Greetings, all! Been a looooong time — far too long — since I poked my head in
here. On balance, even considering the pandemic, life has been good.
It’s been about as long since I’ve done anything with a camera that’s not built
into a cellphone, but I’m hoping to have a chance to remedy that. In
preparation, I’m looking to build my workflow back up bit by bit.
Long version short, I’ve got an M1 MacBook Air, which reports:
$ dispcal 2>&1 | head
Calibrate a Display, Version 2.1.2
Author: Graeme W. Gill, licensed under the AGPL Version 3
Diagnostic: Too few arguments
usage: dispcal [options] outfile
-v [n] Verbose mode
-d n Choose the display from the following list (default 1)
** No displays found **
-dweb[:port] Display via a web server at port (default 8080)
-dcc[:n] Display via n'th ChromeCast (default 1, ? for list)
-d dummy Dummy (non-existant, invisible) display
Also:
$ dispcal -D9
get_a_display called with ix 0
Found 1 screens
CFDictionaryGetValue returned NULL
dispcal: Error - Unable to open the default display
I tried installing both jam and ftjam through MacPorts, but both refused to
install. I didn’t bang my head against those very hard. I do, though, have
plenty of other ports installed, and I don’t remember having trouble installing
a port in quite some time.
As always, I’m happy to be a guinea pig.
Thanks,
b&
