[Jprogramming] J903-beta-v

[Ian Clark]

@ Bill

I'm running an Apple M1 Mini.
Following Eric's instructions, I've just upgraded to j903-beta-v.
It's using Rosetta to run x86_64 even though there's meant to be an arm64
binary in the app package

JVERSION

Engine: j903/j64/darwin

Beta-v: commercial/2021-11-16T21:51:35

Library: 9.03.06

Qt IDE: 1.9.4/5.15.2(5.15.2)

Platform: Darwin 64

Installer: J903 install

InstallPath: /applications/j903

Contact: www.jsoftware.com


Out-of-the-box, I get:

9!:56'cpu'

x86_64


i.e. NOT arm64


If I launch Terminal, I get:

ianclark at Ians-Mac-mini ~ % arch
arm64


Guessing from your instructions, the following command line ought to run
arm64 in j903, but I get errors…


ianclark at Ians-Mac-mini ~ % arch arm64 ./jconsole
arch: Can't find arm64 in PATH

ianclark at Ians-Mac-mini ~ % arch -arm64 ./jconsole
arch: ./jconsole isn't executable
ianclark at Ians-Mac-mini ~ % arch -arm64 jconsole
The operation couldn’t be completed. Unable to locate a Java Runtime.

…okay, maybe that's the wrong "jconsole"

and maybe I need the full path to the J executable


ianclark at Ians-Mac-mini ~ % arch -arm64 /Applications/j903/jcon903.app
arch: /Applications/j903/jcon903.app isn't executable
ianclark at Ians-Mac-mini ~ % arch -arm64 /Applications/j903/bin/jconsole
arch: posix_spawnp: /Applications/j903/bin/jconsole: Bad CPU type in
executable


Now I give up.

Anyway, why isn't macOS (Monterey, Version 12.0.1) finding the arm64 binary
by default?

Suggestions?
