MATLAB: MATLAB Coder: How to setup the environment variables on ARM targets to point to the ARM Compute Library

Question

I see a few deep learning networks supported for code generation using MATLAB Coder:

• Deep Learning Networks and Layers Supported for C++ Code Generation

And I've seen the question here about building the ARM Compute Library:

• MATLAB Coder: How do I build the ARM Compute Library for Deep Learning C++ code generation and deployment?

The next question I have is, how do I set the environment variables on ARM targets to point to the ARM Compute Library?

Answer 1

To avoid build failures on ARM hardware targets, such as the Raspberry Pi and Hikey960, you must set the necessary environment variables non-interactively.

For example, with the ComputeLibrary folder installed under ~, the user home directory, and the ARM Compute libraries stored at ~/ComputeLibrary/lib, you can add this code block to the file ~/.bashrc:

#Set below block, if you use your hardware non-interactively (through ssh from remote host or tty/new terminal onto local machine)
case $- in 
    *i*) ;; 
      *) 
      export ARM_COMPUTELIB=~/ComputeLibrary 
      export PATH=${PATH}:~/ComputeLibrary 
      export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:~/ComputeLibrary/lib
      return;;
