Re: Octave 4.2.1 gui won't launch on OS X El Capitan 10.11

[swope]

Thank for the tips, but I'm still having the same trouble. At this point
I'm going to give up on trying to use the Octave gui, and simply use the
--no-gui option.

My colleague with the same generation MacBook and El Capitan has the Octave
gui working with no problem, so I was hoping for similar luck.

While compiling from source, I saw:

`Warning: homebrew/science/octave: this formula has no --with-qt5 option so
it will be ignored!`
...
`Warning: homebrew/science/octave dependency gcc was built with a different
C++ standard library (libstdc++ from clang). This may cause problems at
runtime.`

Good to know. So for now I will use Octave in no-gui mode. Maybe I'll
re-visit in a few months' time.

Cheers.
