Octave.app 64-bit?

[Richard L. Hamilton]

This might explain what's happening:

sh-3.2$ file /Applications/MacPorts/Octave.app/Contents/MacOS/Octave
/Applications/MacPorts/Octave.app/Contents/MacOS/Octave: POSIX shell script text executable, ASCII text

What would usually be the application executable is a shell script wrapper; maybe that's preventing certain utilities from determining the bit-ness of the app, or from doing so correctly.


sh-3.2$ cat /Applications/MacPorts/Octave.app/Contents/MacOS/Octave
#!/bin/sh

/opt/local/bin/octave-5.1.0 --gui "$@"


Examining the executable called by the wrapper:

sh-3.2$ file /opt/local/bin/octave-5.1.0
/opt/local/bin/octave-5.1.0: Mach-O 64-bit executable x86_64


it's 64-bit (at least in the precompiled port for Mojave).  All the rest of the executables and dynamic libraries in the package appear to be 64-bit too.  I didn't look inside static libraries, but I don't imagine they'd be any different.
