Hi Wilhelm,
thanks, your modification made all four buttons work !
This seems somewhat surprising to me at first glance, should the
backend not be strcmp'ed using "==0", providing
an own section for each backend :-) ? Anyway, it works, even if the
buttons are somewhat scrambled:
(Button press at scanner) -> (Action)
--------------------
Email -> PDF
PDF -> Email
Scan -> Copy
Copy -> Scan.
I also used string-triggers only. The buttons may have to be pressed for
a short period exceeding the polling interval.
Some minor possible pitfalls using the installations defaults of
scanbd-1.5.0 under Ubuntu 16.04:
- I removed the default package and configured the newer scanbd 1.5.0 as
described in the previous mail. I also used xinetd instead of the ubuntu
default
bsd-inetd for network scanner access although this should be of no
relevance.
- Wilhelms patch has to be applied to scanbuttond_wrapper.c (removed
assertion, return strings on any value of "button").
- In scanbd.conf: Group should be "saned". Make sure all paths refer to
/usr/local/etc/scanbd, scriptdir = /usr/local/etc/scanbd/scripts, ...
- The new path also enters into /lib/systemd/system/scanbd.service,
after changing that do "systemctl daemon-reload" and restart scanbd.
Now I am happy because of the four programmable buttons for my Odroid-U2
SoC which has no monitor attached to it :-)
Thanks again Wilhelm and Happy Easter !
