Re: Octave on Mac and Java

[David]

Sorry Sebastian, didn’t realise you were suggesting one or the other approach, 
my mistake. 


I don’t have much command line experience with the Mac… although was a 
programmer in a previous life… I ran the command 

brew install homebrew/science/octave --with-java


... otherwise it was complaining about not finding octave



Full output is:

macTaff:local David$ brew install homebrew/science/octave --with-java

I only installed homebrew for the first time a few hours ago, so assuming no 
problems there.


Thanks for your assistance!
