[sane-devel] Agfa Snapscan 1212U, with SANE, on El Capitan

Mon Sep 27 05:08:41 BST 2021

Hi Ralph,

I'm guessing your recent circular refers to sane-backends (of which I
have version 1.0.25).
Thanks for that, though I'm still stuck on front ends.

I recently tried to install xsane (partly prompted by its entry on
Apple's App Store). It required Homebrew; I think many of their files
duplicate ones already installed by Sane. It took a long time to weed
out duplicates & symlink the files, not to mention about 1 GB of
downloads.
Anyhow, I followed the App Store's advice:

"Run brew install xsane. Done! You can now use xsane."
Rubbish! This is what resulted -

miMac:~ Niels$ brew list xsane
Error: No available formula or cask with the name "xsane".
&
miMac:~ Niels$ brew info xsane
xsane: stable 0.999

build-error: 0 (30 days)

The Ubuntu page gave the following commands, to install files for
xsane and text recognition:

sudo apt-get install xsane
&
sudo apt-get install gocr cuneiform tesseract-ocr

I'm not sure these are suitable for Mac's Terminal (& I've been warned
about this "sudo" stuff). Any advice?

The GitHub site yielded a file, xsane-0.999.tar.gz, along with what
looks like a Linux compilation page (?). It mentioned 'bottles' of
xsane for macOS 10.15 (Catalina) down to 10.12 {Sierra); the next step
was "x86_64_linux", possibly instead of macOS 10.11 (El Capitan).

So woe is me, or so it seems. Again.
Niels
