check Configuration Settings:

   • Review your MATLAB configuration settings for any incorrect paths or parameters. Ensure that your environment variables are set correctly, especially those related to CUDA and other Nvidia libraries.

4. Isolate the Issue:

   • Test connectivity with a simplified setup. For example, try running a basic example script that connects to the Jetson board without additional complexity.
   • Use different USB ports or cables if applicable to rule out hardware issues.

5. Review Error Logs:

   • Examine detailed error logs in MATLAB for additional context on what might be causing the failure. This can help pinpoint whether it’s a library conflict or a code issue.

6. Rebuild Affected Files:

   • If you encounter "multiple definition" errors, consider cleaning and rebuilding your project files in MATLAB. Use:

     make clean
     make
     

7. Consult Documentation:

   • Refer to official MathWorks documentation regarding connecting to Nvidia hardware for any additional steps or configuration guidelines.

8. Community Support:

   • If problems persist, consider reaching out on forums or community boards dedicated to Matlab and Nvidia development for further assistance.

9. Best Practices for Future Use:

   • Regularly update both your software (MATLAB) and hardware (Jetson) environments.
   • Maintain backups of working configurations to simplify recovery from future issues.

Unresolved aspects of this issue may include specific details about library versions that could be causing conflicts, which would require further investigation from both MathWorks and Nvidia support teams. If multiple users have successfully resolved their issues through updating drivers or configurations, these steps should be highlighted as recommended approaches for others facing similar problems.
