Make yellow error

I think @jyijyi was on the right track when they suggested you clear OCTAVE_ROOT.

OCTAVE_ROOT is an environment variable. You can unset an environment variable on the command line for a single command like this:

unset OCTAVE_ROOT

But, if this is being set by leaf, the variable will probably come back into existence when you change directory or exit and restart the leaf shell. There are ways to use leaf's env command to control those. See leaf help env for more information on that.

However, if you want to use Octave, you’ll need to install the Octave apps. Unsetting OCTAVE_ROOT or setting OCTAVE=0 will cause your build to exclude the Octave apps from your built image.

For mangOH Yellow, the instructions to get setup for development are on the mangOH project Wiki on GitHub: https://github.com/mangOH/mangOH/wiki/Building-the-Legato-"system"-(apps)-for-mangOH-Yellow

Thanks a lot for your answers
