Hope this finds you well.

We are following this “Connection to NVIDIA Jetson hardware - MATLAB - MathWorks India” site and getting error while connecting to MATLAB interface with JETSON ORIN NANO as mentioned below:

Error in MATLAB :

Error in nvidiaio.internal.launchServer (line 19)

loc_updateServer(obj);

Error in nvidiaboard/connectToServer

Error in nvidiaboard/initiatePeripheralAccess

Error in nvidiaboard/checkAndGetHardwareConfig

Error in jetson

Error in JETSON :[Linking]/usr/bin/ld: handler.o:/home/barc/MATLAB/server/frameReader.h:174: multiple definition of gstDataStrct'; server.o:/home/barc/MATLAB/server/frameReader.h:174: first defined here /usr/bin/ld: v4l2_cam.o:/home/barc/MATLAB/server/availableWebcam.h:29: multiple definition of wc’; handler.o:/home/barc/MATLAB/server/availableWebcam.h:29: first defined here/usr/bin/ld: frameReader.o:/home/barc/MATLAB/server/frameReader.h:174: multiple definition of `gstDataStrct’; server.o:/home/barc/MATLAB/server/frameReader.h:174: first defined herecollect2: error: ld returned 1 exit statusmake: *** [Makefile:19: build] Error 1

Please guide us with these errors for our future use.

Since no response in both MATLAB and NVIDIA forum, i found below related to the error, for experts to go through,

https://in.mathworks.com/help/matlab/matlab_external/resolve-build-error-multiple-redefinition-linker-errors.html

Above link mentioned possibiity of multiple definition of symbol error, when same header file is used by different source, hence it is confirmed that the MATLAB server which is required to be installed in the JETSON ORIN NANO for remote programming using https://in.mathworks.com/help/coder/nvidia/ref/jetson.html is failing to build

, require changes in the source files, finally this correction must be done in the 2023b jetson hardware support package being used by MATLAB when establishing the connection , however for now i can do trial and error to change the symbol namespace as local..please suggest if anything to be tried further, we cn edit the source files in the MATLAB server on JETSON.
