Dear members of the community,
I am experiencing a problem with the Matlab Coder. I am trying to implement the example "Deploy and Run Sobel Edge Detection with I/O on NVIDIA Jetson Nano". Actually, I am using an NVIDIA Jetson Xavier NX.
All the tests recommended at the beginning of the examples run without errors. However, when I run the codegen() command, I get the following error:
Error executing command "touch -c /pathToDir/sobel_edge_detection_deploy/codegen/exe/sobelEdgeDetection/*.*;make -f sobelEdgeDetection_rtw.mk -j4 all MATLAB_WORKSPACE="/home/nvidia/remoteBuildDir/MATLAB_ws/R2021b" -C /pathToDir/sobel_edge_detection_deploy/codegen/exe/sobelEdgeDetection". Details:
STDERR: In file included from /home/nvidia/remoteBuildDir/MATLAB_ws/R2021b/C/ProgramData/MATLAB/SupportPackages/R2021b/toolbox/realtime/targets/linux/src/MW_SDL_video_display.c:7:0:
/home/nvidia/remoteBuildDir/MATLAB_ws/R2021b/C/ProgramData/MATLAB/SupportPackages/R2021b/toolbox/realtime/targets/linux/include/MW_SDL_video_display.h:17:11: fatal error: SDL/SDL.h: No such file or directory
I am not able to figure out what the problem could be. The necessary Cuda libraries are installed on the host.
Thank you very much for your help.

Thanks for writing to us.
From the log I can say that it is the issue with the SDL libray installation on the target (on your NVIDIA hardware). SDL v1.2 must be installed on the target for the graphical visulaization operations. So, please take a look at the install and srtup instructions in the below page at "Software" section to install this library. This will resolve the above compilation failure.
