MATLAB: I wants to generate cuda code using gpu coder for jetson xavier!

cudaGPU Codernvidia embedded

I tried to generate cuda code using gpu coder for jetson xavier.
but I met error when build code.
I referenced https://www.youtube.com/watch?v=0FPPBGAKw8k (mathworks tutorial)
Help!!!

  • Hi DaHoon,
    From the error log
    STDERR: /bin/sh: 1: nvcc: not found
    This seems to be an environment setup issue as the codegen is unable to find the nvcc compiler.
    Please follow the steps at the link here to setup the environment variables correctly to point to the cuda root directory:
    Please follow the example .bashrc file to ensure that codegen is able to remotely compile on the Jetson Xavier board.
