Hi Maxim,

cgejsv and zgejsv are LAPACK functions, which should be included in your 
BLAS. Are you sure you have a good OpenBLAS build and it's on the path? 
Or are you trying to compile against Apple Accelerate as your 
BLAS/LAPACK implementation?

Looks like you're also missing a -liconv or similar to link GNU libiconv?

Compiling Octave on a Mac can be tricky. I think your best bet is to use 
a package manager definition for it instead of trying to build from 
source yourself, unless you have custom build requirements.

Are you a regular MacPorts user, or did you just install it to get the 
build environment for Octave?

If you're a MacPorts user, I'd contact their octave port maintainer and 
see if they can bump their port to 6.2.0 so you can just install that 
instead of having to build yourself. (It's currently on 6.1.0; I assume 
that's why you're doing your own build here.)

If you're just using MacPorts to build Octave and are in a hurry, 
consider switching to Homebrew: the Octave.app project has a Homebrew 
formula for Octave 6.2.0 that has been successful against recent macOS 
releases. [1] And the core Homebrew Octave formula [4] is on 6.2.0, if 
you don't mind some GUI hiccups.

Or just download the pre-built Octave.app. [2] There's a beta for 6.2.0 
out. [3] Octave.app is primarily used for its GUI, but you can run the 
command-line octave from it just fine, too.

Cheers,
Andrew
