First we ensure brew itself has the latest definitions:
<pre>brew update && brew upgrade octave</pre>
Then, we install Octave. To install only the command-line version use:
This would install octave with the default dependencies.
Note: QT may ask you to upgrade your OS (I was running 10.10 and had to upgrade to 10.14 to get it to work)
Note: The second command above also asked me to upgrade XCode to 10, which takes some time (>5GB file)
The default charting package in Octave is straight qt. However, on the Mac gnuplot often works better. To set up gnuplot, install (or reinstall) it with qt enabled:
Note: If brew complains about not having a formula for octave, the following command should fix it:
<pre>brew tap --repair</pre>
Note: If brew complains about unknown or ambiguous terminal type, and its possible you have installed gnuplot before, try running:
<pre>brew reinstall gnuplot --with-qt</pre>
The command below upgrades Octave and its dependencies to the latest Homebrew-supported versions:
<pre>brew update && brew upgradeoctave</pre>
Octave has many dependencies which will be downloaded and installed prior to Octave. The entire installation process can take a few hours, but precompiled binary packages called 'bottles' are available with default options for Octave and many of its dependencies.
